MATHESON, Circuit Judge.
After a sting operation involving two confidential informants and substantial audio and video surveillance, federal law enforcement officers caught Jesus Cabral-Ramirez ("Mr. Cabral") and Defendant-Appellant Maria Gutierrez de Lopez ("Ms. Gutierrez") attempting to transport an undocumented alien from El Paso, Texas to Denver, Colorado. A federal grand jury indicted Ms. Gutierrez on one count of conspiring to transport undocumented aliens, in violation of 8 U.S.C. § 1324(a)(1)(A)(v)(I).
At trial, the Government elicited testimony from Border Patrol Agent Brian Knoll about the immigration status of the individual Ms. Gutierrez allegedly conspired to smuggle. Agent Knoll also provided expert testimony that transporting undocumented aliens away from U.S./Mexico
The confidential government informants — who testified anonymously
The jury convicted Ms. Gutierrez as charged, and the district court sentenced her to three years of probation. She now appeals, arguing (1) Agent Knoll's testimony about the smuggled individual's immigration status introduced inadmissible testimonial hearsay in violation of the Federal Rules of Evidence and the Confrontation Clause; (2) Agent Knoll's expert testimony about the alien-smuggling trade was not helpful to the jury under Federal Rule of Evidence 702(a); and (3) the Government's use of anonymous testimony violated the Confrontation Clause of the Sixth Amendment.
Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.
In 2010, agents from the Federal Bureau of Investigation ("FBI") and United States Border Patrol ("Border Patrol") initiated "Operation Desert Tolls," a joint investigation into alien-smuggling organizations operating in New Mexico, western Texas, and Colorado. According to the Government, the operation received its "break" in June 2011 when agents apprehended "John Smith"
In November 2011, Mr. Smith received a call from Mr. Cabral, Ms. Gutierrez's co-defendant at trial. Mr. Cabral told Mr. Smith he would put him in touch with Ms. Gutierrez to "arrange for work" transporting undocumented aliens in exchange for payment. ROA, Vol. IV at 120. When Ms. Gutierrez called Mr. Smith, she informed him that she had found a person (later identified as Eneldo Valenzuela-Carrillo) seeking transport from El Paso, Texas to Denver, Colorado. The Government recorded various phone conversations between Ms. Gutierrez and Mr. Smith, as well as between Mr. Cabral and Mr. Smith, about the logistics for Mr. Valenzuela-Carrillo's paid transportation to Colorado.
On November 21, 2011, Mr. Smith picked up Mr. Valenzuela-Carrillo in El Paso and drove him to a motel in Las Cruces, New Mexico. The following day, another confidential informant, "James Jones,"
Meanwhile, Ms. Gutierrez picked up $1,500 (sent by Mr. Valenzuela-Carrillo's family) from a "MoneyCenter" at an Albuquerque Walmart.
Mr. Valenzuela-Carrillo then got into Mr. Cabral's pickup truck, and they drove to a private residence in the area. Once there, Mr. Cabral picked up some other individuals before heading north on Interstate 25. At the FBI's request, New Mexico state police stopped the vehicle south of Santa Fe. They took Mr. Valenzuela-Carrillo and another suspected alien into custody. The officers did not arrest Ms. Gutierrez on that date.
On May 8, 2012, a federal grand jury indicted Ms. Gutierrez on one count of conspiracy to transport an undocumented alien in violation of 8 U.S.C. § 1324(a)(1)(A)(v)(I).
Also at trial, the Government sought to prove that Ms. Gutierrez intended to "further" Mr. Valenzuela-Carrillo's illegal presence in the country by arranging transportation from El Paso, Texas, to Denver, Colorado. See 8 U.S.C. § 1324(a)(1)(A)(ii). Over defense counsel's objections, Agent Knoll provided expert testimony on the alien smuggling trade. He testified that the Government allocates substantially more resources to enforcing the nation's immigration laws near the southern border than in the interior of the country. Agent Knoll testified that in his experience, a smuggler would want to transport an undocumented alien away from a border town to avoid detection and decrease the chances of deportation. When asked whether, in his experience, moving away from the border would "further" an illegal alien's presence in the country, Agent Knoll responded, "Yes." ROA, Vol. IV at 359.
Finally, the Government offered testimony from the two confidential informants who had played a role in the sting operation. Because of a Mexican drug cartel's connection to the case, however, the Government asked the district court to allow them to testify anonymously to protect their personal safety. Over Ms. Gutierrez's Confrontation Clause objection, the district court agreed. The Government provided Ms. Gutierrez with background information on the confidential informants, including criminal history, compensation figures for cooperating with the FBI, and immigration status, but it refused to disclose their true identities. The two witnesses testified in open court under the aliases "John Smith" and "James Jones." They testified about their role in the transportation and their conversations with Ms. Gutierrez and Mr. Cabral, as well as Ms. Gutierrez's role in both obtaining the money and paying Mr. Smith for his efforts. On cross-examination, defense counsel elicited testimony on their criminal history, incentive to cooperate with the Government, and ties to Mexico.
The jury convicted Ms. Gutierrez as charged. The district court sentenced her to three years of probation, including eight months of required radio frequency("RF") monitoring. ROA, Vol. I at 113-14.
On appeal, Ms. Gutierrez argues the district court erred in allowing (A) Agent Knoll to testify about Mr. Valenzuela-Carrillo's
At trial, Agent Knoll testified as a fact witness about the processing of the undocumented aliens found in Mr. Cabral's car. According to Agent Knoll, he personally retrieved from the state highway patrol office the two individuals Mr. Cabral was smuggling and escorted them to Border Patrol for processing. Agent Knoll further testified that he "processed them as [he] normally would anybody encountered by the Border Patrol or another agency." ROA, Vol. IV at 331. When Agent Knoll was unable to identify the individuals by name, the prosecutor sought to refresh his recollection by briefly showing him their immigration files. Over the objections of Mr. Cabral's counsel, the district court agreed. See ROA, Vol. IV at 333-35.
