                        November 17, 2006
            TORRUELLA, Circuit Judge. Lionel Cormier ("Cormier") was

convicted of possession with intent to distribute a controlled

substance    in    violation   of    18    U.S.C.    §   841(a),    conspiracy     to

distribute a controlled substance in violation of 18 U.S.C. § 846,

possession    of    a   firearm     during      a   drug-trafficking       crime   in

violation of 18 U.S.C. § 924(c)(1)(a)(ii), and being a felon in

possession of a firearm in violation of 18 U.S.C. §§ 922(g) and

924(e).     Cormier      appeals      his       conviction.        After    careful

consideration, we affirm.

                               I.    Background

            In early 2003, Cormier met with his friend David Finch

("Finch") and began to discuss plans to rob drug dealers and

purchase guns. Cormier also met with Stephen Depka ("Depka"), with

whom he discussed a proposal to transport marijuana from Maine to

Massachusetts.      Depka refused the proposal.            Cormier nevertheless

began investigating potential robbery targets.

                            The Darragh Robbery

            Finch's then-girlfriend, Tracy Paquette ("Paquette"),

suggested to Cormier that he rob Michael Darragh ("Darragh"), whom

she believed to be a drug dealer and whose house was located in

Maine.    Paquette called a friend, Winston Hanson ("Hanson"), to

verify that Darragh had drugs in his house.               Hanson confirmed that

Darragh did, in fact, possess drugs.                 Cormier later decided to

include Hanson in the robbery plans.


                                          -2-
           Around midnight on March 23, 2003, Cormier, Finch, and

Hanson robbed Darragh's house.   Finch and Cormier put on ski masks

and gloves and broke into Darragh's house; Hanson stayed in the car

as a lookout.    Cormier and Finch found Darragh inside his house.

When confronted with a gun, Darragh told Cormier and Finch that his

drugs were in his jacket pocket.   Finch removed 20 to 30 Oxycontin

pills, "some" Percocet pills, walkie-talkies and knives from the

jacket.    Finch also took $800-$900 in cash.   After the robbery,

Cormier, Finch, and Hanson returned to Hanson's home.    There was

general agreement among witnesses at trial that Cormier took all of

the money.    In addition, Finch testified at trial that Cormier

traded pills to Hanson for marijuana, whereas Hanson testified that

Cormier paid for the marijuana in cash. After the Darragh robbery,

Cormier had an acquaintance purchase a Ruger .454 Magnum gun for

him.

                          The Kane Robbery

           The second robbery took place on June 11, 2003, also in

Maine, at the house of Steve Kane, a drug dealer known to Cormier.

Cormier and Finch obtained the help of Michael Gleason ("Gleason")

for the robbery; Hanson was no longer involved.     Paquette drove

Gleason and Cormier to Kane's house, armed with the Ruger .454

Magnum, ski masks, gloves, and zip ties, as well as walkie-talkies,

which were to be used to contact Finch at the conclusion of the

robbery.     Cormier and Gleason entered Kane's house, but found


                                 -3-
nobody at home.   Gleason searched the house and discovered a rifle

and a handgun, which he took.   Cormier and Gleason then waited for

Kane to come home.    Kane arrived at his house carrying a duffel

bag.   Cormier and Gleason confronted Kane, and told him that they

wanted his money and marijuana.       Gleason took five pounds of

marijuana from Kane's duffel bag and $500 from Kane's truck.

Cormier and Gleason then fled. Finch picked up Cormier and Gleason

in a cemetery near Kane's home.    Upon returning to Finch's home,

the proceeds of the robbery were divided.       Cormier allocated to

Finch and Paquette1 one pound of the stolen marijuana to share and

divided the remainder between himself and Gleason. Cormier, Finch,

and Gleason then proceeded to smoke some of the marijuana.

                         The Dyer Robbery

           The third robbery took place a few hours after the Kane

robbery.   Cormier had heard that Tom Dyer ("Dyer") had previously

been arrested for possession of large amounts of marijuana and

believed that Dyer would likely have drugs at his house.       Finch

drove Cormier and Gleason in Paquette's car to Dyer's home.     Upon

arriving, Cormier, Finch, and Gleason congregated in front of

Dyer's house discussing their plans.        Dyer awoke and went to

investigate.   Cormier broke the front window with his gun, reached

in to unlock the door, and entered the house.    Dyer yelled that he

   There is some conflict in the testimony as to whether Paquette
received a share of the marijuana directly from Cormier.

