Amador  Irizarry-Sanabria,  Jos   Salvador  And jar,   and  Pedro

Infante-Ruiz  were convicted by a jury  in federal district court

for conspiracy  to import approximately 3000  pounds of marijuana

and for the possession of a firearm in relation to the commission

of  said narcotics offense, in  violation of 21  U.S.C.    952(a)

and 963, and 18 U.S.C.   924(c)(1), respectively.  All defendants

now  appeal.  Jos  Salvador And jar alleges that the evidence was

insufficient  to support  the jury's  verdict.   Amador Irizarry-

Sanabria  (1) challenges  the  sufficiency of  the evidence;  (2)

alleges that  the district court erroneously  instructed the jury

regarding the meaning of reasonable doubt; and (3) maintains that

the  district  court  abused  its discretion  in  precluding  the

defense  from presenting  certain impeachment  testimony.   Pedro

Infante-Ruiz alleges  (1) that the district  court misapplied the

United  States  Sentencing   Guidelines  (the  "Guidelines")   in

determining  his sentence;  and  (2) that  the jury  instructions

impermissibly reduced the government's  burden of proof at trial.

For  the  following  reasons,  we  vacate  the  conspiracy  and  
                                                   

924(c)(1)  convictions  of  Jos   Salvador And jar.    All  other

convictions are affirmed.
                                  

                          I.  BACKGROUND
                                    I.  BACKGROUND

          We  recite the facts in the light most favorable to the

government.  United States  v. Echeverri, 982 F.2d 675,  676 (1st
                                                  

Cir. 1993).  The  charges contained in the indictment  arose from

an unsuccessful  operation to  import narcotics into  Puerto Rico

                               -3-


from Colombia.  The pertinent facts occurred between September 24

and  September  30,  1991, beginning  with  the  co-conspirators'

efforts  to recruit William Linder ("Linder") to assist them in a

scheme  to import marijuana.   These facts came  to light because

Linder, unbeknownst  to the co-conspirators,  was a  confidential

informant working for the government.

          Linder had resided in  the town of Lajas,  Puerto Rico,

Papayo Ward, for nearly thirty years.  Linder's occupation at the

relevant  time  was selling  oysters  from  a kiosk  adjacent  to

Salvi's Tire Center  (the "Tire  Center").  The  Tire Center,  as

well  as the adjacent kiosk, was owned by Appellant Jos  Salvador

And jar  ("And jar"), whom  Linder  had known  for  approximately

twenty-eight years.  Linder  had become acquainted with Appellant

Pedro  Infante-Ruiz ("Infante")  because Infante  was  a frequent

customer  at his  oyster  stand.   Linder  knew Appellant  Amador

Irizarry-Sanabria ("Irizarry") because he  owned a fish market in

the nearby town of La Parguera.

          On September  24, 1991,  while Linder  was at  the Tire

Center, he noticed Infante  drive up.  After Infante  and And jar

had a  brief conversation, which  Linder could not  hear, And jar

told  Linder that  Infante  wanted to  see  him inside  the  Tire

Center.  Infante  and Linder  met alone in  And jar's office,  at

which time Infante  asked Linder if Linder would  use his boat to

retrieve  a load  of  drugs from  an  ocean rendezvous.    Linder

accepted  the proposition, and they agreed to meet later the same

day at the Tire Center.

                               -4-


          Linder then  left the  Tire Center and  informed Puerto

Rico Police  Agent Am lcar  Vargas ("Agent Vargas")  of Infante's

illegal offer.   Afterwards, he  returned to the  Tire Center  to

wait for Infante,  who eventually arrived with Irizarry.  Infante

then drove  them to a  house located  in the direction  of Barrio

Joyuda (the  "Barrio Joyuda House"), where  Federico Francisco de

la Paz (a.k.a.  "Freddie") was  waiting.  Also  present were  two

Colombian  nationals,  Alberto Enrique  Pineda-Wissman ("Pineda")

and  an unidentified individual.  And jar was not present at this

meeting.

          Pineda proceeded to  sketch out the plans  for the off-

shore drug pick-up.  The plan  called for Linder to take his boat

to a location near Mona Island, where he would retrieve the drugs

from a speed boat called "La Colombiana."  Pineda provided Linder

with a crude map of Mona Island, the coordinates for the intended

rendezvous  point, and a list  of the radio  frequencies on which

the co-conspirators planned to communicate.

          Because  Linder was  unsatisfied with  the map  of Mona

Island, Infante instructed Irizarry to get him a nautical  chart.

Irizarry and Linder then  proceeded to Lucas Marine Shop  in Cabo

Rojo, where  they purchased a  nautical ruler, and  La Pescader a

Rosa, where they found  an appropriate chart.  Irizarry  paid for

both items.