Outside the presence of the jury, Ms. Gutierrez's counsel stated he did not "have a problem with the agent refreshing his recollection as to the names of these folks" but expressed his concern that Agent Knoll would introduce hearsay from these forms about the individuals' immigration status. Id. at 335. He also joined Mr. Cabral's Confrontation Clause objection. Defense counsel then asked whether Agent Knoll would "be allowed to testify that these two folks were undocumented aliens." Id. at 336. The district court responded that Agent Knoll had "conducted an investigation" and asked the prosecutor what he intended to ask Agent Knoll. Id. The prosecutor replied that he would inquire "what happened to these individuals at the end of the processing, what was the outcome of that ... process." Id. The district court then asked Agent Knoll "to [his] knowledge, what was the result of the investigation that was done regarding these two individuals you apprehended?" Id. at 350. Agent Knoll responded, "One went to Mexico, and the female stayed here anticipating that hearing in front of that judge." Id.
Ms. Gutierrez's counsel objected to "[a]nything that [Agent Knoll] is not personally aware of that represents a statement of one sort or another" — "everything that he didn't do personally that he read from a file or read off of a form that he wasn't involved in." Id. at 350-51. The district court overruled the objection and "allow[ed] [Agent Knoll] to testify" on the issue, concluding "the foundation has been laid for this witness who's got 28 years as a Border Patrol agent. He conducted an investigation." Id. at 352, 354.
After the jury returned to the courtroom, the prosecutor asked Agent Knoll what "was the outcome of your investigation?" Id. at 358. Agent Knoll testified that "I promised Edelmira [the other alien found in Mr. Cabral's car] for a — a hearing in front of an immigration judge sometime in the future, and she was released." Id. The prosecutor asked "what happened to Mr. Carrillo-Valenzuela [sic]?" Id. Agent Knoll recounted, "We called your office. Authorization for prosecution for illegal entry into the United States was authorized, and we prosecuted him for entering the country illegally." Id. The prosecutor followed up, inquiring "what happened to him after that?" Id. Agent Knoll responded, "Ultimately, he was removed to Mexico." Id.
"Although we review legal interpretations of the Federal Rules of Evidence de novo, we review a district court's evidentiary decisions for abuse of discretion." United States v. Griffin, 389 F.3d 1100, 1103 (10th Cir.2004). A district court does not abuse its discretion if its ruling "falls within the bounds of permissible choice in the circumstances and is not arbitrary, capricious or whimsical." United States v. Smith, 534 F.3d 1211, 1218 (10th Cir.2008) (quotations omitted). "[O]ur review of decisions to admit evidence over hearsay objections is especially deferential." United States v. Dazey, 403 F.3d 1147, 1166 (10th Cir.2005). We review a claim of error involving the Confrontation Clause de novo. See United States v. Kamahele, 748 F.3d 984, 997 & n. 4 (10th Cir.2014) (citing United States v. Townley, 472 F.3d 1267, 1271 (10th Cir. 2007)).
Ms. Gutierrez argues Agent Knoll's testimony about Mr. Valenzuela-Carrillo's immigration outcome introduced testimonial hearsay in violation of the (a) Federal Rules of Evidence and (b) the Confrontation Clause. We disagree.
Under the Federal Rules of Evidence, "[a] witness may testify to a matter only if evidence is introduced sufficient to support a finding that the witness has personal knowledge of the matter." Fed.R.Evid. 602. Although the proponent bears the burden of establishing personal knowledge under Rule 602, "[e]vidence to prove personal knowledge may consist of the witness's own testimony." Id.; see also 27 Charles Alan Wright & Victor James Gold, Federal Practice and Procedure: Evidence § 6028 (2d ed.2007) ("[P]ersonal knowledge may be established by the testimony of an in court witness without any elaborate foundation separate from the witness' description of the events in question.").
This standard is not difficult to meet. A court should exclude testimony for lack of personal knowledge "only if in the proper exercise of the trial court's discretion it finds that the witness could not have actually perceived or observed that which he testifies to." United States v. Sinclair, 109 F.3d 1527, 1536 (10th Cir. 1997) (quotations omitted); see also 1 Kenneth S. Broun, McCormick on Evidence § 10 n. 6 (7th ed.2013) ("[T]he foundational fact of personal knowledge under Rule 602 falls under Rule 104(b); and the trial judge plays only a limited, screening role, merely deciding whether the foundational testimony would permit a rational juror to find that the witness possesses the firsthand knowledge."); Wright & Gold, supra § 6022 ("[T]he testimony is excluded only if, as a matter of law, no juror could reasonably conclude that the witness perceived the facts to which she testifies.").
Accordingly, if a rational juror could conclude based on a witness's testimony that he or she has personal knowledge of a fact, the witness may testify about that fact. If, however, the witness merely has personal knowledge of an out-of-court statement offered to prove the fact asserted in that statement — but not the underlying fact — then his or her testimony must comply with the hearsay rule. See Fed. R.Evid. 602 advisory committee's notes (1972) (observing that Rule 602 "does not govern the situation of a witness who testifies to a hearsay statement as such, if he has personal knowledge of the making of the statement" because the rule governing hearsay "would be applicable"). Under that rule, "hearsay" is admissible only if permitted by a "federal statute," an exception
Agent Knoll testified he was personally involved in processing Mr. Valenzuela-Carrillo and the other undocumented alien found in Mr. Cabral's vehicle. The only time he used the immigration file was to refresh his recollection of their names. When asked what happened to Mr. Valenzuela-Carrillo, Agent Knoll responded "[w]e called your office" and "we prosecuted him for entering the country illegally." ROA, Vol. IV at 358 (emphasis added). In light of this first-person testimony, a reasonable jury could conclude he was personally involved in Mr. Valenzuela-Carrillo's successful prosecution for illegal reentry, which by definition is sufficient to establish that Mr. Valenzuela-Carrillo was not a legal resident
Ms. Gutierrez objected generally to Agent Knoll's lack of personal knowledge of Mr. Valenzuela-Carrillo's immigration status but declined to elicit testimony on cross-examination to support this objection. See United States v. Rose, 587 F.3d 695, 701 n. 3 (5th Cir.2009) ("Rose's cross-examination of Lopez focused exclusively on the calibration of the testing equipment; it did not probe whether Lopez was referring to the lab's procedures generally or whether she had personal knowledge of the tests performed in this case."). In the absence of any evidence to the contrary, Agent Knoll's testimony was sufficient to support a finding under Rule 602 that he personally observed Mr. Valenzuela-Carrillo's successful prosecution for illegal reentry. See United States v. Davis, 792 F.2d 1299, 1304 (5th Cir.1986) ("There is nothing in the record to suggest that Anderson did not, or even likely did not, have such personal knowledge. Davis had ample opportunity to cross-examine Anderson, or to take him on voire dire, to establish any lack of personal knowledge or opportunity for same, and he could have requested that this be done out of the presence of the jury. But he chose not to do any of this.").
