                              ORDER AND JUDGMENT *


Before BRISCOE, MURPHY, and O’BRIEN, Circuit Judges.


      Driving north from the border in the remote “bootheel” section of

southwestern New Mexico, Luis Edgar Montes-Ramos was pulled over by a

deputy sheriff because his temporary registration tag was not properly affixed to

his vehicle or legible. While waiting for Montes-Ramos to produce his driver’s

license, the deputy noticed a blanket in the backseat, covering what appeared to

be large items. He saw a five-inch circular section of burlap protruding from

underneath the blanket. Based on his observation of burlap, his law enforcement

experience, and the location of the stop (along a known drug smuggling route),

the deputy suspected Montes-Ramos was trafficking marijuana. To confirm his

suspicion, he leaned his head into the open window very slightly and sniffed. He

smelled marijuana and arrested Montes-Ramos. At the police station, 96

kilograms of marijuana were found in the vehicle. Montes-Ramos appeals from a

partial denial of his motion to suppress. Even though the deputy’s minimal

intrusion into the vehicle to effectuate the sniff was reasonable under the

circumstances, we are obliged to reverse. 1

                                   I. BACKGROUND

      The facts are not in dispute. Around 11:00 a.m. on February 8, 2006,

Montes-Ramos was driving northbound on New Mexico Highway 80,

approximately forty miles north of the border and thirty miles south of Lordsburg,

New Mexico. 2 Hidalgo County Sheriff’s Deputy Robert Rodriguez was in his

patrol car on the shoulder of the southbound side of Highway 80, checking traffic

by radar. Rodriguez observed a gold sedan traveling northbound with no license

plate; it had instead a piece of paper where the license plate is generally placed.

The paper was “flapping in the wind” and was not legible. (R. Vol. III at 22.)

      1
          We exercise jurisdiction pursuant to 28 U.S.C. § 1291.
      2
         Highway 80 runs northeast from the border town of Douglas, Arizona, through
the sparsely populated “bootheel” section of southwestern New Mexico before
intersecting Interstate 10.

                                            -2-
Rodriguez pulled onto the highway, made a U-turn, and signaled for the driver of

the gold sedan – Montes-Ramos – to pull over. When Montes-Ramos pulled over,

Rodriguez approached the vehicle on the passenger side. At that point, Rodriguez

realized the piece of paper appeared to be a valid Arizona temporary registration

tag. However, instead of being affixed inside the back rear window, as normally

required by New Mexico law, the tag was encased in a clear plastic envelope,

only the top of which was attached to the car’s license plate holder. The car’s

windows were neither tinted nor dirty, and the tag would have been clearly visible

if affixed to the inside rear window.

      Though he did not intend to issue a ticket, Rodriguez advised Montes-

Ramos in Spanish that his tag was placed in the wrong location and asked him to

produce his driver’s license. While Montes-Ramos was looking for his license,

Rodriguez observed some large items in the backseat, covered by a leopard-print

blanket. A five-inch circular section of burlap was visible underneath the blanket.

At the hearing on Montes-Ramos’ motion to suppress, Deputy Rodriguez testified

“[w]hat [he] observed was consistent with the transportation of illegal contraband

into the United States.” (Id. at 14.) He explained drugs are often bundled into

tight bricks and wrapped with burlap cloth. When asked whether the bundles he

observed “appear[ed] consistent with burlap packaging of produce like onions or

chile,” he answered: “No.” (Id. at 47.) He testified that during his almost

seventeen years in law enforcement, he had been involved in approximately “one

                                        -3-
dozen” drug-related investigations, of which “[a]pproximately two” involved the

seizure of marijuana packaged in burlap. 3 (Id. at 15.)

       To confirm his suspicion that Montes-Ramos was transporting marijuana,

Deputy Rodriguez “placed [his] nose – [his] face inside the [front passenger-side]

door approximately two inches.” (Id. at 16.) The sole purpose of the sniff was to

determine whether there was marijuana in the backseat. After leaning into the

car, Rodriguez detected a strong odor of marijuana. He drew his pistol, ordered

Montes-Ramos out of the vehicle, handcuffed him, and placed him under arrest.

Prior to being read his Miranda 4 rights, Montes-Ramos admitted he was

transporting marijuana. While waiting for backup to arrive, Rodriguez removed

the blanket from the backseat, pierced one of the bundles, and observed a green

leafy substance consistent with marijuana. At the station, a complete search of

the vehicle revealed five burlap bags containing 96 kilograms (approximately 211

pounds) of marijuana.