          On their  way back to the Barrio Joyuda House, Irizarry

informed  Linder that  he was to  pick up  a 3,000  pound load of

marijuana  and  offered him  $100,000 for  his  efforts.   At the

                               -5-


Barrio Joyuda  House, Linder was given $800  to purchase supplies

for the  trip.    Linder  then  left the  house  and  bought  the

necessary supplies.   Before he  returned home, he  briefed Agent

Vargas on the day's events.

          The following  day, September 25, 1991,  Linder went to

the  Tire Center,  where  And jar instructed  him  to return  the

following  day to  meet Infante.   The  next day,  as instructed,

Linder returned  to the Tire  Center.   Infante was late  for the

scheduled  meeting,  so  And jar,  at  Linder's  request,  called

Infante's cellular phone to determine his whereabouts.  After the

call,  And jar assured  Linder  that Infante  would arrive  soon.

Shortly  thereafter,  accompanied   by  Irizarry,  Infante  drove

through the Tire  Center's back entrance.  Infante ordered Linder

to  get in  the vehicle  quickly so  that he  would not  be seen.

Before proceeding to the  Barrio Joyuda House, Infante instructed

And jar to  move Linder's car from  the front to the  back of the

Tire Center.

          When  Linder,  Infante,  and  Irizarry  arrived at  the

Barrio Joyuda House, the  same group present at the  September 24

meeting was already  assembled.  They discussed  revisions in the

plans, and Linder  told the group that he would  require a gun if

he was to  make the journey  alone.   After a brief  consultation

with  Infante and Freddie,  Irizarry left the  house and returned

shortly  with a  .357 Ruger  revolver, which  he gave  to Linder.

After the meeting  dissolved, Linder met  with the local  police,

who copied the weapon's serial number.

                               -6-


          Before his  departure on  the evening of  September 26,

Linder  met with Lt. Gonz lez,  a local police  officer, and Drug

Enforcement Administration agent  Jos  Morales ("Agent Morales").

Linder  informed them of the specifics of his trip, and the three

agreed to  meet the  following day  at a  spot near  Mona Island.

Linder surrendered the revolver to the officers at this time.

          Linder  arrived  at  Mona  Island  on  the  morning  of

September 27.  He  was met later that day by  Lt. Gonz lez, Agent

Morales,  and several  other law  enforcement personnel.   Linder

left that night for  the rendezvous, which was scheduled  to take

place the following afternoon.

          Although Linder arrived at  the rendezvous point at the

appointed  hour, the Colombian boat was nowhere  to be seen.  The

boat never appeared, and attempts to communicate with it by radio

were  unavailing.  It was  close to midnight  when Linder finally

decided to head back to Mona Island.  The seas were rough, and he

was having  engine and  radio problems.   Eventually, his  engine

quit altogether.  Linder's boat remained adrift until a large tug

boat stopped to help  and called the Coast Guard  for assistance.

The  Coast Guard arrived and  brought Linder on  board.  Although

they tried to tow his boat back to Mona Island, it sank along the

way.

          When Linder eventually arrived  back at La Parguera, he

recounted  the  events  to   Irizarry,  who  explained  that  the

Colombian boat had suffered  engine problems and had  been unable

to make  the trip.  During the following days, Linder and the co-

                               -7-


conspirators  met at the Tire Center, where they assured him that

they would get him another boat.  Infante cautioned Linder not to

tell anyone  about the failed  mission and specifically  told him

not  to  communicate  over   the  telephone.    Instead,  Infante

instructed Linder, "Anytime you want to say something to me, tell

[And jar].  [And jar] will call me and I get with you [sic]."

          Several  days later,  while  Linder was  at the  oyster

kiosk, And jar told him, "My friend came to pick  up the gun.  He

was looking for the gun.  I  told him he better go to Mona Island

and look in the mouth of a shark, and he might find it."

          Subsequently,   the   appellants   were  indicted   and

convicted in  federal court on  charges of  conspiracy to  import

marijuana  and  possession  of  a  firearm  in  relation  to  the

commission of the offense.

                 II.  SUFFICIENCY OF THE EVIDENCE
                           II.  SUFFICIENCY OF THE EVIDENCE

          Both  And jar and  Irizarry  allege that  the proof  at

trial was insufficient to support their convictions.

