    UNITED STATES OF AMERICA,
    Plaintiff-Appellee,
    VERSUS
    CLAUDE HARRIS ANDREWS,
    Defendant-Appellant.
    __________________________________________________
    Appeal from the United States District Court
    for the Southern District of Mississippi
    __________________________________________________
    (June 7, 1994)
    Before DUHÉ and EMILIO M. GARZA, Circuit Judges, and STAGG,*
    District Judge.
    EMILIO M. GARZA, Circuit Judge.
    Claude Harris Andrews appeals his conviction for possession of
    marijuana with intent to distribute, in violation of 21 U.S.C.
    § 841(a)(1) (1988), and importation of marijuana, in violation of
    21 U.S.C. §§ 952, 960.        Andrews contends that he is entitled to a
    new trial because (a) the district court erroneously admitted
    evidence which was seized during an unregulated inventory search of
    his car, in violation of the Fourth Amendment; (b) the district
    court erroneously admitted into evidence statements which Andrews
    made       to   law    enforcement   officers     without   knowingly   and
    intelligently waiving his rights under Miranda v. Arizona, 384 U.S.
    *
    District Judge of the Western District of Louisiana, sitting by
    designation.
    436, 
    86 S. Ct. 1602
    , 
    16 L. Ed. 2d 694
    (1966); (c) the prosecutor
    made improper comments at trial; (d) the district court failed to
    instruct the jury not to convict Andrews of importation unless he
    knowingly brought marijuana into the United States; (e) Andrews
    received ineffective assistance of counsel at trial; and (f) in the
    alternative, the cumulative effect of all of the foregoing errors
    rendered   Andrews'   trial    fundamentally      unfair.   Finding   no
    reversible error, we affirm.
    I
    Our discussion of the issues raised on appeal requires only a
    partial statement of the facts. The United States Drug Enforcement
    Administration ("DEA") received a tip that the tugboat Concord was
    bound for the port at Pascagoula, Mississippi, carrying a cargo of
    either marijuana or cocaine from Panama.       When the Concord arrived
    at a small, secluded boatyard in Pascagoula, DEA and United States
    Customs Service agents began covert surveillance of the boat.
    Andrews was waiting at the dock when the Concord arrived, and
    he told a Customs agent, who was posing as a uniformed Customs
    inspector, that he was the front man for a tug boat operation which
    would ferry barges from New Orleans to Puerto Rico.         Andrews told
    the agent that he was having some repairs done on the Concord at
    Pascagoula, including draining and scraping the fuel tanks.
    Thereafter,   DEA   and   Customs   agents    maintained   continual
    surveillance of Andrews when he was away from the dock and the
    Concord.   Around 2:00 a.m. on the third day after the Concord
    docked at Pascagoula, after following Andrews as he visited several
    -2-
    local drinking establishments, federal agents noticed that Andrews
    was driving erratically, and reported the situation to local
    police.     Officer Doug Adams of the Moss Point Police Department
    ("MPPD") arrived shortly and stopped Andrews. After Andrews failed
    several field sobriety tests, Adams arrested him for driving under
    the influence of alcohol ("DUI").
    At    the   scene   of   the   arrest,   Adams   conducted   a    routine
    inventory    search    of   Andrews'   vehicle,   finding   among     Andrews'
    personal effects a red spiral notebook containing two diagrams and
    several names.1       Adams also found a radio frequency detector))an
    electronic device used to detect radio transmissions.2
    At the Moss Point jail, approximately two hours after his
    arrest, Andrews was interrogated by agents of the Customs Service
    and DEA.    Andrews stated that he had leased the Concord from Aldo
    Gomez, whom he had met through Pedro Lopez, a Cuban from Miami.
    Other statements which Andrews made during the interview were used
    against him at trial, or were used by federal agents to obtain
    evidence about Andrews, the Concord, and its cargo.
    1
    One of the diagrams included the names of, or
    abbreviations for the names of, the countries Colombia, Peru,
    Argentina, Venezuela, and Panama. These names and abbreviations
    were connected to each other, and to the names of locations in
    Georgia and Florida, by a series of lines and arrows. At trial the
    government argued that the diagram depicted a marijuana
    distribution and importation network. See infra part II.C.2.
    2
    Federal agents observed Andrews driving erratically, as
    if he was attempting to evade surveillance. Andrews could have
    used the radio frequency detector to detect the agents' nearby
    radio transmissions while they were following him.
    -3-
    On the day after Andrews' arrest for DUI, fire fighters for
    the Pascagoula Fire Department searched inside the fuel tanks of
    the Concord and found a hidden, airtight compartment containing
    over four thousand pounds of marijuana, with an estimated street
    value of $3,600,000.       One of the firefighters testified that a
    diagram in Andrews' red spiral notebook depicted the Concord's fuel
    tanks and the location of the marijuana in the hidden compartment.
    An agent for the DEA interviewed Andrews again, and informed
    him that marijuana had been discovered on the Concord.             Andrews
    then stated that "Aldo Gomez was the key to everything in Panama,"
    and that the DEA could have "got" Gomez and "the big people" if
    they had waited until Gomez arrived in Pascagoula in a few days.
    Andrews was indicted for importing marijuana, in violation of
    21 U.S.C. §§ 952, 960, and possessing marijuana with intent to
    distribute, in violation of 21 U.S.C. § 841(a)(1).           Before trial,
    Andrews moved to suppress the notebook and radio frequency detector
    seized from his car, on the grounds that the search of his vehicle
    was an unreasonable search in violation of the Fourth Amendment.
    Andrews also moved to suppress statements he made to federal
    officers following his arrest for DUI, arguing that use of those
    statements   at   trial   would   violate   the   Fifth   Amendment.   The
    district court denied both motions to suppress. The jury convicted
    Andrews on both counts, and the district court sentenced him to 136
    months imprisonment.