       Montes-Ramos was indicted with possession with intent to distribute fifty

kilograms and more of marijuana in violation of 21 U.S.C. §§ 841(a)(1), (b)(1)(C)

and 18 U.S.C. § 2. He moved to suppress the evidence found in the vehicle and

the statements he made to the police. The district court granted the motion as to

the roadside statement because Montes-Ramos made it prior to being advised per

the requirements of Miranda. The court denied the motion as to all other

statements and evidence. It concluded the traffic stop was justified at its

inception and was not unreasonably broad. The court considered the sniff to be a

search, but held it did not violate the Fourth Amendment because it was supported

by reasonable and articulable suspicion and officer safety. Montes-Ramos pled

guilty to the indictment, reserving the right to appeal from the suppression

decision. He was sentenced to 21 months imprisonment. 5

                                    II. DISCUSSION

       “When reviewing the denial of a motion to suppress, we view the evidence

in the light most favorable to the government, accept the district court’s findings

of fact unless clearly erroneous, and review de novo the ultimate determination of

reasonableness under the Fourth Amendment.” United States v. Katoa, 

, 1205 (10th Cir. 2004).

       5
         At oral argument, Montes-Ramos’ counsel advised the Court that Montes-Ramos
is no longer in custody. Because he is challenging the underlying conviction, not the
sentence, Montes-Ramos’ appeal is not moot. See Fiswick v. United States, 

,
222 (1946) (holding the petitioner’s challenge of his conviction is not rendered moot by
the expiration of the underlying sentence because collateral consequences flowing from
the conviction give the petitioner “a substantial stake in the judgment of conviction which
survives the satisfaction of the sentence imposed on him”).

their persons, houses, papers, and effects, against unreasonable searches and

seizures . . . .” U.S. Const. amend. IV. “A routine traffic stop is a ‘seizure’

within the meaning of the Fourth Amendment . . . .” United States v. Ramirez,

, 1243 (10th Cir. 2007) (citation omitted), cert. denied, 

(2008). “[A] traffic stop is valid under the Fourth Amendment if the stop is

based on an observed traffic violation or if the police officer has reasonable

articulable suspicion that a traffic or equipment violation has occurred or is

occurring.” United States v. Botero-Ospina, 

, 787 (10th Cir. 1995)

(en banc).

      The initial stop of Montes-Ramos’ vehicle did not violate the Fourth

Amendment because Rodriguez observed a violation of N.M. Stat. Ann. § 66-3-

18(B), which provides:

      A . . . temporary registration permit shall be firmly affixed to the
      inside left rear window of the vehicle to which it is issued, unless
      such display presents a safety hazard or the . . . permit is not visible
      or readable from that position, in which case, the . . . permit shall be
      displayed in such a manner that it is clearly visible from the rear or
      left side of the vehicle.

Montes-Ramos was in violation of this statute because his temporary tag was not

affixed to the inside left rear window, but was instead displayed outside the

vehicle in such a manner that it was not clearly visible from the rear of the

vehicle. “[A] vehicle’s apparent failure to display some form of visible license

plate/registration tag, temporary or permanent, gives rise to a reasonable


                                          -6-
suspicion that its driver might be violating any one of the multitude of applicable

traffic and equipment regulations of the jurisdiction.” United States v. Edgerton,

, 1048 (10th Cir. 2006) (quotations omitted).

      To be reasonable, a traffic stop must not only be “justified at its inception,”

the temporary detention associated with the stop must be “reasonably related in

scope to the circumstances which justified the interference in the first place.”

(quotations omitted). Montes-Ramos argues

Deputy Rodriguez’s actions violated this second prong, relying on United States

v. McSwain, 

(10th Cir. 1994), and Edgerton. We see it differently.

      In McSwain, a state trooper stopped the defendant’s vehicle “for the sole

purpose of ensuring the validity of the vehicle’s temporary registration 

. As the trooper approached the vehicle on foot, he verified the

sticker was valid and had not expired. 

the trooper’s decision to

prolong the detention by questioning the defendant and requesting his license and

registration “exceeded the scope of the stop’s underlying justification” and

therefore violated the Fourth Amendment. 

a state trooper

stopped the defendant’s vehicle because he could not read the temporary

registration tag in the 

. Notably, “the tag was illegible not

due to any material within Defendant’s ability to control, but due to external

conditions.” 

We held “[o]nce [the trooper] was able to read the

Colorado tag and deem it unremarkable, any suspicion that defendant had violated

                                         -7-
[the Kansas statute relating to the display of license plates] dissipated . . . [and

the trooper], as a matter of courtesy, should have explained to Defendant the

reason for the initial stop and then allowed her to continue on her way without

requiring her to produce her license and registration.” 

      The troopers in McSwain and Edgerton had reasonable suspicion the

vehicles they stopped were violating the traffic laws, but their suspicion

evaporated when they determined no violations had in fact occurred. Here, by

contrast, there was an actual traffic violation – Montes-Ramos’ tag, though valid,

was not displayed in accordance with New Mexico law. Thus, Rodriguez’s

demand for Montes-Ramos’ license did not exceed the scope of the stop. This

case is more analogous to United States v. Concepcion-Ledesma, 

(10th Cir. 2006), and United States v. DeGasso, 

(10th Cir. 2004).