          A.  Standard of Review
                    A.  Standard of Review
                                          

          The  standard of  review governing  a challenge  to the

sufficiency of  the evidence is  well established.   An appellate

court must  determine whether a  rational jury  could find  guilt

beyond a reasonable doubt.   Echeverri, 982 F.2d at 677;   United
                                                                           

States  v. Garc a, 983  F.2d 1160, 1163-64  (1st Cir. 1993).   In
                           

making this  determination, the reviewing court  must examine the

evidence,  together with  all inferences  that may  be reasonably

drawn  from it, in the  light most favorable  to the prosecution.

                               -8-


Echeverri,  982 F.2d  at 677.   Furthermore, the  reviewing court
                   

does  not   evaluate  witness   credibility,  but   resolves  all

credibility issues in favor of the verdict.   Garc a, 983 F.2d at
                                                              

1164  (quoting United States v.  Batista-Polanco, 927 F.2d 14, 17
                                                          

(1st Cir. 1991)).  "The evidence may  by entirely circumstantial,

and need  not exclude  every reasonable hypothesis  of innocence;

that   is,   the   factfinder   may   decide   among   reasonable

interpretations of  the evidence."  Batista-Polanco,  927 F.2d at
                                                             

17.  Nevertheless, "[i]f  the 'evidence viewed in the  light most

favorable  to  the  prosecution   gives  equal  or  nearly  equal

circumstantial  support  to a  theory of  guilt  and a  theory of

innocence  of the  crime  charged,' this  court must  reverse the

conviction.  This  is so because .  . . where an  equal or nearly

equal theory of guilt and  a theory of innocence is supported  by

the evidence viewed in  the light most favorable to  the verdict,

'a  reasonable  jury  must  necessarily  entertain  a  reasonable
                                                            

doubt.'"   United  States v.  S nchez, 961  F.2d 1169,  1173 (5th
                                               

Cir.) (citations omitted),  cert. denied, 113 S.  Ct. 330 (1992).
                                                  

With  the scope  of  our  review thus  defined,  we  move to  the

appellants' claims.

          B.  Conspiracy
                    B.  Conspiracy
                                  

          To establish a  conspiracy conviction, the  prosecution

must prove, inter alia, that  the defendant entered an  agreement
                                

to commit the substantive  offense, and that the defendant  was a

voluntary participant in the conspiracy.   Echeverri, 982 F.2d at
                                                              

679.  The government must prove that the defendant possessed both

                               -9-


"intent to  agree and intent to commit  the substantive offense."

Garc a,  983 F.2d at 1165 (citation omitted).  However, "[d]ue to
                

the  clandestine  nature   of  criminal  conspiracies,  the   law

recognizes  that the illegal agreement  may be either 'express or

tacit' and that a '"common purpose  and plan may be inferred from

a development and collocation  of circumstance."'"  United States
                                                                           

v. S nchez, 917 F.2d 607, 610 (1st Cir. 1990)(citations omitted),
                    

cert. denied,  111 S.  Ct. 1625  (1991).   "Mere presence  at the
                      

scene and close association  with those involved are insufficient

factors alone;  nevertheless, they  are relevant factors  for the
                                                          

jury."  S nchez, 961  F.2d at 1174 (5th Cir.)  (citation omitted)
                         

(emphasis in original).

          Irizarry maintains  that the  evidence  against him  is

insufficient because it consisted only of Linder's uncorroborated

testimony.   While  it  is true  that  much of  the  government's

evidence consisted of the largely uncorroborated testimony of the

confidential   informant,   Linder,  Irizarry's   argument  fails

nevertheless.   As we noted  above, an appellate  court reviewing

the  sufficiency of  the  evidence must  resolve all  credibility

determinations in favor of  the verdict.  This rule  of appellate

review  applies   equally  when  the  evidence   centers  on  the

uncorroborated testimony of a  confidential informant, so long as

the testimony is not "'incredible or insubstantial on its face.'"

United States v. G mez-Pab n,  911 F.2d 847, 853 (1st  Cir. 1990)
                                      

(holding  that  evidence  was  not  rendered insufficient  merely

because it consisted largely of the uncorroborated testimony of a

                               -10-


paid informer) (quoting United  States v. Aponte-Su rez, 905 F.2d
                                                                 

483, 489 (1st Cir. 1990)).

          Given that  we resolve any credibility  issues in favor

of  the  verdict,  we  find  that Irizarry's  sufficiency-of-the-

evidence  challenge  fails  because  the  record  contains  ample

support for his conspiracy  conviction.  A reasonable jury  could

infer from  Linder's testimony that Irizarry  was deeply involved

in the  entire  operation.   According  to Linder,  Irizarry  was

present at the Barrio Joyuda  House when the Colombians discussed

the radio frequencies, code names, and coordinates that would  be

used for the drug  run.  Moreover, Irizarry procured  the firearm

for Linder  and  offered  Linder  $100,000 for  his  services  in

retrieving the  marijuana from the off-shore  rendezvous with the

Colombians.    A  jury  hearing this  evidence  could  reasonably

conclude that Irizarry was a voluntary participant in an unlawful

scheme  to  import marijuana.    We therefore  conclude  that the

evidence  was sufficient  to  convict Irizarry  of conspiracy  to

import narcotics.