In light of the foregoing and the deference we must pay to a district court's evidentiary rulings on hearsay objections, we conclude the district court did not abuse its discretion in determining that Agent Knoll's testimony did not introduce hearsay.
Ms. Gutierrez argues Agent Knoll's testimony about Mr. Valenzuela-Carrillo's immigration status introduced statements from his immigration file in violation of the Confrontation Clause. The Sixth Amendment provides that "[i]n all criminal prosecutions, the accused shall enjoy the right... to be confronted with the witnesses against him." U.S. Const. amend. VI. In Crawford v. Washington, 541 U.S. 36, 124 S.Ct. 1354, 158 L.Ed.2d 177 (2004), the Supreme Court held that the Confrontation Clause bars the "admission of testimonial statements of a witness who did not appear at trial unless he was unavailable to testify, and the defendant had had a prior opportunity for cross-examination." Id. at 53-54, 124 S.Ct. 1354. This holding applies only if the witness did not "appear at trial." Id. at 53, 124 S.Ct. 1354.
Here, Agent Knoll did appear at trial. And as discussed above, the record supports a finding that Agent Knoll's testimony about Mr. Valenzuela-Carrillo's immigration status derived from his own observations — not those of any out-of-court declarant. Because Ms. Gutierrez's counsel had a full opportunity to cross-examine Agent Knoll about these observations, no Confrontation Clause violation occurred. See id. at 60 n. 9, 124 S.Ct. 1354 ("The Clause does not bar admission of a statement so long as the declarant is present at trial to defend or explain it."); see also United States v. Turner, 709 F.3d 1187, 1191 (7th Cir.2013) ("Block's testimony on these points, which were within his personal knowledge, posed no Confrontation Clause problem.").
We affirm the district court's evidentiary rulings regarding Agent Knoll's testimony on Mr. Valenzuela-Carrillo's immigration status. The district court did not abuse its discretion by admitting the testimony.
Before trial, the Government notified the defendants and the court of its intent to elicit expert testimony from Agent Knoll about the alien smuggling trade. Mr. Cabral (joined by Ms. Gutierrez) moved in limine to exclude Agent Knoll's proffered expert testimony on several grounds. The district court denied the motion, reasoning that Agent Knoll was qualified as an expert to provide opinion testimony based on his extensive experience as a senior border patrol agent, and this testimony would be both reliable and helpful to the jury.
At trial, Agent Knoll provided the following expert testimony over Ms. Gutierrez's objection:
ROA, Vol. IV at 358-60 (emphasis added).
"We review de novo whether the district court applied the proper standard in deciding to admit or exclude expert testimony." United States v. Garcia, 635 F.3d 472, 476 (10th Cir.2011) (quotations omitted). "If the district court applied the correct legal standard, we then review the manner in which the court performed its gatekeeping role, deciding whether to admit or exclude testimony, for abuse of discretion." Id. We may reverse only if the district court's ruling is "arbitrary, capricious, whimsical or manifestly unreasonable or when we are convinced that the district court made a clear error of judgment or exceeded the bounds of
Federal Rule of Evidence 702 establishes several requirements that must be met before presenting expert testimony. Before considering whether an expert's testimony is reliable or helpful to the jury, "the district court generally must first determine whether the expert is qualified `by knowledge, skill, experience, training, or education' to render an opinion." United States v. Nacchio, 555 F.3d 1234, 1241 (10th Cir.2009) (en banc) (quoting Fed.R.Evid. 702). In this case, however, we need not consider whether Agent Knoll was qualified to render an opinion because Ms. Gutierrez challenges the district court's admission of his expert testimony on helpfulness grounds alone.
Under Rule 702(a), a witness qualified as an expert may "testify in the form of an opinion" if the "expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue." Fed.R.Evid. 702(a). This "condition goes primarily to relevance" because "[e]xpert testimony which does not relate to any issue in the case is not relevant and, ergo, non-helpful." Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 591, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993) (quotations omitted).
"In assessing whether testimony will assist the trier of fact, district courts consider several factors, including whether the testimony `is within the juror's common knowledge and experience,' and `whether it will usurp the juror's role of evaluating a witness's credibility.'" Garcia, 635 F.3d at 476-77 (quoting United States v. Rodriguez — Felix, 450 F.3d 1117, 1123 (10th Cir.2006) (footnote omitted)). In doing so, "courts must conduct a `common-sense inquiry' into whether a juror would be able to understand certain evidence without specialized knowledge." Id. at 477 (quoting United States v. Becker, 230 F.3d 1224, 1231 (10th Cir.2000)).
"Doubts about whether an expert's testimony will be useful should generally be resolved in favor of admissibility unless there are strong factors such as time or surprise favoring exclusions. The jury is intelligent enough to ignore what is unhelpful in its deliberations." Robinson v. Missouri Pacific R. Co., 16 F.3d 1083, 1090 (10th Cir.1994) (quotations omitted). Ultimately, therefore, expert testimony is admissible under Rule 702(a) "if it will simply help the trier of fact to understand the facts already in the record, even if all it does is put those facts in context." 4 Jack B. Weinstein & Margaret A. Berger, Weinstein's Federal Evidence § 702.03[1] (Joseph M. McLaughlin, ed., Matthew Bender, 2d ed.2014) (footnote omitted).
