April 6, 1992, a confidential informant received a tip that cocaine
could be purchased at "Los Companeros," an auto body repair shop
operated by two brothers, Eduardo Gonzalez Rodriguez ("Eduardo") and
Luis Gonzalez ("Luis"). The informant went to the shop, accompanied
by one Harry Burgos, and there encountered Jose Algarin Rosa ("Al-
garin"), apparently an employee. The informant asked Algarin about
the possibility of purchasing a half kilogram of cocaine. Algarin
told the informant that in order to purchase this amount, the infor-
mant would need to talk to Luis.
As the informant was leaving the shop, Luis arrived, accom-
panied by Eduardo. Algarin made introductions. With Algarin and
3
Eduardo present, the informant again asked to purchase a half kilogram
of cocaine. Luis consulted with Eduardo and offered to sell one-
eighth of a kilogram of cocaine for $3000; the informant declined the
offer. Luis then indicated that a large shipment was due from Vieq-
ues, Puerto Rico, and that when the shipment arrived he could sell the
informant a full kilogram for $16,000. The informant tentatively
assented.
On April 13, 1992, the informant met again with Luis, who
stated that he had received the shipment from Vieques and was ready to
complete the kilogram deal. The informant gave Luis his beeper number
and left, ostensibly to get the purchase money. Around 3:00 p.m., the
informant returned to the repair shop, accompanied by Ruben Diaz Padro
("Diaz"), a federal undercover agent. Luis and Algarin were both
present. Before the transaction could be consummated, however,
Eduardo entered and warned Luis that there were police nearby. Luis
thereupon arranged to meet the informant on a nearby road. Accompa-
nied by Diaz, the informant drove to the site of the proposed rendez-
vous, and parked as instructed. A few minutes later, the informant
and Diaz observed Eduardo drive by in a wine-colored BMW automobile.
After several passes, Eduardo pulled over and parked in front of the
informant's automobile. Luis pulled in behind. Using hand signals,
Luis attempted to lead the informant to a third site, with Eduardo
following in his own car. Because the informant was uncomfortable
with this change in plans, he declined to follow, and drove away.
4
Later that afternoon, Luis called the informant's beeper
number and agreed to complete their kilogram transaction at the repair
shop. Eduardo greeted the informant on arrival and instructed him not
to park in front of the shop. As the informant and Diaz made their
way into the office, Algarin reassured the informant of Luis's hones-
ty: "Do not be afraid, they do not deal with tricks." Eduardo, who
was leaving the office as the informant met with Luis, advised Luis on
how to remove the cocaine from its bag: "That is not the way that it
is done. Don't take it out like that." Shortly thereafter, at the
informant's signal, federal agents raided the repair shop. Luis was
arrested in the office. Algarin attempted to run away, but was
arrested after a scuffle with DEA agents at the shop gate. Eduardo
was arrested on the street nearby. All were indicted for aiding and
abetting the distribution of cocaine.
The defendants were joined for trial, over Eduardo's objec-
tion. On May 4, 1992, the defense filed an omnibus discovery motion,
seeking, inter alia, "all information which may be used for impeach-
_____ ____
ment of government witnesses." The government disclosed that an
administrative fine had been imposed on the informant for marijuana
possession in New York. The government disclaimed knowledge of any
other impeachment material relating to the informant.
Ultimately, Luis entered a guilty plea; Eduardo and Algarin
went to trial. In an effort to discredit the informant's testimony,
the defense called Esteban Garcia Rosario ("Garcia"), a former ac-
quaintance of the informant, who testified that the informant had used
5
and dealt drugs in the past. To rebut Garcia's testimony, the prose-
cution recalled the informant. The informant admitted knowing Garcia
and, later, on cross-examination, admitted that he had once purchased
drugs from Garcia "for a friend." Both defendants asserted that the
government should have disclosed this information prior to trial,
relying on Brady v. Maryland, 373 U.S. 83 (1963), and moved for
_____ ________
judgments of acquittal under Fed. R. Crim. P. 29. The court denied
their motion.
In the course of his redirect examination by the government,
the informant was asked whether he "had any personal knowledge if
[Garcia] was acquainted with Eduardo Gonzalez or Luis Gonzalez and
Algarin." The informant responded in Spanish: "as to Algarin I don't
know, but I do know that he [Garcia] bought one eighth [kilogram] of
cocaine from . . . Eduardo Gonzalez." Before the answer could be
translated into English, both defendants moved for mistrial, invoking
the rule on "other acts" evidence. See Fed. R. Evid. 404(b). Reserv-
___
ing its ruling on the mistrial motion, the district court gave the
government an opportunity to show that the informant's statement was
based on personal knowledge of Garcia's prior drug sources under
Evidence Rule 602. Eventually, the informant was permitted to testi-
fy: "I used to visit him [Garcia] at his house and I know that he was
buying from Luis and Eduardo." A few hours later, as part of its jury
charge, the court delivered a curative instruction proposed by defen-
dants:
6
"I instruct you, ladies and gentlemen of the jury,
that the defendants are on trial solely and exclu-
sively on the charge set forth in the indictment
and nothing else. So therefore I instruct you
that you should disregard, that is, get out of
your mind completely, [the informant's] testimony
concerning [Garcia's] prior dealings with the
defendant. It has nothing to do with this case
and it is irrelevant and you should not consider
it at all for any purpose whatsoever in your de-
liberation . . . ."
Algarin and Eduardo were both convicted.