In Concepcion-Ledesma, we held it was reasonable for the trooper “to issue a

written warning, verify [the defendant]’s license and registration information, and

ask preliminary questions about travel plans” because the trooper saw the

defendant’s registration tag displayed in an unlawful manner, even after he

approached the 

. Similarly, in DeGasso, we upheld a

trooper’s detention of the defendant because the trooper observed a continuing

violation of state law after stopping the defendant’s 

.

We distinguished McSwain because “the violation was that the lettering on the

license plate was not ‘clearly visible,’ which remained true even after the trooper

                                           -8-
approached the truck and was able, at that point, to read it.” 

As

these cases make clear, an officer does not violate the Fourth Amendment by

requesting a driver produce his license after being stopped for a traffic violation.

B. The Sniff

      While Rodriguez was waiting for Montes-Ramos to produce his license, he

observed suspect objects in the backseat and leaned his head approximately two

inches into the car window and sniffed. Montes-Ramos contends the sniff was an

unreasonable search; the government contends the sniff was not a search, but if it

was a search, it was reasonable. We first consider whether the sniff was a search.

      1. Was It A Search?

       This Court has not previously considered whether an officer’s intentional

act of minimally intruding the air space of a lawfully stopped vehicle for an

investigatory purpose constitutes a search within the meaning of the Fourth

Amendment. It is not a simple question.

      The protections of the Fourth Amendment apply to the interior of

automobiles, at least to some extent. In New York v. Class, the Supreme Court

held an officer conducted a search within the meaning of the Fourth Amendment

when he opened a car door and reached into the interior of the vehicle to move

papers obscuring the area of the dashboard where the vehicle identification

number (VIN) is typically located. 

, 108, 115 (1986). The Court

explained: “While the interior of an automobile is not subject to the same

                                          -9-
expectations of privacy that exist with respect to one’s home, a car’s interior as a

whole is nonetheless subject to Fourth Amendment protection from unreasonable

intrusions by the police.” 

Similarly, in United States v. Ryles, the

Fifth Circuit held a trooper’s act of either opening the driver’s side door or

sticking his head inside an open window constituted a search because the officer

“intruded a space that, under most circumstances, is protected by a legitimate

expectation of privacy.” 6 

, 15 (5th Cir. 1993); see also United States

v. Stone, 

, 363 (10th Cir. 1989) (“People have a reasonable

expectation of privacy in the interiors of their automobiles . . . .”).

      In Kyllo v. United States, the Court remarked: “When the Fourth

Amendment was adopted, as now, to ‘search’ meant to look over or through for

the purpose of finding something; to explore; to examine by inspection . . . .” 

, 32 n.1 (quotations omitted). Rodriguez’s actions satisfy this definition S

he leaned his head into Montes-Ramos’ car to examine by inspection whether the

car smelled of marijuana. The fact that the intrusion was minimal does not affect

the analysis. In Kyllo, the Court explained: “[T]here is certainly no exception to

the warrant requirement for the officer who barely cracks open the front door and

sees nothing but the nonintimate rug on the vestibule 

; see

also Silverman v. United States, 

, 512 (1961) (refusing to uphold an

Amendment because it was reasonable. 

.

                                          -10-
“actual intrusion into a constitutionally protected area” despite the fact the

intrusion was “by even a fraction of an inch”). 7 Over a century ago, Justice

Bradley explained: “It may be that it is the obnoxious thing in its mildest and

least repulsive form; but illegitimate and unconstitutional practices get their first

footing in that way, namely, by silent approaches and slight deviations from legal

modes of procedure.” Boyd v. United States, 

, 635 (1886). If, as

Class instructs, the interior airspace of the car is protected, then it must be

protected from minimal intrusions as well as flagrant ones.

      The only basis we can see for concluding Rodriguez’s sniff was not a

search is by analogy to cases involving canine sniffs. In Illinois v. Caballes, the

Court held a canine sniff of the exterior of a vehicle during a lawful traffic stop

“does not rise to the level of a constitutionally cognizable infringement.” 

, 409 (2005). The Court explained:

      The legitimate expectation that information about perfectly lawful
      activity will remain private is categorically distinguishable from
      respondent’s hopes or expectations concerning the nondetection of
      contraband in the trunk of his car. A dog sniff conducted during a
      concededly lawful traffic stop that reveals no information other than
      the location of a substance that no individual has any right to possess
      does not violate the Fourth Amendment.

We are attracted by the reasoning in Caballes; but it is significant that


      7
         We recognize Kyllo and Silverman involved intrusions into the home, which is
subject to greater Fourth Amendment protection than an automobile. See 

. That said, we believe the principle that a minimal intrusion can violate the Fourth
Amendment is not limited to intrusions into the home.