          And jar also maintains  that his conspiracy  conviction

is unsupported by the  record.  Specifically, he claims  that the

evidence at trial showed no more than "mere presence" at the Tire

Center.     Recently,  we  noted   that  "the  culpability  of  a

defendant's presence hinges upon whether the circumstances fairly

imply participatory  involvement.  In other  words, a defendant's

'mere presence' argument will fail in situations where the 'mere'

is  lacking."   Echeverri,  982 F.2d  at  678.   Upon  a thorough
                                   

                               -11-


scrutiny of the record, we find that the evidence is insufficient

to  establish   anything  more   than  And jar's   mere  presence

throughout the conspiracy.  That is, the evidence is insufficient

as a matter of law to have permitted  a jury to conclude beyond a

reasonable doubt that And jar was a voluntary  participant in the

importation conspiracy.

          The    evidence    relating   to    And jar's   alleged

participation  in  the conspiracy  can  be  fairly summarized  as

follows:   According  to  Linder, And jar  arranged the  original

meeting between  Linder and  Infante, during which  Infante asked

Linder  to  participate  in  the  marijuana  importation  scheme.

Though And jar  was  not  present,  he allowed  Infante  to  talk

privately  with Linder  in his  office at  the Tire  Center.   No

evidence  was presented as  to whether  And jar knew  the subject

matter  of  this conversation.    And jar  also orchestrated  the

September 26 meeting between Linder and Infante, and when Infante

was  late for  this  meeting, And jar  called Infante's  cellular

phone  and informed  him  that Linder  was  waiting at  the  Tire

Center.    When  Infante  arrived,  he  ordered  And jar  to move

Linder's car to the back of the Tire Center.   Following Linder's

ill-fated  voyage   to  Mona  Island,  the  co-conspirators  used

And jar's Tire  Center several  times to  meet and discuss  their

plans.    Linder  testified  that during  one  of  these meetings

And jar had remarked, "My  friend came to pick up  the gun . .  .

and I told him that he  better go to Mona Island and look  in the

mouth of a shark, [and]  he might find it."  After  Linder's boat

                               -12-


had  sank, Infante ordered Linder to refrain from using the phone

to contact him.  Instead,  he told Linder, "Any time you  want to

say something to me, tell [And jar].  [And jar]  will call me and

I get [sic] with you."

          The  prosecution   was  required  to   prove  beyond  a

reasonable  doubt  that  And jar  was  a  voluntary  and  knowing

participant in the conspiracy.  More specifically, the government

had  to establish  (1)  that And jar  intended  to agree  to  the

importation scheme and  (2) that he intended  to import marijuana

into  the United  States.   From the  evidence presented,  a jury

could permissibly  infer that, at  least after the  fact, And jar

was aware of many of the details of the bungled attempt to import

marijuana.  The  evidence is insufficient, however, to permit the

jury to have found that And jar had the requisite specific intent

to import marijuana.   Although And jar arranged several meetings

between Linder and Infante, And jar was not present at any of the

co-conspirators' critical planning meetings at  the Barrio Joyuda

House.  In fact,  the prosecution did not introduce  any evidence

suggesting that  And jar was aware that the  meetings concerned a

pending drug  deal.  We  realize, of course,  that after-the-fact

knowledge of an illegal conspiracy and presence at  the operative

locations  are  relevant  factors   for  the  jury  to  consider.

Nevertheless, these factors alone are insufficient to establish a

conspiracy conviction.

          We  do  not look  at  the record  through  rose colored

lenses; rather,  we canvass the record  dispassionately, and base

                               -13-


our decision  on proven  facts, leaving aside  undue speculation.

While  And jar's actions are consistent with those of a low level

participant or  "middle-man" in  the importation scheme,  they do

not  demonstrate his participation  with the  certainty necessary

for a criminal conviction.  And jar's actions, when seen in light

of the events following  Linder's voyage, offer equal support  to

both And jar's mere presence  theory and the prosecution's theory

that And jar was knowingly acting as a facilitator and go-between

in  the conspiracy,  which  of  course constitutes  participatory

involvement.    In  this  circumstance,  we  must  find  that the

evidence was insufficient to sustain the conviction.  When a jury

is confronted, as here, with equally persuasive theories of guilt

and innocence it cannot rationally find guilt beyond a reasonable

doubt.   We therefore vacate And jar's  conviction for conspiracy

to import marijuana.