                                -4-
was going to call the police.     The police arrived, and Cormier,

Gleason and Finch scattered.

          Gleason was apprehended shortly after police arrived.

Finch spent the night in the woods by Dyer's house, but was

apprehended the next morning.   Paquette's car was discovered near

Dyer's home; after Paquette consented to a search of it, wallets

belonging to Gleason and Finch, as well as gloves and walkie-

talkies were found therein.    Cormier escaped by stealing a canoe,

paddling across a lake, and walking to a donut shop, where he

called his girlfriend to pick him up.   Cormier called Paquette the

morning following the attempted robbery of Dyer and instructed her

to give Finch, Gleason, and himself their respective shares of

marijuana as per their discussion the previous night, and that

Gleason's share should go to Jeff Simpson ("Simpson") to pay for

Gleason's bail.   Cormier also instructed Paquette that a man would

come to collect his share of the marijuana and guns, which were

left in a bag.     Five days after the robbery, Vincent Andrews

("Andrews"), an acquaintance of Cormier, arrived at Paquette's

house to collect Cormier's bag.    Andrews testified at trial that

Cormier had paid him $50 to retrieve the bag, but that he never

looked inside it. A year after the attempted Dyer robbery, Cormier

was arrested and charged with possession of a controlled substance

with intent to distribute, conspiracy to distribute a controlled




                                 -5-
substance, possession of a firearm during a drug trafficking

offense, and being a felon in possession of a firearm.

              Motion to Exclude the ATF Agent's Testimony

              Prior to trial, the Government notified Cormier that it

would offer Brent McSweyn ("McSweyn"), an Alcohol Tobacco and

Firearms agent, to testify as an expert regarding whether the guns

used   in   the     crimes   had   passed    through    interstate    commerce.2

Cormier made a motion in limine to exclude McSweyn's testimony. In

response, the Government explained that McSweyn had testified

before   as    an   "interstate     nexus    expert,"    and   had   toured   gun

manufacturing facilities, spoken with manufacturers, and consulted

reference materials. McSweyn submitted a written "Interstate Nexus

Statement" in response to Cormier's motion, in which McSweyn stated

that the firearms charged in the indictment were manufactured

outside of Maine (and thus had traveled in interstate commerce).

The statement indicated that McSweyn had inspected the Ruger .454

Magnum and compared it with manufacturing records, two reference

texts, and his observations in manufacturing plants. The statement

further indicated that McSweyn had compared a written description

of the rifle, including model, caliber, and serial number, with

manufacturing reports and reference texts.              Lastly, the statement



2
   21 U.S.C. § 922(g) criminalizes possession, by a felon, of a
firearm "which has been shipped or transported in interstate
commerce." Thus, whether the gun has crossed state lines is an
element of the offense.

                                       -6-
indicated that McSweyn had compared a written description of the

handgun with manufacturing reports, reference texts, observations

in manufacturing plants, and a firearms trace report.     The court

tentatively overruled Cormier's objections to McSweyn's testimony,

but allowed Cormier to voir dire him.     During voir dire, McSweyn

testified that the gun manufacturer records he relied upon were not

available to the public.   After Cormier concluded the voir dire,

the court reaffirmed its denial of Cormier's motion, noting that

"the public could 99 percent of the time receive information as to

manufacturer and location from the public record, [but] that of

course, does not take away from the ability to offer expert

testimony on a particular issue."

                      The Opening Statement

          The trial began in March 2005.        During her opening

statement, the prosecutor said:

          You will hear from Michael Gleason and Mike
          Darragh and Jody Darragh, and from the start
          they admitted they were drug dealers and told
          the truth and you will also hear from Tracy
          Paquette and from David Finch and it will be
          up to you to determine whether they are
          telling the truth.

          Cormier objected; the court sustained the objection,

noting, "That is for closing."    The prosecutor continued, stating:

          And you will hear from Travis Sawyer who
          bought the 454, and victims of the Bucksport
          robbery. He had to admit that he was dealing
          marijuana before he could come in and testify
          in court . . . . And you will hear from Meg
          Donelan, Mr. Cormier's girlfriend, who drove

                                  -7-
            him home and covered for him when the police
            came for interview.     These people are not
            people who want to help the police, they are
            not people who volunteer information and not
            people who by any means who would choose to be
            on the stand testifying.