    II
    A
    Andrews contends that the district court erred by admitting
    into evidence a notebook which was seized during a warrantless
    inventory search of Andrews' car after he was arrested for DUI.
    While conducting an inventory of the contents of Andrews' vehicle,
    MPPD Patrolman     Doug   Adams   opened     a    red   spiral   notebook,   and
    observed a diagram which he thought might be of evidentiary value
    to the DEA.3     Adams turned the notebook over to the DEA.             Before
    trial Andrews moved to suppress the notebook, and after conducting
    an evidentiary hearing, the district court denied the motion to
    suppress.     Andrews contends that Adams' search of the notebook and
    delivery of the notebook to the DEA violated his rights under the
    Fourth Amendment, because Adams exercised discretion which was not
    adequately     constrained   by   standard       MPPD   regulations   governing
    inventory searches.
    In reviewing the denial of a motion to suppress which alleges
    a violation of the Fourth Amendment, "we must accept the district
    court's purely factual findings unless they are clearly erroneous
    or influenced by an incorrect view of the law."              United States v.
    Hahn, 
    922 F.2d 243
    , 245 (5th Cir. 1991); see also United States v.
    Ramirez, 
    963 F.2d 693
    , 704-05 (5th Cir.), cert. denied, ___ U.S.
    3
    Adams' intuition was correct. Fire fighters from the
    Pascagoula Fire Department searched the tug boat Concord's fuel
    cells and discovered the marijuana storage compartment inside. One
    of the fire fighters testified that the diagram in Andrews'
    notebook depicted the fuel cells and the hidden storage
    compartment.

    113 S. Ct. 388
    , 
    121 L. Ed. 2d 296
    (1992).        However, "[t]he
    ultimate determination of reasonableness of the search . . . is a
    conclusion of law," which we review de novo.     
    Hahn, 922 F.2d at 245
    ; see also United States v. Capote-Capote,

    112 S. Ct. 2278
    , 
    119 L. Ed. 2d 204
    (1992).   We will not find a district court's factual
    determination to be clearly erroneous unless we are left with the
    definite and firm conviction that a mistake has been committed,
    United States v. Mitchell, 
    964 F.2d 454
    , 457-58 (5th Cir. 1992),
    and we view the evidence in the light most favorable to the party
    that prevailed below. See 
    Ramirez, 963 F.2d at 705
    ; 
    Capote-Capote, 946 F.2d at 1102
    .
    "The fourth amendment proscribes . . . unreasonable searches
    and seizures. To be reasonable a search must normally be conducted
    pursuant to a warrant, but courts have long recognized an exception
    to the warrant requirement for so-called ``inventory searches' of
    automobiles."   United States v. Prescott, 
    599 F.2d 103
    , 105 (5th
    Cir. 1979) (citations omitted); see South Dakota v. Opperman, 
    428 U.S. 364
    , 
    96 S. Ct. 3092
    , 
    49 L. Ed. 2d 1000
    (1976).    "When a car is
    impounded, the police generally inventory its contents to protect
    the owner's property while it is in police custody, to protect the
    police against claims of lost or stolen property, and to protect
    the police and the public from potential danger." United States v.
    Gallo, 
    927 F.2d 815
    , 819 (5th Cir. 1991) (citing 
    Opperman, 428 U.S. at 369
    , 96 S. Ct. at 3097).   Inventory searches are excepted from
    the warrant requirement because they serve these "caretaking"
    -6-
    purposes, and because they are not designed to uncover evidence of
    criminal activity.      See 
    Opperman, 428 U.S. at 370
    & 
    n.5, 96 S. Ct. at 3097
    & n.5 ("In view of the noncriminal context of inventory
    searches . . . courts have held))and quite correctly))that search
    warrants are not required. . . . With respect to noninvestigative
    police inventories of automobiles . . . the policies underlying the
    warrant requirement . . . are inapplicable.").
    Cases dealing with inventory searches have required that such
    searches   be   conducted        according     to   standard   regulations       and
    procedures,     consistent       with    the    proper   purpose     of    a    non-
    investigative inventory search.              In Opperman, the seminal case on
    the subject, the Supreme Court stated that "inventories pursuant to
    standard police procedures are reasonable," and noted that standard
    procedures are "a factor tending to ensure that the intrusion
    [represented by an inventory search] would be limited in scope to
    the extent necessary to carry out the caretaking function."