"Because the average juror is often innocent of the ways of the criminal underworld, expert testimony is allowed... to provide jurors a context for the actions of defendants." Garcia, 635 F.3d at 477. For example, "we routinely allow law enforcement experts with `other specialized knowledge' to opine as to the means and methods of the narcotics trade." Id. (quoting Fed.R.Evid. 702). Analogizing to this example, we also have allowed expert testimony on firearm straw purchases and gang operations. See, e.g., id. ("By analogy, expert testimony that assists jurors in distinguishing the actual purchaser of a firearm from a straw buyer is also relevant. The average juror is as likely to be unaware of the dynamics of the illicit arms trade as of the trade in narcotics."); United States v. Kamahele, 748 F.3d 984, 998 (10th Cir.2014) (allowing expert testimony on gang's "structure, insignia,
Ms. Gutierrez argues Agent Knoll's testimony was not helpful to the trier of fact and was therefore inadmissible under Rule 702(a).
First, Agent Knoll's testimony about the alien smuggling trade generally was permissible under Rule 702(a). He provided information about how smuggling operations work, why crossing a Border Patrol interior checkpoint is important, and the difficulty of apprehending an undocumented alien the further he or she moves away from the border. The average juror is unlikely to be aware of these details.
Although the Tenth Circuit appears not to have addressed whether expert testimony on alien smuggling and border patrol enforcement is "helpful" to the jury, other circuits have held that expert testimony on alien smuggling may assist the trier of fact in a related criminal prosecution. See, e.g., United States v. Montes-Salas, 669 F.3d 240, 250 (5th Cir.2012) ("The average juror may not be aware that illegal alien traffickers use `multiple bailouts' and `stash houses' and is likely unfamiliar with the different roles of guides, drivers, and recruiters in an illegal alien trafficking operation."); United States v. Mejia-Luna, 562 F.3d 1215, 1219 (9th Cir.2009) ("The testimony assisted the jury in understanding alien smuggling schemes, their operational framework, and Mejia-Luna's particular role as a `load' driver in the operation."). We see no reason to deviate from this approach, particularly in light of our conclusions in previous cases that expert testimony can help the jury better understand gang activity as well as the illicit drug and firearms trade. See Kamahele, 748 F.3d at 997-98; Archuleta, 737 F.3d at 1297; Garcia, 635 F.3d at 477 ("The average juror is as likely to be unaware of the dynamics of the illicit arms trade as of the trade in narcotics.").
Accordingly, the district court did not abuse its discretion in admitting Agent Knoll's expert testimony. We therefore affirm on this issue.
Before trial, the Government gave notice that it would refer to its two confidential informants by pseudonym because these "alias[es] are necessary to protect the witnesses from potential retaliation." ROA, Vol. I at 79. Although Ms. Gutierrez did not respond, she objected "to the whole notion of having anonymous witnesses" during the pre-trial conference. ROA, Vol. IV at 73. The district court overruled her objection.
The Government provided the defense with each witness's criminal history, compensation records reflecting how much money each had received working for the FBI, and immigration status. The Government did not, however, inform defense counsel of the informants' true identities.
At trial, Ms. Gutierrez objected before John Smith's direct examination (outside the presence of the jury), arguing the anonymous testimony would violate the Confrontation Clause. She asserted the Government's failure to use a curtain or voice-disguising technology in the courtroom with the witnesses "belie[d] the seriousness of the risk that [the Government] propound[s]." Id. at 154. When the court asked the Government to state the basis for not providing the actual identities of its witnesses, the Government responded:
Id. at 128. After hearing this justification, the court allowed the Government to present anonymous testimony from its two confidential informants.
After the Government completed its direct examination of John Smith, defense counsel renewed his Confrontation Clause objection. When the court asked the Government whether "[t]he basis for the confidential identity was security concerns," the Government responded:
Id. at 147.
After recounting a different case involving cross-border cocaine and money laundering that resulted in the cooperating witness's decapitation, the district court overruled Ms. Gutierrez's objection. The court concluded that nothing required the Government "in this context" to "disclose the [witnesses'] true names" because the Government "identified security concerns. I don't think that — I think they're valid concerns for that [sic] these confidential informants because they've been cooperating with the government." Id. at 159; see also id. at 153-54.
During direct examination, the witnesses testified about their involvement in the sting operation and Ms. Gutierrez's role in facilitating Mr. Valenzuela-Carrillo's transportation away from the border. They further testified about the recorded conversations between themselves and Ms. Gutierrez, their unrecorded discussions with the defendant, and the exchange of money at the Albuquerque restaurant.
Ms. Gutierrez's counsel cross-examined each witness about his criminal history, compensation for cooperating with the FBI, immigration status, and ties to Mexico. Mr. Cabral's counsel elicited testimony from John Smith regarding another alien smuggling arrest that the Government failed to disclose.
We (a) first summarize the substantive legal standard governing Ms. Gutierrez's Confrontation Clause claim because it informs (b) our standard of review.
The Sixth Amendment's Confrontation Clause provides that "[i]n all criminal prosecutions, the accused shall enjoy the right... to be confronted with the witnesses against him." U.S. Const. amend. VI. The Supreme Court has identified "two broad categories" of Confrontation Clause cases. See Delaware v. Fensterer, 474 U.S. 15, 18, 106 S.Ct. 292, 88 L.Ed.2d 15 (1985) (per curiam).
"The first category reflects the [Supreme] Court's longstanding recognition that the literal right to `confront' the witness at the time of trial forms the core of the values furthered by the Confrontation Clause." Id. (quotations omitted). Because Ms. Gutierrez was able to physically confront the Government's confidential
The "second category" arises when, "although some cross-examination of a prosecution witness was allowed, the trial court did not permit defense counsel to expose to the jury the facts from which jurors, as the sole triers of fact and credibility, could appropriately draw inferences relating to the reliability of the witness." Id. at 19 (quotations omitted). Put another way, confrontation problems arise in the second category of cases when cross-examination restrictions "effectively emasculate the right of cross-examination itself." Id. (quoting Smith v. Illinois, 390 U.S. 129, 131, 88 S.Ct. 748, 19 L.Ed.2d 956 (1968)).