            Cormier objected again, and the court sustained the

objection, cautioning, "It's not argument.       This is opening in

terms of what you expect to show for evidence."       The prosecutor

continued, stating:

            The other point I wanted to make, and
            understanding that the key witnesses might
            have credibility problems, is that the
            government has taken every step it could to
            corroborate as many of the details these
            witnesses will testify to as possible. . . .
            [describing some of the corroboration] . . .
            While the first line of witnesses may be
            impeachable, this second line of witnesses and
            evidence is not.

            Cormier again objected, and the court sustained the

objection, warning the prosecutor not to "indicate argument as to

what is impeachable or not.    Present the evidence you're going to

present."   Cormier then moved for a mistrial.   The court denied the

motion, stating:

            I think there were instances where the
            prosecutor   came   close  to   vouching   for
            witnesses or indicating the witnesses were
            telling the truth.     I don't know that you
            stepped over that line. I was uncomfortable
            as to the degree of closeness. I will give
            the jury a cautionary instruction. I think in
            terms of this case, I don't think it has
            poisoned the well. This is a long trial, I'm
            not sure that the jury will remember anything
            about openings by the time they get this case.
            I will give them cautionary instructions and

                                 -8-
           we'll move on. I don't think they have been
           poisoned by what they've heard.

           The court then cautioned the jury:

           I told you earlier statements by counsel are
           not evidence and therefore you have not heard
           any evidence in this case. What they told you
           is not evidence. Number two. To the degree
           counsel has indicated to you that they believe
           a particular witness is telling the truth or
           not   telling   the  truth,   disregard   that
           entirely, it is not for counsel to indicate,
           it's up to you to determine.     In addition,
           counsel is not permitted to indicate to you
           that they believe someone is telling the truth
           or they are likely telling the truth. There
           again, it is for you to understand and
           determine and not for anyone else to tell you
           or to determine.      So you are to ignore
           entirely such statements.

                               The Trial

           The trial proceeded, and the Government's witnesses,

including Finch, Paquette, and Gleason testified to the foregoing

facts.   In particular, ATF Agent McSweyn testified in accordance

with the "Interstate Nexus Report" he had offered in response to

Cormier's motion.     Agent McSweyn testified that the Ruger .454

Magnum   was   manufactured   in   New   Hampshire   and   shipped   to   a

distributor in Massachusetts, and then was shipped to a retailer in

Maine where it was purchased. Agent McSweyn further testified that

the handgun was manufactured in Arizona or New Hampshire and that

the rifle was manufactured in Connecticut.      Cormier objected every

time Agent McSweyn testified about the origin of a firearm.




                                   -9-
          Cormier chose not to testify in his own defense.      On

cross-examination, Finch admitted that he had lied about the

robberies in his testimony before a grand jury.   Finch, Paquette,

and Gleason all admitted that they cooperated with the police in

exchange for more lenient sentences.      In addition, Finch and

Gleason admitted to having prior criminal records.

                      The Closing Argument

          During her closing argument, the prosecutor stated:

          So    when   you    make   your    credibility
          determinations, ladies and gentlemen, bear in
          mind that it's not just what the witnesses
          said that you can consider to determine
          whether they are telling the truth.     All of
          that evidence that I've just gone over in some
          detail bolsters what they said here on the
          stand.
                               . . .
          The ultimate decision on credibility is yours
          but the government suggests that it took a lot
          of honor and courage for those witnesses to
          testify, to stare [Cormier] in the face and
          tell their stories and that they are worthy of
          their belief.
                              . . .
          I said during my opening that one of the
          things you will need to consider in this case
          is Mr. Cormier's own words and actions,
          because what else better is there to tell what
          a person is thinking than by watching what
          they are saying what they are doing. I would
          like you to review one last point on the issue
          of Mr. Cormier's own credibility. . . . Ladies
          and gentlemen, it is said you can tell a lot
          about a person by the company he keeps. This
          week you have seen on the witness stand the
          company that Lionel Cormier keeps. They were
          robbers. They were drug dealers. They were
          felons. They were drug addicts. The government
          sure did not choose the witnesses in this
          case, in fact in a very real sense Mr. Cormier

                              -10-
          did.   Because until Mr. Cormier was charged
          with this crime, these people were his trusted
          associates, his long time friends, even the
          woman with whom he shared his home.
                              . . .
          [The witnesses] may not be model citizens, and
          they may not be people you want your children
          to marry, but their testimony is worthy of
          your belief, especially when considered in the
          light of all the other evidence you will have
          before you in your deliberations.