          C.  The Firearm Conviction
                    C.  The Firearm Conviction
                                              

          And jar also  alleges that the evidence  against him is

insufficient  to  support  his  conviction for  possession  of  a

firearm  in relation to the commission of a narcotics offense, in

violation  of 18  U.S.C.     924(c)(1).1    We  agree.    Section

924(c)(1) provides sentencing enhancements if a defendant "during

and  in relation  to any  crime of  violence or  drug trafficking

crime[,]  .  .  .  uses  or carries  a  firearm."    18  U.S.C.  

924(c)(1).  "By its  terms, the statute requires the  prosecution

                    
                              

1  For  reasons unknown,  the government failed  to address  this
issue in its brief on appeal.

                               -14-


to make two  showings.  First,  the prosecution must  demonstrate

that the defendant 'use[d]  or carrie[d] a firearm.'   Second, it

must prove that the use  or carrying was 'during and in  relation

to' a 'crime of  violence or drug trafficking crime.'"   Smith v.
                                                                        

United States, 113 S. Ct. 2050, 124 L.Ed.2d 138, 147 (1993).
                       

          Both elements  are absent  here.   First,  there is  no

evidence that And jar  used or carried  the gun the  conspirators

gave to  Linder.   Second,  there  was insufficient  evidence  to

convict And jar of a crime of violence or drug trafficking crime.

Consequently,   liability  under     924(c)(1)  is  inapplicable.

Accordingly,  we  vacate  his  conviction  for  the     924(c)(1)

firearms count as well.

                      II.  JURY INSTRUCTIONS
                                II.  JURY INSTRUCTIONS

          Both   Irizarry   and   Infante   challenge   the  jury

instructions  given  by the  district  court.   However,  because

neither  appellant  raised an  objection  to the  jury  charge at

trial,  we review the instructions only for plain error, that is,

"'errors so  shocking that they seriously  affect the fundamental

fairness  and basic integrity' of  the trial."   United States v.
                                                                        

Mej a-Lozano,  829  F.2d  268,  272  (1st  Cir.  1987)  (citation
                      

omitted); see also Fed. R. Crim. P. 30 and  52(b).  We gauge each
                            

challenged instruction in the  context of the charge as  a whole,

not  in isolation.   United States v.  Boylan, 898 F.2d  230, 244
                                                       

(1st Cir. 1990).

          A.  Definition of Reasonable Doubt
                    A.  Definition of Reasonable Doubt
                                                      

          Irizarry   contends   that  the   court's  instructions

                               -15-


regarding the  definition of  reasonable doubt  constituted plain

error.  The court instructed the jury that:

            a reasonable doubt is a  doubt based upon
            reason and  common sense.  Proof beyond a
            reasonable  doubt   must,  therefore,  be
            proof of such a convincing character that
            a reasonable person would not hesitate to
            act upon it.
                              . . .
              So if you, the jurors,  after a careful
            and  impartial  consideration of  all the
            evidence  in the  case have  a reasonable
            doubt, it  means,  then, that  you  would
            hesitate to act  and find the  defendants
            guilt [sic]  of the  charge, and  if that
            happens, therefore, you must acquit.

          We have  repeatedly warned against attempting to define

reasonable doubt,  noting that  "[m]ost efforts  at clarification

result  in further obfuscation of the concept."  United States v.
                                                                        

Campbell, 874 F.2d 838, 843  (1st Cir. 1989) (citations omitted).
                  

Further, "[m]any definitions  reduce the burden  of proof on  the

government  by expanding  the  degree of  doubt permissible,  and

consequently  such  definitions  result  in  increased  appellate

litigation."  Id. (citations  omitted).  Nevertheless, a district
                           

court does not necessarily  commit reversible error by attempting

to  define the concept  of reasonable  doubt for  the jury.   See
                                                                           

United  States v.  Rodr guez-Cardona,  924 F.2d  1148, 1160  (1st
                                              

Cir.), cert. denied, 112 S. Ct. 54 (1991).  "[O]ur experience has
                             

been that even imperfect formulations usually meet constitutional

requirements when viewed  in the context  of the entire  charge."

Watkins  v.  Ponte, 987  F.2d 27,  32  (1st Cir.  1993) (citation
                            

omitted).  Therefore, appellate courts must tolerate a reasonable

range of expression.  Id.
                                   