In Smith v. Illinois, 390 U.S. 129, 88 S.Ct. 748, 19 L.Ed.2d 956 (1968), the Supreme Court held that the right of confrontation necessarily includes the right to "ask the witness who he is and where he lives" because this is "the very starting point in exposing falsehood and bringing out the truth through cross-examination" when "the credibility of a witness is in issue." Id. at 131, 88 S.Ct. 748 (footnotes and quotations omitted). At the same time, the Court reiterated lower courts' "duty to protect [witnesses] from questions which go beyond the bounds of proper cross-examination merely to harass, annoy or humiliate [them]." Id. at 133, 88 S.Ct. 748 (quotations omitted). Justice White (joined by Justice Marshall) concurred, observing he "would place in the same category" as questions tending to harass, annoy, or humiliate "those inquiries which tend to endanger the personal safety of the witness." Id. at 133-34, 88 S.Ct. 748 (White, J., concurring).
Following Justice White's lead, federal courts, including this circuit, "have interpreted the Supreme Court's language concerning harassment, annoyance or humiliation to include exposure of the witness to danger." United States v. Smaldone, 484 F.2d 311, 318 (10th Cir.1973) (citing cases from the Fifth and Seventh Circuits and "the cases cited therein"). In Smaldone, for example, we affirmed the district court's refusal to allow cross-examination about a government informant's "present address" because "there existed at least some problem of protection." Id. at 318. Since Smaldone, neither the Supreme Court nor the Tenth Circuit has squarely addressed the question presented here — whether or under what circumstances government witnesses may testify anonymously without violating the defendant's right of confrontation.
Although we have not articulated a precise standard for evaluating anonymous testimony, several other circuits have. These courts evaluate Confrontation Clause claims based on anonymous testimony by asking (i) whether the government has demonstrated a threat and if so, (ii) whether anonymous testimony deprived the defendant of an opportunity for effective cross-examination. We briefly summarize these factors before applying them to Ms. Gutierrez's case.
First, the government must demonstrate a threat to the witness's personal safety. See, e.g., United States v. Ramos-Cruz, 667 F.3d 487, 500 (4th Cir.2012) ("When the government seeks to withhold a witness's true name, address, or place of employment, it bears the burden of demonstrating that `the threat to the witness is actual and not a result of conjecture.'") (quoting United States v. Palermo, 410 F.2d 468, 472 (7th Cir.1969)); Caldwell v. Minnesota, 536 F.2d 272, 274 (8th Cir. 1976) (affirming nondisclosure of witness's address and place of employment in part because the record "contain[ed] evidence that disclosure ... might have posed a
This threat need not come from the defendants themselves. See United States v. Celis, 608 F.3d 818, 832 (D.C.Cir. 2010) ("The appropriateness of using pseudonyms to protect witnesses does not depend on whether the threat to the witness comes directly from a defendant or from another source."); accord Ramos-Cruz, 667 F.3d at 501 (citing Celis with approval). But "a generalized statement" about danger — such as "anyone who testifies against one of [a gang's] members faces danger from [that gang]" — "would be insufficient to show that a threat against a witness was `actual and not a result of conjecture.'" Ramos-Cruz, 667 F.3d at 501 (quoting Palermo, 410 F.2d at 472); see also United States v. Lawler, 413 F.2d 622, 627 n. 4 (7th Cir.1969) (disapproving of the prosecution's "unsubstantiated reference to the possible danger to the witness's safety").
In Smaldone, we accepted the government's justification for preventing defense counsel from eliciting the present address of the government's witness. Before trial, the government informed the trial court "that the witness had been relocated because there existed `an apparent danger to [his] physical health and well-being.'" 484 F.2d at 319. It also "notified counsel for the defendant by letter that `substantial reason to fear for his safety has been shown and he ([the witness]) has requested that his present whereabouts not be divulged.'" Id. Moreover, we observed "[t]he defendant admittedly had involvement in gambling and at the very least the court could have believed that revealing the address of the witness would stir apprehension in the mind of the witness and thereby affect his testimony." Id.
Second, if the government demonstrates a threat, courts then consider whether the lack of the witness's identifying information deprived the defendant of an opportunity for effective cross-examination. See Ramos-Cruz, 667 F.3d at 500 ("If the government makes a showing of an actual threat, the district court still has discretion to review relevant information and determine whether disclosure of the witness's identifying information is necessary to allow effective cross-examination." (citing Palermo, 410 F.2d at 472)); United States v. El-Mezain, 664 F.3d 467, 492-93 (5th Cir.2011) (allowing anonymous testimony because it did not deprive defendant of an opportunity for effective cross-examination); United States v. Mohamed, 727 F.3d 832, 838 (8th Cir.2013) ("Smith requires reversal only where the lack of a witness's name and address denies a defendant an opportunity to effectively cross-examine a witness." (quotations omitted)).
"Effective cross-examination only requires that the trial judge not limit the scope of cross-examination so that it prevents
"Other circuits consider various factors when determining whether a witness's use of a pseudonym denied a defendant the opportunity to effectively cross-examine the witness." Mohamed, 727 F.3d at 838. "These factors include whether the defendant was informed of the witness's real name before the witness testified, Siegfriedt v. Fair, 982 F.2d 14, 18 (1st Cir. 1992), and whether the defendant was able to cross-examine the witness on his or her background and/or credentials, Clark v. Ricketts, 958 F.2d 851, 854-55 (9th Cir. 1991)." Mohamed, 727 F.3d at 838.