          Cormier moved for a mistrial, arguing, "Mr. Cormier's

credibility is not an issue in this trial."   The court denied the

motion, replying:

          [G]overnment counsel has come perilously close
          on closing to comment[ing] on the defendant's
          non[]-testimony, including the statements with
          regard to the [what] only evidence in the case
          is . . . . [and the] comments on his
          credibility. . . . The government [also] came
          perilously close by vouching for certain
          witness' testimony. . . . I don't think that
          the closing stepped over the line and I'm not
          going to declare a mistrial.

          The court then offered to give additional instructions to

the jury if the defense so requested, but Cormier declined to do

so.

                      The Jury Instructions

          At the conclusion of the trial, Cormier requested a jury

instruction based on his reading of the holding of the Second

Circuit in United States v. Swiderski, 548 F.2d 445 (2d Cir. 1977).

Cormier's proposed jury instruction stated, in part: "[I]f you find

that individuals jointly and simultaneously possessed the drugs

with the intent to share them amongst themselves as users, you may

                               -11-
not find the Defendant guilty of distribution, aiding and abetting

distribution, or possession with intent to distribute."

           The court instructed the jury: "[W]hen individuals come

into joint actual possession of a quantity of drugs that they

intend to keep for their own personal use, there is no 'intent to

distribute' under the law" (emphasis added).        Cormier objected to

the jury instruction on the grounds that it included the word

"actual" when describing joint possession.         The court overruled

Cormier's objection.

           The court further instructed the jury:

           The defendant has a constitutional right not
           to testify and no inference of guilt or
           anything else may be drawn from the fact that
           the defendant did not testify. . . . [F]or any
           of you to draw such an inference against this
           defendant would be wrong, indeed, it would be
           a violation of your oath as a juror. . . .
           [Y]ou do not have to accept the testimony of
           any witness if you believe that the witness
           was not credible. . . . Arguments and
           statements by lawyers are not evidence.

           The jury convicted Cormier on all counts.          Cormier was

sentenced to a total of 411 months imprisonment to be followed by

five   years    of   supervised    release.   Cormier   now   appeals   his

conviction.

                             II.    Discussion

           A.    Sufficiency of the Evidence

           Cormier begins by arguing that the jury had insufficient

evidence to find that he intended to distribute the drugs he


                                     -12-
obtained during the robberies. We review Cormier's challenges to

the sufficiency of the evidence de novo, examining the evidence in

the light most favorable to the Government. United States v. Hall,

434 F.3d 42, 49 (1st Cir. 2006).

              Taking the evidence in the light most favorable to the

government, it appears that Cormier gave some of the stolen drugs

to Finch, who was not physically present when the Dyer robbery

occurred, and Paquette, who was only tangentially involved in the

robberies.3     There was also testimony that Cormier traded pills to

Hanson to purchase marijuana.              In addition, Cormier directed that

some of the stolen marijuana be given to Simpson, who did not

participate      in     the       robberies,       to   pay    for     Finch's      bail.

Furthermore, the evidence shows that Cormier requested the help of

another person (Depka) in distributing drugs.                    Even though Depka

later refused to help, that refusal does not negate Cormier's

intent to distribute the drugs.                Cf. United States v. Dixon, 449

F.3d   194,    202-03      (1st    Cir.    2006)    (holding    that       a   sentencing

guidelines enhancement "turns on a defendant's subjective intent,

without   regard      to    factual       impossibility").           The   quantity   of

marijuana retained by Cormier -- at least two pounds -- although

not dispositive, at least suggests that it may not have been



3
  It   is well accepted that drugs may be distributed by giving them
away   for free; 18 U.S.C. § 841(a)(1) imposes no requirement that a
sale   take place. See, e.g., United States v. Washington, 41 F.3d
917,   919 (4th Cir. 1994) (collecting cases).