                               -16-


          When   evaluating  a  district  court's  definition  of

reasonable  doubt,  an  appellate  court's  ultimate  concern  is

whether the instruction has a tendency to reduce the government's

burden of proof at trial.  See United States v. Nolasco, 926 F.2d
                                                                 

869, 871  (9th  Cir.) ("The  challenge confronting  a court  that

would  define reasonable  doubt  is to  avoid  language that  may

'mislead the jury into  finding no reasonable doubt when  in fact

there  was some.'"), cert. denied, 112 S. Ct. 111 (1991) (quoting
                                           

Holland v. United States, 348 U.S. 121, 140 (1954)).  "A criminal
                                  

defendant  is  entitled  to  an   instruction  that  '"adequately

apprise[s]   the  jury  of   the  reasonable  doubt  standard."'"

Campbell,  874 F.2d at 842 (citation omitted).  The United States
                  

Supreme Court  has suggested that an  acceptable definition would

define reasonable doubt as "the  kind of doubt that would make  a

person hesitate to act."   Holland, 348 U.S. at  140.  Deviations
                                            

from  the  "hesitate  to  act" language  have  often  constituted

reversible error, especially where the language likens reasonable

doubt to doubt which would cause one to act, rather than hesitate
                                                                           

to act.   See, e.g., United States v. Noone, 913 F.2d 20, 29 n.14
                                                     

(1st Cir. 1990), cert. denied, 500 U.S. 906 (1991); United States
                                                                           

v. Col n-Pag n, 1  F.3d 80, 81 (1st  Cir. 1993) (Where  the court
                        

defined "guilt beyond  a reasonable  doubt" as "proof  of such  a

convincing character that a person . . . would be willing to rely

and  act  upon  it,"   it  committed  plain  error  because   the

instruction may have given the jury the incorrect impression that

it could convict  the defendant  "upon the basis  of evidence  no

                               -17-


stronger  than   might  reasonably  support  a   decision  to  go

shopping.").

          In  Noone,  913  F.2d  at  29  n.14,  we   approved  an
                             

instruction nearly identical to the one under consideration here,

and  noted  that  the  contested  language  was  essentially  the

converse of  the accepted  "hesitate to  act"  formulation.   The

instruction here says that  "a reasonable doubt is a  doubt based

upon  reason and common sense.   Proof beyond  a reasonable doubt

must, therefore, be proof  of such a convincing character  that a

reasonable  person would  not  hesitate to  act  upon it."    The

Supreme  Court has suggested that a reasonable doubt is one which

would cause a reasonable person to  hesitate to act.  As we noted

in  Noone, the language here  is essentially the  converse of the
                   

Supreme  Court's formulation --  that is,  if a  reasonable doubt

makes  a reasonable  person  hesitate  to  act,  proof  beyond  a

reasonable doubt is  proof upon which  a reasonable person  would

not hesitate  to act.   While we are concerned  with all district

court efforts  to define reasonable doubt,  especially those that

deviate from  the Supreme Court's "hesitate to  act" language, we

nevertheless   do   not  find   that   the  present   formulation

impermissibly  shifted the  government's burden  of proof.   This

conclusion  is buttressed by the  fact that the jury instructions

also  included the permissible  "hesitate to act"  language.  The

court instructed: "So  if you,  the jurors, after  a careful  and

impartial  consideration of all the  evidence in the  case have a

reasonable  doubt, it means, then, that you would hesitate to act

                               -18-


. . .  and if that  happens, therefore, you  must acquit."   This

instruction   tracked  the  Supreme   Court's  formulation,  and,

consequently, it decreased the likelihood  that the instructions,

as a whole, mislead the jury.  We think these  instructions, as a

whole,  adequately apprised the jury of the gravity of the proof-

beyond-a-reasonable-doubt standard, and, therefore, we cannot say

that the instruction was plainly erroneous.

          B.  Reference to "Guilt or Innocence"
                    B.  Reference to "Guilt or Innocence"
                                                         

          Infante argues  that the district court's  reference to

the  defendants' "guilt  or innocence"  in the  jury instructions

constituted plain error.

          The jury instructions at issue read as follows:

              I caution you[,] members of the jury[,]
            that you are here to  determine the guilt
            or  innocence  of  the  accused  from the
            evidence in  the  case.   You  know  that
            these defendants are not on trial for any
            other act  or any other  conduct that  is
            not alleged in this Indictment.

              Neither are you called upon to return a
            verdict as to the  guilt or innocence  of
            any other person or persons not  on trial
            here.   So  you  are not  being asked  to
            decide  the case  of Felipe  Francisco or
            the case of Mr. Pineda-Wissman.

Infante claims that the references to the "guilt or innocence" of

the  defendants  diminished  the  presumption  of  innocence  and

impermissibly reduced the government's  burden of proof at trial.