The Government may provide an opportunity for effective cross-examination by disclosing a witness's real name to defense counsel while the court still allows the witness to testify under an alias, but this is not the only means to do so. Rather, courts consider disclosure of a witness's real name as part of a balancing inquiry when applying Smith's exhortation to provide defense counsel with "the opportunity to place the witness in his proper setting and put the weight of his testimony and his credibility to a test." Smith, 390 U.S. at 132, 88 S.Ct. 748 (quotations omitted); see Mohamed, 727 F.3d at 838 ("Smith does not per se require a new trial merely because the district court sustained an objection to a question seeking to elicit [the witness's] address." (quotations omitted)); El-Mezain, 664 F.3d at 491 ("There is no fixed rule with respect to disclosure." (quotations omitted)); Celis, 608 F.3d at 830 (observing that the Supreme Court "has addressed such disclosure issues on a case-by-case basis"); United States v. Machado-Erazo, 951 F.Supp.2d 148, 157 (D.D.C. 2013) ("Celis cautions that courts must make careful factual findings, doing everything possible to make sure that defendants receive the information that they can, but it does not create a per se rule of disclosure."); United States v. Rangel, 534 F.2d 147, 148 (9th Cir.1976) (observing that Smith "does not establish a rigid rule of disclosure, but rather discusses disclosure against a background of factors weighing conversely, such as personal safety of the witness" (quotations omitted)); see also Smaldone, 484 F.2d at 318 (observing that Smith's requirement that a defendant be allowed to cross-examine a witness about his or her address is not "invariable," particularly where it would expose "the witness to danger").
Even when the government has not disclosed witnesses' true identities to defense counsel, several circuits have concluded defendants were not deprived of an opportunity for effective cross-examination. In Ramos-Cruz, for example, the Fourth Circuit approved of anonymous testimony in part because the government "disclosed the substance of the testimony the two witnesses would provide at trial." 667 F.3d at 501.
Accordingly, if the government provides defense counsel with sufficient background information on the anonymous witness (e.g., criminal history, nationality, etc.), then withholding the witness's name or address does not necessarily deprive the defendant of an opportunity for effective cross-examination, which is the touchstone of a Confrontation Clause inquiry. See Tapia v. Tansy, 926 F.2d 1554, 1559 (10th Cir.1991) ("[T]he Confrontation Clause ensures the defendant the opportunity to engage in `effective cross-examination' of the witnesses against him, but it does not include `the power to require the disclosure of any and all information that might be useful in contradicting unfavorable testimony.'" (citations omitted) (quoting Pennsylvania v. Ritchie, 480 U.S. 39, 51, 53, 107 S.Ct. 989, 94 L.Ed.2d 40 (1987) (plurality op.))); see also United States v. Mullins, 613 F.3d 1273, 1283 (10th Cir. 2010) ("The touchstone for whether the Confrontation Clause has been satisfied is whether the jury had sufficient information to make a discriminating appraisal of the witness' motives and bias." (quotations omitted)); Lisa I. Karsai, You Can't Give My Name: Rethinking Witness Anonymity in Light of the United States and British Experience, 79 Tenn. L.Rev. 29, 91 (2011) ("When a witness's identity is not likely to lead to impeachment material beyond that which has already been disclosed to the defendant, the ability to effectively cross-examine the witness is unlikely to be impaired by an anonymity order.").
"We review de novo whether cross-examination restrictions violate a defendant's Sixth Amendment right to confrontation." United States v. Geames, 427 F.3d 1333, 1337 (10th Cir.2005); accord United States v. Contreras, 536 F.3d 1167, 1172 (10th Cir.2008). We review the district court's subsidiary assessment of the threat to a witness's safety, however, for abuse of discretion. See United States v. Cruz, 680 F.3d 1261, 1263 (10th Cir.2012) ("We review the denial of a motion for disclosure of a confidential informant's identity for abuse of discretion."); United States v. Moralez, 908 F.2d 565, 567 (10th Cir.1990) (same).
Ms. Gutierrez argues the district court violated the Confrontation Clause in permitting the anonymous testimony because (a) the Government failed to justify secrecy and (b) the witnesses' anonymity deprived her of an effective opportunity to cross-examine them. The Government disputes these assertions and also argues (c) any error is harmless beyond a reasonable doubt.
First, we agree the Government failed to make an adequate showing to justify secrecy. The district court abused its discretion in concluding otherwise. As discussed above, circuits affirming the use of anonymous testimony have done so in part because the Government produced specific evidence of a threat. In Celis, for example, the D.C. Circuit approved a protective order preventing disclosure of the witnesses' identities in part because "the government presented evidence that in Colombia the FARC[
Similarly, in Ramos-Cruz, the witnesses "specifically explained" to the district court in sealed ex parte proceedings "the heightened level of danger to which El Salvadorians who testify against MS-13[
In El-Mezain, the Fifth Circuit concluded "there was a serious and clear need to protect the true identities of [Israeli anonymous witnesses] Avi and Major Lior" in part because "[t]he Government showed that Hamas and other terrorist organizations seek out the true identities of [Israeli Security Agency] agents and their families and publish descriptions of ISA officers on websites so that they can be targeted." 664 F.3d at 492.
Although the Government may well have been able to present at least some evidence establishing a threat to these witnesses, its efforts were minimal. It failed on the record before us to demonstrate one. See Ramos-Cruz, 667 F.3d at 500; see also Palermo, 410 F.2d at 473 (reversing because "[w]hile there was an adequate showing of a threat to the life of [one witness], there was no showing as to [the other witness]" and "[i]n neither case was the relevant information disclosed to the trial judge in order that he could make an informed decision"); Lawler, 413 F.2d at 627 n.4 (finding defendant was not prejudiced by cross-examination limitation but "plac[ing] no special reliance on the unsubstantiated reference to the possible danger to the witness's safety").
We therefore conclude the district court abused its discretion in determining the Government adequately justified secrecy. See Clyma v. Sunoco, Inc., 594 F.3d 777, 783 (10th Cir.2010) ("[A] `clear example of an abuse of discretion exists where the trial court fails to consider the applicable legal standard or the facts upon which the exercise of its discretionary judgment is based.'") (quoting Ohlander v. Larson, 114 F.3d 1531, 1537 (10th Cir.1997)).
Second, despite the Government's inadequate justification for secrecy, Ms. Gutierrez was not deprived of an opportunity for effective cross-examination of the Government's confidential informants.