DISCUSSION
DISCUSSION
__________
Appellants' first contention is that the district court
erred in denying their motion for mistrial based on the informant's
testimony that Garcia had purchased "one eighth [kilogram] of cocaine
from . . . Eduardo Gonzalez." Assuming, for present purposes, that
the informant's statement was inadmissible against appellants,1 we
review for "abuse of discretion" the district court's election to give
a cautionary instruction, rather than declare a mistrial, to counter-
act any prejudicial effect which may have resulted from the challenged
testimony. See, e.g., United States v. Bello-Perez, 977 F.2d 664, 672
___ ____ _____________ ___________
(1st Cir. 1992); United States v. Sclamo, 578 F.2d 888, 890-91 (1st
_____________ ______
Cir. 1978).
____________________
1Rule 404(b) provides that "[e]vidence of other crimes, wrongs,
or acts is not admissible to prove the character of a person in order
to show action in conformity therewith. It may, however, be admissible
for other purposes, such as proof of motive, opportunity, intent,
preparation, plan, knowledge, identity, or absence of mistake or
accident." Fed. R. Evid. 404(b).

There was no abuse of discretion. Even assuming, for
purposes of discussion, that some improper prejudice may have resulted
from the informant's testimony, the degree of any such prejudice,
______
assessed from the vantage point of a "cold appellate record," see
___
Freeman v. Package Mach. Co., 865 F.2d 1331, 1340 (1st Cir. 1988), was
_______ _________________
plainly insufficient to warrant second-guessing the trial court's
judgment that its jury instruction was adequate cure for any possible
unfair prejudice. Moreover, although appellants now fault the dis-
trict court's failure to give a contemporaneous instruction, there is
no indication in the appellate record that one was requested. See
___
United States v. Valencia-Lucena, 925 F.2d 506, 513-14 (1st Cir. 1991)
_____________ _______________
(review "limited to plain error" where defendant eschewed request for
limiting instruction upon trial court's denial of mistrial motion).
Rather, the court permitted the defense to draft a curative instruc-
tion which was included in the jury charge delivered a few hours
later. "We normally presume that a jury will follow an instruction to
disregard inadmissible evidence inadvertently presented to it, unless
there is an 'overwhelming probability' that the jury will be unable to
follow the court's instructions." Greer v. Miller, 483 U.S. 756, 766
_____ ______
n.8 (1987) (quoting Richardson v. Marsh, 481 U.S. 200, 208 (1987)).
__________ _____
Whether or not the brief interval between the subject testimony and
the curative instruction was the product of a tactical choice on the
part of the defense, it did not amount to "plain error."
Appellants contend that the government's failure to disclose
the informant's prior dealings with Garcia, in response to a discovery
8
request from the defense for "all information which may be used for
impeachment of government witnesses," constituted a Brady violation.
_____
Once again we assume, for purposes of discussion, that Garcia's
testimony relating to the informant's prior cocaine dealings was
potentially exculpatory, and we accept the government's concession
that it was material, in the sense that its disclosure would "create a
reasonable probability . . . that the result of the proceeding would