                                           -11-
the dog sniff at issue there was conducted on the exterior of the car. While it

revealed information about the car’s contents, the dog did not actually intrude

into the car’s protected space. 8 Moreover, because a drug dog is trained to alert

only to the presence of drugs, its “search” will only disclose information about

the presence of certain contraband; it will reveal nothing about other (presumably

innocent) smells. Though farfetched, Rodriguez’s sniff could have revealed

information about Montes-Ramos’ private, lawful activities – the perfume of a

recently departed passenger, a recently consumed lunch, a wet dog – as well as

illegal activities – contraband or perhaps a decomposing body.

       We conclude a police officer’s intentional act of intruding a vehicle’s air

space, even if by only a few inches, constitutes a search within the meaning of the

Fourth Amendment. It would be different if Rodriguez had smelled marijuana



       8
         We have found no Fourth Amendment violation where a dog “instinctive[ly]”
jumped into an open hatchback and where “[t]here [was] no evidence . . . that the police
asked [the defendant] to open the hatchback so the dog could jump in” and no “evidence
the police handler encouraged the dog to jump in the car.” 

; see
also United States v. Vazquez, 

, 930 (10th Cir. 2009). However, in United
States v. Winningham, we distinguished Stone and suppressed contraband discovered in a
vehicle following a canine sniff of the interior where the officers lacked reasonable
suspicion that the car contained narcotics and opened the vehicle door through which the
dog jumped. 

, 1330-31 (10th Cir. 1998). “[T]he consensus among the
courts that have addressed this question appears to be that a canine sniff that migrates
from outside a car or other container to the interior does not constitute a violation of the
Fourth Amendment, provided that the canine makes entry into the suspect vehicle of its
own initiative and is neither encouraged into nor placed in the vehicle by a law
enforcement officer.” United States v. Hutchinson, 

, 506 (M.D. Pa.
2007).

                                            -12-
prior to leaning into Montes-Ramos’ vehicle. Under the plain view doctrine, “a

law enforcement officer [may] seize evidence of a crime, without violating the

Fourth Amendment, if (1) the officer was lawfully in a position from which the

object seized was in plain view, (2) the object’s incriminating character was

immediately apparent . . . and (3) the officer had a lawful right of access to the

object.” United States v. Angelos, 

, 748 (10th Cir. 2006) (quotations

omitted). The plain view doctrine is equally applicable to plain smells, such that

no search occurs if a police officer detects an odor of illegal drugs, alcohol,

chemicals or the like from a location in which he is entitled to be. See 

(“The plain smell doctrine . . . is simply a logical extension of the plain view

doctrine . . . .”) (quotations omitted); United States v. Merryman, 

,

784 (10th Cir. 1980) (“This Circuit has held that the smelling of marijuana by an

experienced observer furnishes probable cause for the search.”); see also 

(Stevens, J., dissenting) (“[A]romas that are generated in a

kitchen, or in a laboratory or opium den, enter the public domain if and when they

leave a building.”). But Rodriguez did not smell marijuana prior to leaning his

head into Montes-Ramos’ vehicle. Instead he was suspicious Montes-Ramos

might be trafficking drugs and leaned his head in “[f]or assurance.” (R. Vol. III

at 16.)

      2. Was It Reasonable?

      Our conclusion that the sniff was a search does not end the analysis

                                         -13-
because the Fourth Amendment commands only “that searches and seizures be

reasonable.” 9 United States v. Montoya de Hernandez, 

, 537 (1985).

The Supreme Court has explained: “What is reasonable depends upon all of the

circumstances surrounding the search or seizure and the nature of the search or

seizure itself. The permissibility of a particular law enforcement practice is

judged by balancing its intrusion on the individual’s Fourth Amendment interests

against its promotion of legitimate governmental interests.” 

citation omitted). If this were the Court’s only instruction, we would be inclined

to conclude the intrusion here was reasonable. It involved only a slight

encroachment into an area that is subject to Fourth Amendment protection only to

a limited degree. Montes-Ramos’ vehicle was lawfully stopped at the time of the

intrusion and he does not contend the intrusion prolonged the stop (the elapsed



       9
         The fact the intrusion was for an investigatory purpose is not relevant to our
analysis. “[T]he constitutional reasonableness of traffic stops [does not] depend[ ] on the
actual motivations of the individual officers involved . . . . Subjective intentions play no
role in ordinary, probable-cause Fourth Amendment analysis.” Whren v. United States,

, 813 (1996); see also Scott v. United States, 

, 138 (1978)
(“[T]he fact that the officer does not have the state of mind which is hypothecated by the
reasons which provide the legal justification for the officer’s action does not invalidate
the action taken as long as the circumstances, viewed objectively, justify that action.”).
Thus, in United States v. Villamonte-Marquez, the Supreme Court rejected the argument
that the customs officials’ ulterior motive for an otherwise valid warrantless boarding of a
vessel might strip the officials of their legal justification. 