Although the Government withheld these witnesses' true identities from the defense, Ms. Gutierrez was still able to face them before the jury. Moreover, the Government provided defense counsel with significant impeachment material on each witness, including their prior arrests, compensation schedule for cooperating with the DEA, and immigration status. Armed with this material, defense counsel questioned John Smith about: his prior charge for transporting aliens, which the Government dismissed in exchange for his cooperation; his compensation for assisting the Government, which amounted to roughly $8,000; his family ties to Chihuahua, Mexico; and his retaining his green card in exchange for cooperating. See ROA, Vol. IV at 162-68. Defense counsel also questioned James Jones regarding: his being paroled into the United States while assisting the government; his compensation for cooperating with the Government, which amounted to roughly $2,000; and his family ties to Chihuahua, Mexico. See id. at 205-12.
Although Mr. Cabral's counsel elicited testimony from John Smith about an undisclosed arrest, the Government's inadvertent failure to disclose this fact did not deprive Ms. Gutierrez of an opportunity for effective cross-examination. The Government's other disclosures provided defense counsel "the opportunity to place the witness[es] in [their] proper setting and put the weight of [their] testimony and [their] credibility to a test." Smith, 390 U.S. at 132, 88 S.Ct. 748. Defense counsel's cross-examination regarding the other disclosures provided by the Government gave the jury "sufficient information to make a `discriminating appraisal' of the relevant issue," Cooper, 967 F.2d at 402 (quotations omitted) — here, the witnesses' credibility. See United States v. Alaniz, 726 F.3d 586, 611 (5th Cir.2013) (affirming restrictions on anonymous testimony because "cross-examination provided the jury with ample insight into CS1 and CS2's respective associations and criminal pasts, and possibly self-interested motivations for cooperating with the government."); El-Mezain, 664 F.3d at 493 (concluding that "although the defense could not verify the witnesses' credentials, the district court correctly observed that the defendants had access to significant information regarding the witnesses' employment, nationalities, and backgrounds in order to conduct meaningful cross-examination"); United States v. Olson, 978 F.2d 1472, 1477 (7th Cir.1992) ("Notable in this case is the ample opportunity defendants had to impeach Fessler's testimony. They were able to bring out a prior felony conviction, a misdemeanor conviction for fraud, perjury, and receipt of payment for testimony." (footnote omitted)).
In light of the foregoing, the Government's refusal to disclose the witnesses' true identities did not deprive Ms. Gutierrez of an opportunity for effective cross-examination. See Van Arsdall, 475 U.S. at 679, 106 S.Ct. 1431 ("[T]he Confrontation Clause guarantees an opportunity for effective cross-examination, not cross-examination that is effective in whatever way, and to whatever extent, the defense might wish." (quoting Fensterer, 474 U.S. at 20, 106 S.Ct. 292)); United States v. McHorse, 179 F.3d 889, 900 (10th Cir.1999) ("[T]he demands of the Confrontation Clause are satisfied where a defendant has the opportunity to reveal weaknesses in the witness'
Despite the Government's failure to demonstrate a threat to its witnesses' safety, we conclude this error was harmless. The Government's disclosures provided an opportunity for effective cross-examination, and the remaining evidence against Ms. Gutierrez established substantial corroboration. See Ellis, 468 F.2d at 639 ("While the procedures suggested in United States v. Palermo, 410 F.2d 468, 472 (7th Cir.1969), should ordinarily be followed in such circumstances, we conclude, in view of the marginal significance of the witness's testimony in this case, that no prejudice to the defendant can be shown."); Lawler, 413 F.2d at 627 ("In view of the extensive cross-examination of [the witness] permitted defendant's counsel and the fact that the bulk of the testimony damaging to [the defendant] was presented by the narcotics agents, we hold that on the facts of the present case defendant suffered no prejudicial denial of the right to confrontation and effective cross-examination.").
"Violations of the Confrontation Clause are subject to harmless error analysis, under which the beneficiary of a constitutional error must prove beyond a reasonable doubt that the error complained of did not contribute to the guilty verdict." United States v. Chavez, 481 F.3d 1274, 1277 (10th Cir.2007) (quotations omitted). "We review the record de novo." Id. "The correct inquiry is whether, assuming that the damaging potential of the cross-examination were fully realized, a reviewing court might nonetheless say that the error was harmless beyond a reasonable doubt." Van Arsdall, 475 U.S. at 684, 106 S.Ct. 1431.
In conducting this inquiry, we "consider various factors, including `the importance of the witness's testimony in the prosecution's case, whether the testimony was cumulative, the presence or absence of evidence corroborating or contradicting the testimony of the witness on material points, the extent of cross-examination otherwise permitted, and, of course, the overall strength of the prosecution's case.'" United States v. Woodard, 699 F.3d 1188, 1198 (10th Cir.2012) (quoting Van Arsdall, 475 U.S. at 684, 106 S.Ct. 1431).
Here, after carefully reviewing the record, we conclude these factors demonstrate the error in failing to require a greater showing of threat was harmless beyond a reasonable doubt. First, although Mr. Smith and Mr. Jones provided a fact-based narrative of their conversations with the defendants and their trip
Second, much of Mr. Smith and Mr. Jones's testimony was cumulative of the Government's own surveillance observations. See also United States v. Williams, 576 F.3d 1149, 1163 (10th Cir.2009) (finding limitation on cross-examination harmless in part because "overlapping and equally damaging testimony was provided by other witnesses")
Third, on every material point of Mr. Smith and Mr. Jones's testimony, the Government presented considerable corroborating evidence. Agent John Wardle testified about the FBI and Border Patrol's round-the-clock surveillance of Mr. Smith and Mr. Jones during their transfer of Mr. Valenzuela-Carrillo from El Paso to Albuquerque by way of Las Cruces. See ROA, Vol. IV at 247-48, 257. The Government introduced recorded telephone conversations between Ms. Gutierrez and Mr. Smith and between Mr. Cabral and Mr. Smith in which they discussed logistics and the terms of the deal. See ROA, Vol. IV at 232, 238-46, 249-52, 254-56. The Government introduced a receipt for $1,500 from the Walmart MoneyCenter bearing Ms. Gutierrez's name and played video showing Ms. Gutierrez at the Walmart MoneyCenter shortly before she joined the rest of the group outside Little Anita's, the Albuquerque restaurant where Mr. Smith handed off Mr. Valenzuela-Carrillo to Mr. Cabral in exchange for $1,100 from Ms. Gutierrez. See id. at 227-28 (authenticating video), 271-75 (providing commentary). The Government played a video recording of the Little Anita's meeting between Ms. Gutierrez, Mr. Smith, and Mr. Cabral, and Agent Brian Regan testified that he received $1,100 cash from Mr. Smith after this transaction. See id. at 124-25 (laying foundation for video), 221 (Agent Regan's testimony), 257-62 (discussing surveillance of Little Anita's and playing video for the jury). Moreover, nothing in the record contradicts the material testimony of Mr. Smith and Mr. Jones.