                                           -13-
intended only for personal use.             See United States v. Echeverri,

982 F.2d 675, 678 (1st Cir. 1993) ("We have repeatedly held, and

today reaffirm, that an intent to distribute drugs can legitimately

be inferred from factors such as quantity and purity."). Given the

extent   of    the    evidence,    we   believe     that    the   jury   reasonably

concluded beyond a reasonable doubt that Cormier intended to

distribute some of the drugs that he acquired, both to participants

and nonparticipants in the robberies.               Thus, we reject Cormier's

claim that the evidence was insufficient to prove his intent to

distribute drugs.

              B.   Jury Instructions

              As   an   analog    to    Cormier's      argument    regarding   the

sufficiency of the evidence, Cormier contends that the jury was

misinstructed on how it should consider the evidence in light of

United States v. Swiderski.            In Swiderski, the Second Circuit held

that when "two individuals simultaneously and jointly acquire

possession of a drug for their own use, intending only to share it

together, their only crime is personal drug abuse -- simple joint

possession, without any intent to distribute the drug further."

548   F.2d    at     450-51.      Swiderski     goes   on    to   explain   that   a

defendant's joint, simultaneous acquisition of drugs with another

does not bar a finding that the defendant intended to distribute

the jointly acquired drugs, but rather, that more evidence will be

needed to prove an intent to distribute.                    Id. at 450.     As the


                                         -14-
Second Circuit stated, "[w]hether such an inference [of intent to

distribute]      may   be    drawn     depends   upon    the      surrounding

circumstances, including the nature of the relationship (whether it

is commercial rather than personal), the quantity of the drug

(whether it is too large for personal use only), the number of

people involved, and statements or conduct on the part of the

defendants."     Id.

           Cormier's argument on this point is subject to plain

error review because his objection to the jury instructions was

made only at the pre-charge colloquy and not after the charge and

before deliberations.       See United States v. Moran, 393 F.3d 1, 13

& n.7 (1st Cir. 2004).      Cormier argues that it was plain error for

the district court to instruct the jury that, to negate intent,

Cormier needed to prove that he jointly and actually possessed

drugs with another.      Cormier contends that Swiderski is broader,

providing that a defendant's intent to distribute drugs cannot be

based   solely    on   evidence   of    either   joint   actual    or   joint

constructive possession of those drugs with a co-venturer -- i.e.

possession shared with an accomplice or lookout.                  There is a

dispute as to whether Cormier waived the objection. We will assume

there was no waiver4 and engage in plain error review.               We will


4
   The Government argues that Cormier waived his objection to the
jury instructions, and thus no review is possible. According to
the Government, Cormier said, "No objection" after the judge read
the charge, and thus intentionally waived his objection on the
issue. See United States v. Hansen, 434 F.3d 92, 100-01 (1st Cir.

                                     -15-
reverse if "(1) [] an error occurred (2)                 which was clear or

obvious and which not only (3) affected the defendant's substantial

rights, but also (4) seriously impaired the fairness, integrity, or

public    reputation   of   judicial   proceedings."       United   States   v.

Duarte, 246 F.3d 56, 60 (1st Cir. 2001).

            We have never expressly decided whether Swiderski is good

law in this circuit5 and we decline to do so now because our

resolution   of   Cormier's    challenge    to     the   sufficiency   of    the

evidence shows that Cormier cannot satisfy the fourth prong of

plain error review: the decision to not give Cormier's proposed

Swiderski instruction did not seriously impair the fairness of his

trial.    Cormier cannot satisfy this fourth prong because the jury

had sufficient evidence which showed beyond a reasonable doubt that

Cormier    intended    to   distribute     drugs    beyond    the   immediate

participants in each robbery, which would satisfy the intent to

distribute requirement of § 841(a)(1) even if we were to accept

Cormier's understanding of Swiderski as correct. See United States


2006). Cormier responds that although his objection was improperly
preserved, he did, in fact, object during the jury charge
conference. Cormier states that "No objection" was intended as a
response to the judge refusing the prosecutor's suggestion of an
additional charge.    Because it is unclear whether Cormier's
statement was an unequivocal waiver of his objection to the jury
instructions, we prefer to decide the issue on the merits.
5
  The only three cases in this circuit to have addressed Swiderski
found that it was inapplicable to the facts. See United States v.
Reid, 142 Fed. Appx. 479, 482 (1st Cir. 2005); United States v.
Rush, 738 F.2d 497, 514 (1st Cir. 1984); United States v. Taylor,
683 F.2d 18, 21 (1st Cir. 1982).