be different." United States v. Bagley, 473 U.S. 667, 682 (opinion of
_____________ ______
Blackmun, J.) (1985); United States v. Osorio, 929 F.2d 753, 758 (1st
_____________ ______
Cir. 1990). In order to warrant reversal, however, a delayed disclo-
sure of material evidence must be shown to have "prevented [the
defense] from using the disclosed material effectively in preparing
and presenting the defendant's case." United States v. Ingraldi, 793
_____________ ________
F.2d 408, 411-12 (1st Cir. 1986); United States v. Devin, 918 F.2d
______________ _____
280, 289-90 (1st Cir. 1990); United States v. Osorio, 929 F.2d 753,
_____________ ______
757 (1st Cir. 1991). In the present case, the defense was well aware
of the informant's prior cocaine dealings with Garcia prior to trial.
Indeed, Garcia was called as a witness by the defense, for the very
__ ___ _______
purpose of testifying to these matters.2 Accordingly, there was no
showing that prejudice resulted from the delayed disclosure. See
___
Valencia-Lucena, 925 F.2d at 514 ("[T]he fact that the government

would do so and here I am."

failed to disclose to the defense before trial that [its informant]
was a drug user in no way robbed the defendant of a fair trial because
the issue was fully revealed at trial and extensively explored during
cross-examination").
Finally, appellants challenge the sufficiency of the evi-
dence, claiming that they were "merely present" at the scene of Luis's
drug dealing activities, and reminding us that evidence of "mere
presence" is insufficient to support their convictions. See Ortiz,
___ _____
966 F.2d at 707 (1st Cir. 1992); United States v. Francomano, 554 F.2d
_____________ __________
483, 486 (1st Cir. 1977). We evaluate their claim under well-estab-
lished standards. Although "neither mere association with the princi-
pal nor mere presence at the scene of the crime . . . is sufficient to
establish aiding and abetting . . . .," United States v. Alvarez, 987

("culpability of a defendant's presence hinges upon whether the
circumstances fairly imply participatory involvement"). Here, in
addition to his presence at the repair shop, the government offered
evidence that Eduardo (1) consulted with Luis on April 6, as to the
10
price and quantity of the cocaine offered to the informant; (2)
watched for, and warned Luis about, police presence in the area of the
repair shop on April 13; (3) accompanied Luis in a separate car to the
site of the aborted first transaction; (4) told the agents where to
park their car when they arrived to consummate the transaction; and
(5) evinced familiarity with (and some measure of responsibility for)
the cocaine transaction, just prior to the DEA raid, by telling Luis
how to handle the cocaine. In addition to Algarin's "mere presence"
at the repair shop, the government presented evidence that Algarin (1)
introduced the informant to Luis, after learning that the informant
sought to purchase a large quantity of cocaine; (2) stood next to Luis
during negotiations with the informant on April 6; (3) evinced famil-
iarity with Luis's business practices, and sought to offer reassurance
to the informant and undercover agent ("don't be afraid, they don't do
tricks here"), when the informant arrived to consummate the drug
deal; and, finally, (4) ran from the shop, scuffling with a DEA agent
at the gate, when the raid began. Cf. United States v. Hernandez, No.