Fourth, as discussed above, the district court permitted substantial cross-examination of Mr. Smith and Mr. Jones based on the Government's disclosures, including their criminal history, compensation, and incentive to cooperate with the Government. This questioning allowed Ms. Gutierrez an opportunity to undermine their credibility despite her inability to ask about their true identities. See Mullins, 613 F.3d at 1283 (affirming cross-examination limitation in part because the defendant "was allowed extensive cross-examination into [the witness's] cooperation agreement with the government"); United States v. Oliver, 278 F.3d 1035, 1041 (10th Cir.2001) (affirming cross-examination limitation in part because the defendant "was able to elicit that [the witness] had an extensive criminal history, a serious drug problem, a history of using fake names and identifications, and a record of failing to appear in court after signing promises to do so"); Brown, 482 F.2d at 1229 (affirming
Fifth, and most important, the overall strength of the Government's case rendered any error harmless. See Dickerson v. State, 957 N.E.2d 1055, 1059 (Ind.Ct. App.2011) ("The State's case against Dickerson was strong, and the testimony of the confidential informant played only a part in Dickerson's convictions. The buys were audio and video recorded and officers maintained visual surveillance during the first controlled buy and arrested Dickerson immediately following the second, finding him in possession of the buy money and other drugs."). In addition to the substantial surveillance evidence discussed above, the Government introduced Ms. Gutierrez's post-arrest confession. When Agent Wardle asked Ms. Gutierrez "about the events that gave rise to the charge in the Indictment," she "admitted that she had arranged for the alien that day at the Little Anita's to be transported to Denver." ROA, Vol. IV at 298.
In light of the corroborating evidence provided by the Government, the extent of cross-examination permitted, and the overall strength of the Government's case, which included Ms. Gutierrez's admission of guilt, we conclude the Government met its burden to prove the error harmless beyond a reasonable doubt. See United States v. Toles, 297 F.3d 959, 968 (10th Cir.2002) ("Given Toles' and Morris' confessions, as well as the corroborating evidence of the other testifying witnesses, this court is satisfied that the limitation on the cross-examination of Harris was harmless beyond a reasonable doubt.").
We affirm on this issue because, although the Government's showing of threat was inadequate, the Government's disclosures gave Ms. Gutierrez an opportunity for effective cross-examination, and any error was harmless beyond a reasonable doubt.
In sum, we affirm Ms. Gutierrez's conviction because: (1) Agent Knoll's fact testimony did not violate the Federal Rules of Evidence or the Confrontation Clause; (2) his expert testimony on alien smuggling was helpful to the jury under Rule 702(a); and (3) the district court's error in permitting the Government's confidential informants to testify anonymously without a sufficient showing of threat did not deprive her of an opportunity for effective cross-examination and was harmless beyond a reasonable doubt.
Additionally, nothing indicates Agent Knoll's testimony that Mr. Valenzuela-Carrillo ultimately "was removed to Mexico," ROA, Vol. IV at 358, was not based on his own personal observations. Regardless, because Mr. Valenzuela-Carrillo's successful prosecution for illegal reentry was enough to establish his unlawful presence in the country, it was not necessary for Agent Knoll to attest to Mr. Valenzuela-Carrillo's physical removal from the United States or any formal proceedings following the successful illegal reentry prosecution.
Her brief, however, neither cites Rule 704(b) nor develops this argument any further. We therefore consider it waived. See Fed. R.App. P. 28(a)(8)(A) (requiring the appellant to set forth "appellant's contentions and reasons for them, with citations to the authorities and part of the record on which the appellant relies" (emphasis added)); Arizona Pub. Serv. Co. v. U.S. E.P.A., 562 F.3d 1116, 1130 (10th Cir.2009) ("We need not address unsupported, conclusory arguments."); Pignanelli v. Pueblo Sch. Dist. No. 60, 540 F.3d 1213, 1217 (10th Cir.2008) ("Because Pignanelli has not directed us to any legal authority or record evidence supporting a claim for relief under the Due Process Clause of the Fourteenth Amendment, her appeal on this ground must fail.").
Even if we were to consider this argument, we would reject it. Agent Knoll's general testimony that, in his experience, movement away from the border furthers an undocumented alien's illegal presence in the country, did not discuss Ms. Gutierrez's mental state or even the specific facts of her case. It therefore left for the jury the ultimate inference on her intent. See United States v. Richard, 969 F.2d 849, 854-55 (10th Cir.1992) ("Rule 704(b) only prevents experts from expressly stating the final conclusion or inference as to a defendant's actual mental state. The rule does not prevent the expert from testifying to facts or opinions from which the jury could conclude or infer the defendant had the requisite mental state.").
We disagree. At the pre-trial conference, defense counsel objected to the "whole notion" of having anonymous witnesses. ROA, Vol. IV at 73. Later at trial, defense counsel objected again on Confrontation Clause grounds and argued the open court testimony of the Government's witnesses "belie[d] the seriousness of the risk that [the Government] propound[s]." Id. at 154. These objections, while perhaps not as clear as they could have been, were nonetheless adequate to preserve this claim of error for appeal.