    .
    In Colorado v. Bertine, 
    479 U.S. 367
    , 
    107 S. Ct. 738
    , 93 L.
    Ed. 2d 739 (1987), after the defendant was stopped for driving
    under the influence of alcohol, an inventory of the contents of the
    defendant's vehicle revealed cocaine in a closed backpack. See 
    id. at 368-69,
    107 S. Ct. at 739.           The Court held that the search was
    not unreasonable,       stating       that   "reasonable   police    regulations
    relating to inventory procedures administered in good faith satisfy
    the Fourth Amendment."       
    Id. at 374,
    107 S. Ct. at 742.               The Court
    "emphasize[d]    that    .   .    .   the    Police   Department's    procedures
    -7-
    mandated the opening of closed containers and the listing of their
    contents."     
    Id. at 374
    n.6; 107 S. Ct. at 742 
    n.6.                 The defendant
    argued, nonetheless, that the inventory search was unconstitutional
    because    departmental     regulations        gave     the     police     officers
    discretion to decide whether to impound the defendant's vehicle.
    See 
    id. at 375,
    107 S. Ct. at 743.                    The Court rejected that
    argument because "[n]othing in Opperman or [Illinois v. Lafayette,
    
    462 U.S. 640
    , 
    103 S. Ct. 2605
    , 
    77 L. Ed. 2d 65
    (1983)] prohibits
    the exercise of police discretion so long as that discretion is
    exercised according to standard criteria and on the basis of
    something other than suspicion of evidence of criminal activity."
    
    Id. Most recently,
    in Florida v. Wells, 
    495 U.S. 1
    , 
    110 S. Ct. 1632
    , 
    109 L. Ed. 2d 1
    (1990), the Supreme Court held that Florida
    highway patrol officers violated the Fourth Amendment when, in the
    course of an inventory search of the defendant's vehicle, they
    opened a     locked   suitcase   and    discovered       a    large    quantity   of
    marijuana.     Id. at ___, 110 S. Ct. at 1634-35.                     "[T]he record
    contained no evidence of any Highway Patrol policy on the opening
    of closed containers found during inventory searches," and the
    Court   held   that   the   inventory        search    "was    not     sufficiently
    regulated to satisfy the Fourth Amendment."              Id. at ___, 110 S. Ct.
    at 1634-35.    The Court explained:
    Our view that standardized criteria must regulate the
    opening of containers found during inventory searches is
    based on the principle that an inventory search must not
    be a ruse for a general rummaging in order to discover
    incriminating evidence. The policy or practice governing
    inventory seaches should be designed to produce an
    -8-
    inventory. The individual police officer must not be
    allowed so much latitude that inventory searches are
    turned into "a purposeful and general means of
    discovering evidence of crime."
    Id. at ___, 110 S. Ct. at 1635 (citations omitted).
    Based    on   Patrolman   Adams'     testimony   at   the   suppression
    hearing, the district court found that Adams had searched the
    notebook according to "normal procedure . . . in Moss Point" and
    according to "a standardized routine."            That finding was not
    clearly erroneous.     Adams testified at the suppression hearing as
    follows:
    Q    [By the prosecutor] What was your purpose of doing
    the inventory search; why did you do it?
    A    Policy of Moss Point Police Department, when you
    arrest someone out of their vehicle, you tow it and do an
    inventory search of their personal belongings and items
    left in the vehicle for the protection of the city.
    Q       All right.    Is that standard operating procedures?
    A       Yes, ma'am.
    Q       Is it done in every case?
    A       Yes, ma'am.
    Q    And is it the policy, whether written or unwritten,
    of the police department to do that in every case?
    A       Yes, ma'am.
    Q       And obviously that includes traffic stops and DUIs?
    A       Yes, ma'am.
    Q    All right. And you said it was to protect the City
    of Moss Point or the police department, what do you mean
    by that?
    A    Well, so the person that's arrested doesn't come
    back and say, well, I had a five thousand dollar stereo,
    or five hundred dollars and now it's missing.
    -9-
    Record on Appeal, vol. 2, at 65-66.               Adams testified again at
    trial, regarding the MPPD's inventory policy:
    Q    [By defense counsel]    Do you have an inventory
    policy established at Moss Point Police Department?
    A    Yes, sir. Everybody that's arrested, that's driving
    a vehicle, you tow their vehicle, you do an inventory.
    Q    Is that a written policy or it's in written form?
    A    I can't say that I've seen a written policy but
    that's what I was instructed by my captain the day I went
    to work there.
    Q    So it doesn't have any ritual as far as how it's
    conducted. There's nothing written down, step by step
    procedure?
    A    No, sir, you just fill in the form.
    