, 584 n.3 (1983).
Similarly, in United States v. Robinson, the Court noted a traffic-violation arrest would
not be rendered invalid by the fact it was “a mere pretext for a narcotics search” and a
lawful post-arrest search of a person would not be rendered invalid by the fact it was not
motivated by officer safety concerns. 

, 221 n.1, 236 (1973).

                                            -14-
time from stop to sniff was less than one minute). Nor does he (or could he)

contest the importance and legitimacy of the government interest at stake here –

preventing the transportation of illegal narcotics.

      But the Supreme Court has also instructed that “warrantless searches are

presumptively unconstitutional.” 

. Searches conducted

without a warrant are permissible, of course, under certain well-delineated

exceptions to the warrant requirement. See Brigham City, Utah v. Stuart, 

, 403 (2006) (“[B]ecause the ultimate touchstone of the Fourth

Amendment is ‘reasonableness,’ the warrant requirement is subject to certain

exceptions.”). It is not the province of this Court to create a new (or expand an

existing) exception to the warrant requirement. Instead, our task is limited to

determining whether the government has met its burden of proving the search

falls within a recognized exception. See United States v. Maestas, 

,

1491 (10th Cir. 1993) (“[T]he government has the burden of proving that an

exception to the warrant requirement applies.”).

      The only apparent exception applicable here is the automobile exception,

pursuant to which “[t]he police may search an automobile and the containers

within it where they have probable cause to believe contraband or evidence is

contained.” Calif. v. Acevedo, 

, 580 (1991). It is tempting to find

probable cause for the sniff and affirm on the basis of our independent review of

the record. A legitimate argument could be made that Rodriguez had probable

                                         -15-
cause for his sniff search. 10 But, in spite of a clear opportunity, the government

has never made that argument.

      In his motion to suppress, Montes-Ramos contended the sniff was unlawful

because it was conducted without his consent and without a warrant. In response,

the government argued it had probable cause to search the vehicle based, in part,

upon the odor of marijuana. But the odor of marijuana cannot factor into the

probable cause analysis because Rodriguez did not smell marijuana until after he

leaned his head into the vehicle.

      At the suppression hearing, the judge was alert to this problem and

repeatedly invited the government to focus its attention on whether the sniff was a

permissible search. The government uniformly refused the court’s invitation to

address the critical issue and instead argued that Rodriguez had, prior to the sniff,

acquired enough information “to proceed further with his investigation.” (R. Vol.

III at 54.) The court stated it was concerned with “how that odor comes to



      10
         Rodriguez had knowledge of three facts and circumstances prior to his search of
Montes-Ramos’ vehicle which could have contributed to probable cause: (1)
Montes-Ramos was stopped forty miles from the U.S./Mexico border while traveling
north on a known drug trafficking route; (2) Rodriguez observed a five-inch circular
section of burlap protruding from underneath a blanket in the backseat; the blanket
appeared to be covering large objects which Rodriguez testified were consistent with
contraband but not produce; and (3) Rodriguez had approximately seventeen years of
experience as a law enforcement officer and had been involved in approximately twelve
drug-related arrests or investigations, two of which involved marijuana being transported
in burlap bags. These facts and circumstances could support a finding of probable cause
though, contrary to the view of the dissent, that resolution is not beyond any doubt.

                                          -16-
[Rodriguez].” (Id. at 55.) The government responded by citing cases holding a

defendant’s rights under the Fourth Amendment are not violated where an officer

smells an odor from a location in which he has a right to be. In response, defense

counsel argued:

      I think when you stick your nose in the car, that’s a search . . . . If
      Patrolman Rodriguez walked up to the car and out of the passenger
      window he smelled marijuana . . . we wouldn’t be having this
      conversation, because it would be an entirely different situation.
      And I think the cases that [the government] cites talk about situations
      in which the officer from a position that he was legally entitled to
      occupy, was able to discern some odor that he recognized as burned
      or raw marijuana.

(Id. at 59-60.) The government offered rebuttal argument relating to the stop but,

again, did not address the operative issue – whether Rodriguez had probable cause

for his intrusion into the vehicle to conduct his sniff search.

      Ultimately, in spite of its persistent and pertinent questioning, the court

abandoned its instincts and accepted the government’s argument, concluding the

sniff was permissible even in the absence of probable cause. It explained:

      The intrusion was minimal and was substantially outweighed by
      concerns for officer safety in light of the reasonable suspicion that
      Montes was engaged in smuggling a large quantity of marijuana.
      Deputy Rodriguez’s actions were objectively reasonable under the
      totality of the circumstances and within the range of activities that a
      police officer may permissibly engage in when he has reasonable
      suspicion to believe that a vehicle contains narcotics.

(R. Vol. I, Doc. 16 at 9.) It went on to hold that after Rodriguez smelled the

marijuana, “there was probable cause to arrest Montes and search the [vehicle].”