He contends  that the language may  have confused the  jury as to

the  proper standard of proof,  noting that a  defendant is never

required to  prove his innocence.  He  points out that jurors are

called upon only to decide whether the prosecution has proven the

                               -19-


defendant  guilty  beyond a  reasonable  doubt,  not whether  the

defendant is innocent.

          We have previously warned district courts against using

a "guilt  or innocence"  comparison.   United States v.  Mendoza-
                                                                           

Acevedo,  950 F.2d  1,  4 (1st  Cir. 1991).    Faced with  nearly
                 

identical  jury  instructions,  we  noted that  "[w]hen  a  court

repeatedly  tells jurors  that the  question is  one of  guilt or

innocence,  it  risks  undercutting the  government's  burden  by

suggesting that  they should  find the  defendant guilty  if they

think  he  is  not  innocent--regardless of  how  convincing  the

government's proof has been."   Id.  We repeat here that,  due to
                                             

the risks of misleading the jury, district courts  should refrain

wherever possible from using a "guilt or innocence" comparison in

their jury instructions.

          Despite this admonishment, however, we need not reverse

the defendants'  convictions.  As in  Mendoza-Acevedo, our review
                                                               

of  the entire charge convinces us "that any confusion engendered

by  the  inappropriate references  to  'guilt  or innocence'  was

offset  by  the  court's  careful  and  clear  discussion  of the

presumption of  innocence and the government's  burden of proof."

Id. (citations omitted).  The court informed the jury that "[t]he
             

law  presumes a  defendant to be  innocent of  a crime.   Thus, a

defendant,  although  accused,  begins  the trial  with  a  clean

slate."  It  further charged  the jury that  "the presumption  of

innocence alone is sufficient to acquit the defendant, unless the

jurors are satisfied beyond a reasonable doubt of the defendant's

                               -20-


guilt after  a careful  and  impartial consideration  of all  the

evidence  in the  case."   In closing,  the court  instructed the

jurors   that  "[if   they],  after   a  careful   and  impartial

consideration  of  all   the  evidence  in  the  case[,]  have  a

reasonable doubt,  it means  . .  . [they]  must acquit."   These

instructions were adequate to  ensure that the jury was  informed

of  the  government's  burden  of  proof  at  trial  and  of  the

presumption  of  innocence  cloaking criminal  defendants.    We,

therefore, can find no  plain error in the district  court's jury

instructions.

         III.  INFANTE'S SENTENCING GUIDELINES CHALLENGE
                   III.  INFANTE'S SENTENCING GUIDELINES CHALLENGE

          Infante claims  that the district  court misapplied the

United  States Sentencing Guidelines in determining his sentence.

Specifically, he contends that the  district court erred when  it

found  that he was a "leader or organizer" and consequently added

four  points  to his  base  offense level,  pursuant  to U.S.S.G.

  3B1.1(a).2

          Factbound  matters related to  sentencing, such  as the

district  court's determination  of  a defendant's  "role in  the

offense,"  need  only be  supported  by  a preponderance  of  the
                    
                              

2  U.S.S.G.   3B1.1 states:

              Based  on the  defendant's role  in the
            offense,  increase  the offense  level as
            follows:

              (a)  If the defendant  was an organizer
            or  leader  of a  criminal  activity that
            involved five or more participants or was
            otherwise   extensive,   increase  by   4
            levels.

                               -21-


evidence and will be  set aside on  appeal only for clear  error.

United States v. Corcimiglia, 967 F.2d 724, 726 (1st Cir. 1992).
                                      

          The Guidelines suggest that the sentencing court should

consider  the  following  factors  when  determining whether  the

defendant was a leader or organizer:

            [T]he   exercise   of   decision   making
            authority, the nature of participation in
            the  commission  of   the  offense,   the
            recruitment  of accomplices,  the claimed
            right to a larger  share of the fruits of
            the crime, the degree of participation in
            planning or organizing  the offense,  the
            nature and scope of the illegal activity,
            and the degree  of control and  authority
            exercised over others.

U.S.S.G.   3B1.1, comment. (n.4).

          Infante contends that he could not have been the leader

or organizer because the entire deal was clearly run by Francisco

de la Paz.   This  contention, however, overlooks  the fact  that

"[t]here can, of course, be more than one person who qualifies as

a  leader or organizer of a  criminal association or conspiracy."

U.S.S.G.     3B1.1, comment.  (n.3).   Our  review of  the record

convinces  us that  although Francisco  de la  Paz may  have been

running the show, the  district court did not commit  clear error

in  determining  that  Infante  had  a  leadership  role  in  the

operation.   After  the  sentencing hearing,  the district  court

stated:

              I  am now  more  convinced  than  ever,
            after having  heard the testimony  of Mr.
            Pedro Infante, that Mr. Pineda  served as
            the intermediary.  He was the  person who
            had  the contacts.    The  drug deal  was
            being arranged, mainly, mainly  on behalf
            of  Francisco de  la Paz,  also known  as

                               -22-


            Freddy.