                                   -16-
v. Taylor, 683 F.2d 18, 21 (1st Cir. 1982) (finding Swiderski

inapplicable given that "the complex nature of the operation and

the amount of marijuana confiscated belies defendants' contention

that they did not intend to transfer the drugs to other persons").

Because we find the evidence sufficient to establish Cormier's

intent to distribute drugs, a jury instruction strictly tracking

the language in Swiderski would have been of little help to

Cormier, and as such, we cannot conclude that the failure to give

such an instruction impaired the fairness of the proceedings.

           C.    Expert Testimony

           Cormier next claims that it was inappropriate for the

court to admit the testimony of ATF Agent McSweyn regarding the

provenance of the weapons used in the robberies. We review a

district     court's    decision     to    admit        testimony     for   abuse   of

discretion.     See United States v. McGauley, 279 F.3d 62, 72 (1st

Cir. 2002).

           Fed.   R.    Evid.    702      allows    a    court   to    admit   expert

testimony regarding "scientific, technical, or other specialized

knowledge" so long as the testimony is "based upon sufficient facts

or data[,] . . .       the product of reliable principles and methods,

and . . .       the witness has applied the principles and methods

reliably to the facts of the case."            Fed. R. Evid. 703 states that

"facts or data need not be admissible" if they are "of a type

reasonably    relied    upon    by   experts       in    the   particular      field."


                                       -17-
Cormier argues that ATF Agent McSweyn's testimony regarding the

"interstate nexus" element of 18 U.S.C. § 922(g) was not admissible

under Fed. R. Evid. 702 because it did not concern specialized

knowledge, and that even if it did, the testimony failed to comply

with   Fed.   R.   Evid.   703   because   McSweyn    relied   only    upon

impermissible facts and data in stating his conclusions.

          In United States v. Corey, 207 F.3d 84 (1st Cir. 2000),

we rejected an identical argument.         We held that the "interstate

nexus" element of § 922(g) constituted specialized knowledge for

which expert testimony would be appropriate.           Id. at 88-89.    We

further found that the evidence relied upon by the ATF agent in

that case -- technical manuals, conversations with manufacturers,

and the expert's prior experience -- was evidence reasonably relied

upon by experts in the field.     Id. at 91-92.      In the present case,

ATF Agent McSweyn relied upon the same evidence as was relied upon

in Corey, but added to the mix dealer records, public and non-

public ATF records, and inspection of one of the firearms. Cormier

complains that ATF Agent McSweyn's testimony consisted only of a

restatement of the conclusions made in public records.           We agree

with Cormier that "an expert witness may not simply summarize the

out-of-court statements of others as his testimony." United States

v. Smith, 869 F.2d 348, 355 (7th Cir. 1989).         However, this is not

what happened here.    McSweyn not only consulted publicly available

records in making his conclusions about the manufacturing origin of


                                   -18-
the weapons, but he also looked to conversations with manufacturers

and research texts, and he inspected one of the weapons.                     We see no

reason    why       an    expert    in   firearms    identification       could    not

reasonably rely on ATF manufacturing records to determine the

provenance of a weapon.            See United States v. Ware, 914 F.2d 997,

1003    (7th    Cir.       1990)   ("[E]xperts      in   the   field    of   firearms

identification rely on [ATF publications and lists] with regard to

the    issue    of       interstate   transportation      of   firearms      and   such

reliance is reasonable.").               Thus, Cormier gives us no reason to

depart from our conclusion in Corey that an ATF agent, using

evidence reasonably relied upon by experts in that field, including

publicly available records, may testify as to the interstate nexus

element of a federal firearms offense.

               D.    Prosecutor's Opening and Closing Statements

               Lastly, Cormier calls our attention to comments made by

the prosecutor during her opening and closing statements, which

Cormier    construes         as    improperly    vouching      for   witnesses     and

criticizing his choice not to testify.               We have fashioned a three-

part test to determine whether a prosecutor's comments have so

"poisoned the well" that a new trial must be ordered.                          United

States v. Joyner, 191 F.3d 47, 54 (1st Cir. 1999).                     We consider:

               (1) whether the prosecutor's conduct was
               isolated and/or deliberate; (2) whether the
               trial court gave a strong and explicit
               cautionary instruction; and (3) whether it is
               likely that any prejudice surviving the


                                          -19-
           judge's instruction could have affected the
           outcome of the case.