                                          -17-
(Id.)

        Even on appeal, the government does not squarely argue the sniff was

supported by probable cause. 11 It says even if the sniff was a search, it did not

violate the Fourth Amendment because it “‘stemmed from some probable cause

focusing suspicion on the individual affected by the search.’” (Appellee’s

Answer Br. at 19-20 (quoting 

(1986).) 12 It contends

that, prior to leaning into Montes-Ramos’ vehicle, Rodriguez directly observed a

traffic violation and “observed evidence that led him to believe that Montes’ car

contained a load of narcotics.” (

) The government states: “These

observations provided a sufficient connection between Montes and the subsequent

intrusion and support upholding the search.” (Id.) We are not sure what the

government means by “sufficient connection,” but if it is less than probable


        11
        The government also does not argue it had probable cause to search the car
independent of the sniff.
        12
           In Class, the Supreme Court held the officer’s search of the defendant’s vehicle
to obtain the VIN did not violate the Fourth Amendment “[i]n light of the danger to the
officers’ safety that would have been presented by returning respondent immediately to
his car . . . 

. The decision appears to rest, in part, upon the “important
interests served by the VIN.” See 

The Court explained: “[B]ecause of the
important role played by the VIN in the pervasive governmental regulation of the
automobile and the efforts by the Federal Government to ensure that the VIN is placed in
plain view, we hold that there was no reasonable expectation of privacy in the VIN.” 

That unique consideration is not present here. While reasonable suspicion is
sufficient to justify an investigatory stop, see 

, it is not
sufficient to justify a warrantless search. To the extent 

, can be read
to require only reasonable suspicion for a search of an automobile for narcotics, we
decline to follow it.

cause, it is not sufficient.

       If Rodriguez reasonably suspected Montes-Ramos was transporting illegal

narcotics, he could have detained Montes-Ramos and investigated further. He

could have asked if Montes-Ramos was transporting narcotics. See United States

v. Karam, 

, 1161 (10th Cir. 2007). He could have asked for

consent to search the vehicle. See United States v. Sanchez, 

, 719

(10th Cir. 1996). He could have stood at the car door, waiting for the smell of

marijuana to waft out the window. See 

. He could have

called for a drug dog to sniff the exterior of the vehicle. See United States v.

Morales-Zamora, 

, 203 (10th Cir. 1990) (holding a canine sniff on a

legitimately detained automobile is not a “search” within the meaning of the

Fourth Amendment). And if his suspicion about drug trafficking caused him to

fear for his safety, he could have removed Montes-Ramos from his vehicle, 13 see

Pennsylvania v. Mimms, 

, 111 n.6 (1977), or looked (perhaps even

slightly intruded) into the vehicle to determine whether there were weapons

within Montes-Ramos’ reach, see Michigan v. Long, 

, 1050




       13
          The government contends because Rodriguez could have removed Montes-
Ramos from his vehicle without violating the Fourth Amendment, surely he could have
taken the less intrusive action of leaning into Montes-Ramos’ window to sniff for drugs.
We disagree. The purpose of removing a driver from a vehicle is to ensure officer safety.
See 

. That purpose is not evident here therefore it does not matter
that the sniff was a less intrusive alternative.

                                          -19-
(1983). 14 He could not, however, engage in a warrantless sniff search for drugs –

even a minimally intrusive one – unless he had probable cause to believe the

vehicle contained contraband or evidence of a crime.

       Where, as here, a defendant makes a clear argument in support of a motion

to suppress and the government fails to respond to that argument, even when

expressly (and repeatedly) invited by the court to do so, the argument is waived.

See United States v. Teague, 

, 1314 (10th Cir. 2006) (“[A] party

that has forfeited a right by failing to make a proper objection may obtain relief

for plain error; but a party that has waived a right is not entitled to appellate

relief.”); see also Singleton v. Wulff, 

, 120 (1976) (“It is the general

rule, of course, that a federal appellate court does not consider an issue not passed

upon below.”); Rosewood Servs., Inc., v. Sunflower Diversified Servs., Inc., 

, 1167 (10th Cir. 2005) (holding argument not asserted before district

court is waived on appeal). This is especially true where the government does not

even argue the issue with clarity on appeal. 15 See Bronson v. Swensen, 

         The district court noted in passing that “[c]oncerns for officer safety may justify
a limited search of a vehicle,” (R. Vol. I, Doc. 16 at 8), but there was no evidence or
argument about officer safety. To his credit Rodriguez did not, post hoc, claim his search
was motivated, even partially, by a concern for his safety.
       15
         Even if we could, charitably, construe the government’s appellate brief as
arguing the sniff was supported by probable cause, we see no “compelling reasons” to
depart from our general waiver jurisprudence. See Crow v. Shalala, 

, 324
(10th Cir. 1994) (“Absent compelling reasons, we do not consider arguments that were
not presented to the district court.”). Nevertheless, “we are free to affirm a district court
decision on any grounds for which there is a record sufficient to permit conclusions of

that are not raised, or are inadequately presented, in an appellant’s opening

brief.”); Dubbs v. Head Start, Inc., 

, 1202 n.2 (10th Cir. 2003)

(where a party does not brief an issue on appeal, the argument is waived).