              His personal contact, or principal man,
            was Mr. Infante-Ruiz,  and in that  sense
            he   was  the   leader,   a  leader   and
            organizer.
                              . . .
            [T]his  defendant   [Infante]  assumed  a
            leader/organizer  role in  the commission
            of the instant  offense as he  negotiated
            the importation scheme with the Colombian
            drug source through  an intermediary  who
            is also a codefendant,  was aware at  all
            times  as to  the logistical  elements of
            the    intended    importation    scheme,
            recruited   at   least    one   of    the
            codefendants  to  take   charge  of   the
            supportive  services to  include securing
            the  boat,  captain,  and individuals  to
            assist in the  importation, storage,  and
            subsequent distribution  of the marijuana
            load, and, finally, provided  payments to
            the  confidential   informant  to  assure
            readiness of the vessel to be used in the
            rendezvous with the mother ship.

We  find  that  the  district  court's  factual  conclusions  are

supported by  the record and fully justify its determination that

Infante  was a  leader  or  organizer  in  the  conspiracy.    We

therefore affirm Infante's sentence.

                   IV.  THE EVIDENTIARY RULING
                             IV.  THE EVIDENTIARY RULING

          Irizarry contends  that the district  court abused  its

discretion  when it  excluded  the testimony  of defense  witness

Humberto  Hern ndez-L pez  ("Hern ndez").   In  order  to impeach

Linder's  credibility, the  defense  intended  to have  Hern ndez

testify  regarding  an incident  in  which  Linder had  allegedly

broken a promise he had made to Hern ndez.  The incident involved

Linder's alleged failure to pay for some fishing nets that he had

apparently purchased from Hern ndez on credit.  Although the jury

                               -23-


had already learned of the incident through the defense's  cross-

examination  of Linder,  the  defense desired  to have  Hern ndez

testify as to his version of the event.

          It  is  well settled  that  a  party  may  not  present

extrinsic evidence of specific instances of conduct  to impeach a

witness on a  collateral matter.   United States  v. Tejada,  886
                                                                     

F.2d 483, 487 (1st Cir. 1989); Fed. R. Evid. 608(b).3   "A matter

is considered collateral if 'the matter itself is not relevant in

the litigation  to establish  a  fact of  consequence .  . .  .'"

United  States  v.  Beauchamp, 986  F.2d  1,  4  (1st Cir.  1993)
                                       

(quoting 1 McCormack on Evidence   45, at 169 (4th ed. 1992)).
                                          

          Here,  the incident  relating to  the fishing  nets was

only  relevant  to impeach  the credibility  of  Linder.   It was

irrelevant to the  substance of  the case --  the conspiracy  and

firearms  charges --  and  was, therefore,  a collateral  matter.

Consequently,  the district  court did  not abuse  its discretion

                    
                              

3  Rule 608 provides in part:

            (a)  Opinion  and reputation evidence  of
                                                               
            character.  The  credibility of a witness
                                
            may be attacked or supported  by evidence
            in the form of opinion or reputation, but
            subject  to these  limitations:   (1) the
            evidence may refer only to  character for
            truthfulness or untruthfulness . . . .
            (b)    Specific  instances of  conduct.--
                                                             
            Specific  instances of  the conduct  of a
            witness,  for the purpose of attacking or
            supporting the witness' credibility . . .
            may not be proved by  extrinsic evidence.
            They may, however,  in the discretion  of
            the court, if  probative of  truthfulness
            or  untruthfulness,  be inquired  into on
            cross-examination of the witness . . . .

                               -24-


when  it   excluded  the  testimony  of   Hern ndez  and  limited

discussion of  the fishing net  incident to the  defense's cross-

examination of Linder.4

                          V.  CONCLUSION
                                    V.  CONCLUSION

          For  the foregoing  reasons, And jar's  convictions are

vacated.  All other convictions are affirmed.
                                                      

                    
                              

4   Irizarry also  contends, in  the alternative,  that Hern ndez
should  have  been  allowed   to  offer  opinion  and  reputation
testimony regarding Linder's  character for  truth and  veracity.
The  district court  excluded this  testimony after  it concluded
that Hern ndez was "not  really acquainted with Linder"  and thus
lacked  sufficient knowledge  to proffer  an opinion  of Linder's
character.   This  conclusion  contains adequate  support in  the
record and does not constitute an abuse of discretion.