Id.

           Cormier   argues     that    the   prosecutor    improperly   and

repeatedly   vouched   for     the     credibility   of    witnesses.     He

specifically points to the fact that the prosecutor said three

times during the opening that witnesses were "telling the truth."

Further, Cormier argues, the prosecutor again vouched for the

witnesses during her closing argument when she said that the

witnesses "are worthy of their belief."         Compounding these errors,

Cormier   argues,    were     the    prosecution's    comments    regarding

"Mr. Cormier's own words and actions" and "Mr. Cormier's own

credibility."   These comments, Cormier argues, were an indirect

criticism of his choice not to testify at trial.

           It is undisputed that the government is prohibited from

placing the "prestige of the United States behind a witness by

making personal assurances of credibility."                United States v.

Torres-Galindo, 206 F.3d 136, 140 (1st Cir. 2000). Likewise, it is

clearly established that a prosecutor may not comment upon a

defendant's choice to avail himself of his Fifth Amendment right to

not testify at trial.       Griffin v. California, 380 U.S. 609, 613

(1965); United States v. Roberts, 119 F.3d 1006, 1014 (1st Cir.

1997).    The Government conceded that some of the prosecutor's

statements vouched for certain witness' testimony. Furthermore, we

agree with the district court that the prosecutor's statements,

                                     -20-
although somewhat ambiguous, may have come "perilously close" to

criticizing Cormier's choice to not testify.                 Given Cormier's

frequent objections to these statements and that the prosecutor

continued to make them, these comments constitute a serious error

in judgment on the part of the prosecutor.6

           We     are    mindful,     however,   of    the   Supreme      Court's

"admonition      against    letting    the    guilty   go    free    to    punish

prosecutorial misconduct."          United States v. Auch, 187 F.3d 125,

133 (1st Cir. 1999) (citing United States v. Hasting, 461 U.S. 499,

506-07 (1983)).         To begin, the vigorous cross-examination of the

prosecution witnesses, the court's instructions7 to the jury to

disregard the prosecutor's improper comments, and the passage of

four days after the opening remarks were made, likely mitigated the

impact on the jury of the prosecutor's initial improper vouching.

See United States v. Rosales, 19 F.3d 763, 767 (1st Cir. 1994).

Our   concerns    with     the   prosecutor's    statement   on     closing   are

somewhat greater because of the possible cumulative effect of the

improper comments and the fact that the prosecutor had already been

censured for such comments during the opening. However, as we have

recommended, the court issued "final instructions to the jury


6
   Admirably, the Government conceded that at least some of the
prosecutor's comments were "to be avoided." Appellee's Br. at 49.
7
   Because there was a strong instruction at opening after the
vouching, this case does not raise the question of measuring
prejudice when there is vouching only at an opening statement which
is not followed by an explicit curative instruction.

                                       -21-
[that] were strong and clear" on their duty to disregard the

improper     comments    and   to   properly    weigh    the    credibility      of

witnesses.     United States v. Rodríguez-Estrada, 877 F.2d 153, 159

(1st Cir. 1989).     The fact that Cormier declined the court's offer

of an additional instruction is also indicative of the lack of

prejudice.    Furthermore, this was not a case where the prosecution

relied solely on the testimony of one or two witnesses, in which

vouching could have had a particularly strong impact on the jury.

Compare United States v. Manning, 23 F.3d 570, 575 (1st Cir. 1994)

(finding     that   improper    vouching      affected   a     case    where    two

prosecution witnesses had testified against the defendant and their

testimony     was   challenged      by   two     defense       witnesses)      with

Torres-Galindo, 206 F.3d at 141-42 (1st Cir. 2000) (finding that

vouching did not affect a case where there was consistent testimony

implicating the defendant).          Rather, the prosecution offered not

only   the   testimony    of   Cormier's      co-venturers,      but    also    the

testimony of victims of his robberies and other acquaintances, all

of   whom    testified    consistently       regarding   Cormier's       actions.

Finally, the prosecutor's statements regarding Cormier's choice not

to testify were so vague and oblique that it was unlikely that they

caused Cormier any real prejudice. Given the overwhelming evidence

which implicates Cormier in the crimes of which he has been

convicted, we cannot say that any prejudice surviving the curative

instructions would have affected the outcome of the trial.