      Accordingly, we REVERSE the district court’s partial denial of Montes-

Ramos’ motion to suppress and REMAND for suppression of the fruits of the

sniff search and such other necessary proceedings consistent with this Order and

Judgment.

from our waiver bar, even if we could conceivably affirm for reasons not argued to, or
decided by, the district court.

07-2027, United States v. Montes-Ramos

BRISCOE, J., dissenting:

      Remarkably, in the face of an uncontroverted factual record that establishes

Officer Rodriguez had probable cause to search Montes-Ramos’ vehicle prior to

“the sniff,” the majority chooses to order suppression of the evidence found in the

vehicle, and presumably thereby undo Montes-Ramos’ conviction, because the

government has purportedly “waived” any argument that probable cause existed.

I strongly disagree with both the majority’s analysis and its outcome.

                                          I

      Recently, in United States v. Cruz-Rodriguez, 

(10th Cir.

2009), we distinguished between “waiver” and “forfeiture” in the context of a

criminal case. “‘Waiver,” we noted, “is the intentional relinquishment or

abandonment” of an issue, whereas “‘forfeiture is the failure to make the timely

assertion’” of an issue. 

(quoting United States v. Olano, 

, 733 (1993) (internal quotation marks omitted)). “In other words,” we held,

“waiver is accomplished by intent, but forfeiture comes about through neglect.”

marks omitted). In turn, we noted that these two concepts

have a significant impact on “the availability of appellate review . . . .” 

have been merely forfeited remain eligible for appellate review. 

have been waived, however, are not subject to appellate review. 

principles here, the government’s failure to sufficiently

argue the issue of probable cause at the time of the suppression hearing could be
described as neglectful. But, reviewing the entire record, it cannot seriously be

asserted that the government intentionally abandoned that issue. As a general

matter, the government vigorously opposed Montes-Ramos’ motion to suppress

and argued that the evidence seized from his vehicle should be deemed

admissible. After persuading the district court to uphold Officer Rodriguez’s

sniff search on safety grounds, there was no need for the government to argue

probable cause as an alternative basis for the search. In this appellate forum, with

the search again at issue, the government has properly seen fit to offer alternative

rationales for the search, including probable cause. In particular, the

government’s appellate brief expressly asserts that “Officer Rodriguez’ sniff

‘stemmed from some probable cause focusing suspicion on the individual affected

by the search.’” Aplee. Br. at 19-20 (quoting New York v. Class, 

,

117-18 (1986)). In support of that argument, the government notes that “before

Officer Rodriguez intruded into the car’s airspace, he had . . . observed evidence

that led him to believe that Montes’ car contained a load of narcotics,” and that

“[t]hese observations provided a sufficient connection between Montes and the

subsequent intrusion and support upholding the search.” 

Consequently,

we are not, as the majority erroneously asserts, dealing with a waiver. Rather, we

are, at most, dealing with a potential forfeiture of the probable cause argument

due to the government’s failure to assert it below.

      “Although a litigant’s failure to raise an argument before the district court

                                         -2-
generally results in forfeiture on appeal, forfeiture is not jurisdictional.” United

States v. Jarvis, 

, 1201 (10th Cir. 2007). “Whether to address the

argument despite the litigant’s failure to raise it below is subject to this court’s

discretion based on the circumstances of the individual case.” 

the Supreme Court has indicated appellate courts might be justified in resolving

an issue for the first time on appeal ‘where the proper resolution is beyond any

doubt or where injustice might otherwise result.’” 

(quoting

Singleton v. Wulff, 

, 121 (1976)). Consistent with Singleton’s

direction, this court has exercised its discretion to hear issues raised for the first

time on appeal where “no additional findings of fact or presentation of evidence

were required for the issue’s disposition and both parties had the opportunity to

address the issue in their appellate briefing.” 

      A review of the record in this case establishes that it fits cleanly within the

narrow exception identified in Jarvis. To begin with, the suppression proceedings

below, which included Officer Rodriguez’s descriptive testimony regarding the

details of the stop, “resulted in a record of amply sufficient detail and depth from

which the [probable cause] determination may be made.” United States v.

McSwain, 

, 562 (10th Cir. 1994) (internal quotation marks omitted).

Consequently, “no additional findings of fact or presentation of evidence [a]re




                                           -3-
required for . . . disposition” of the probable cause issue. 1 

; see Crescent City Live-Stock Landing & Slaughter-House Co. v. Butchers’

Union Slaughter-House & Live-Stock Landing Co., 

, 149 (1887)

(“[W]hen there is no dispute of fact, the question of probable cause is a question

of law . . . .”). Further, as noted, the government has argued the issue of probable

cause in its appellate brief, and Montes-Ramos has responded directly to that

argument. Aplt. Reply Br. at 5-7 (arguing that Class, the Supreme Court case

cited by the government, is distinguishable from the instant case). Thus, “both

parties [have] had the opportunity to address the issue [of probable cause] in their

appellate briefing.” 

.

       The public’s long-recognized interest in the “conviction of guilty

criminals,” United States v. Murphy, 

, 211 (1842), also, I believe,

weighs in favor of reaching the issue of probable cause. As the majority opinion

makes clear, Officer Rodriguez’s sniff search of Montes-Ramos’ vehicle can only

be justified, and in turn the evidence seized from that vehicle can only be deemed

admissible, if there was probable cause for the search. In other words, absent our

consideration of the probable cause issue, the evidence will be suppressed and, in

turn, Montes-Ramos’ otherwise valid conviction will be set aside. Thus, I believe

          This is also consistent with our well established rule that we may “affirm a
district court on a previously unexplored ground,” so long as there is a record sufficient to
permit any necessary conclusions of law. United States v. Pursley,

      Probable cause to search an automobile exists “where the known facts and

circumstances are sufficient to warrant a man of reasonable prudence in the belief

that contraband or evidence of a crime will be found.” Ornelas v. United States,

, 696 (1996) (citations omitted); see also United States v.

Concepcion-Ledesma, 

, 1316 (10th Cir. 2006) (examining whether

“the facts observed by the law enforcement officers indicate a fair probability that

the vehicle contains contraband or evidence”). We view the facts “from the

standpoint of an objectively reasonable police officer.” 

.

“[W]e must look at the totality of the circumstances of each case to see whether

the detaining officer ha[d] a particularized and objective basis for suspecting legal

wrongdoing.” 

(quoting United States v.

Arvizu, 

, 273 (2002)) (internal quotation marks omitted).

      According to the record on appeal, Officer Rodriguez observed a blanket

covering large bundles in the back seat, with burlap visible where a bundle was

not covered by the blanket. Rodriguez testified that one method of shipping

marijuana is to pack it into bricks wrapped with burlap cloth. Based on

Rodriguez’ experience with the transportation of controlled substances, which

included two drug busts that involved the use of burlap to transport contraband,

                                         -5-
Rodriguez determined that the visual appearance of the bundles was consistent

with the packaging of contraband and not with the packaging of legal agricultural

products. 

47-48. 2

      Additional facts known to Rodriguez, in combination with his observation

of packaging consistent with contraband, in my view established a fair probability

that the vehicle contained contraband. See 

(concluding

that officer’s recognition of 2 x 2 inch bags in the front seat of a vehicle “as being

the ‘size and type used to distribute drugs,’” combined with other facts known to

the officer at the time, established probable cause to search the vehicle). Montes-

Ramos was driving along Highway 80, “a known drug-smuggling route.” Dist.

Ct. Mem. Op. at 1. Montes-Ramos’ temporary registration permit had been

placed on the vehicle in violation of state law and in such a manner as to be

virtually unreadable while the vehicle was in motion. The burlap bundles in the

         Although Rodriguez did not explain more fully why he thought the packaging
conformed to the smuggling of marijuana and not to the shipment of legal products, it is
well-established that “a police officer may draw inferences based on his own experience
in deciding whether probable cause exists.” 

(citing United
States v. Ortiz, 

, 897 (1975)). As a reviewing court, we must “defer to the
ability of a trained law enforcement officer to distinguish between innocent and
suspicious actions.” 

(citations and internal quotation marks
omitted). As the district court generally accepted Rodriguez’ testimony and specifically
accepted his observation that the packaging indicated contraband, see generally Dist. Ct.
Mem. Op. at 3, 7, we must give “due weight” to the district court’s findings and accept
Rodriguez’ testimony, even though it was rather conclusory, 

(“An appeals court should give due weight to a trial court’s finding that the officer was
credible and the inference was reasonable.”).

back seat of Montes-Ramos’ car were covered almost entirely with a blanket.

That one would attempt to conceal the bundles from view is more consistent with

an attempt to conceal contraband than with the transport of lawful agricultural

products. Finally, Montes-Ramos was northbound and traveling away from the

Mexican border, which is consistent with Rodriguez’ suspicion that Montes-

Ramos was smuggling drugs into the country. Cf. United States v. Valenzuela,

, 901 (10th Cir. 2004) (rejecting the government’s contention that

mere proximity to the border, by itself, would constitute probable cause, without

ruling out proximity to the border as a factor in the probable cause analysis).

      For the foregoing reasons, I respectfully DISSENT and would affirm both

the district court’s denial of Montes-Ramos’ motion to suppress and the judgment

of conviction.