    Id. vol. 3,
    at 214.       Adams' testimony, which was not contradicted,
    reveals that the Moss Point Police Department requires its officers
    to   conduct    inventory    searches,        including     the    completion   of
    inventory forms, for the purpose of protecting the city from claims
    of lost property.       The district court's finding is not clearly
    erroneous.
    Andrews contends, however, that a Fourth Amendment violation
    occurred because the "page-by-page search of [his] notebook was not
    mandated   or   allowed     by   any   policy    of   the   Moss    Point   Police
    Department."4    We disagree, because it appears that MPPD's policy
    did allow Adams to open Andrews' notebook, in order to determine
    whether it contained personal property which should have been
    included on an MPPD inventory form.                   Opening a notebook, to
    4
    Andrews does not contend that Adams' inventory search was merely a
    pretense for a search for evidence of criminal activity.
    -10-
    determine whether valuables might be found between its pages, is
    consistent with the MPPD policy requiring an inventory search to
    protect the city from claims of lost property. Cash, credit cards,
    negotiable instruments, and any number of other items could be
    hidden between the pages of a notebook, and could give rise to a
    claim against the city if lost.5
    Furthermore, MPPD's official procedures sufficiently regulate
    the discretion    of   its    officers   to    prevent     them   from   turning
    inventory   searches   into    "``a   purposeful      and   general      means   of
    discovering evidence of crime.'"            Wells, 495 U.S. at ___, 110 S.
    Ct. at 1635.   Adams testified that MPPD's policy requires officers
    to conduct an inventory in order to protect the city from claims
    for lost property.        This policy does not allow MPPD officers
    discretion to search a notebook in order to uncover evidence of
    criminal    wrongdoing.      An   officer     who   engages   in   "a    general
    rummaging in order to discover incriminating evidence," id. at ___,
    110 S. Ct. at 1635, exceeds his authority under the MPPD inventory
    search policy.

    See Record on Appeal, vol. 2, at 70 (Adams' testimony at
    suppression hearing) ("Q    [By the prosecutor]     Would you scan

    there might be something valuable stuck between the pages? A Yes,

    In Wells the majority observed that "it would be . . .
    permissible . . . to allow the opening of closed containers whose
    contents officers determine they are unable to ascertain from
    examining the containers' exteriors. The allowance of the exercise
    of judgment based on concerns related to the purposes of an
    inventory search does not violate the Fourth Amendment."              Id. at
    ___, 110 S. Ct. at 1635.        From Adams' testimony, it appears that
    the policy described by the Supreme Court in Wells is, for all
    intents and purposes, the policy of the MPPD.             MPPD officers are
    instructed (1) to conduct an inventory of an arrestee's vehicle,
    (2) to complete an inventory form, and (3) that the purpose of the
    inventory is to protect the city from claims of lost or stolen
    property.     An officer following these instructions must decide
    whether it is necessary to open a notebook in order to fulfill the
    function of an inventory search, but these discretionary decisions
    regarding the scope of the search will be made "based on concerns
    related to     the   purposes   of    an   inventory   search,"   unless   the
    searching officer oversteps the bounds of her authority under the
    MPPD policy.
    In Wells, the Court pointed out that there was "no evidence of
    any Highway Patrol policy on the opening of closed containers found
    during inventory searches."          Id. at ___, 110 S. Ct. at 1635.       In
    Bertine the Court "emphasize[d] that . . . the Police Department's
    procedures mandated the opening of closed containers and the
    listing of their contents."          
    Id., 479 U.S.
    at 374 
    n.6; 107 S. Ct. at 742
    n.6.     However, neither of those decisions requires a law
    -12-
    enforcement agency's inventory policy to address specifically the
    steps that an officer should take upon encountering a closed
    container.         Neither do we understand those cases to require the
    Moss       Point   Police   Department     to   promulgate    policies    which
    specifically mention notebooks.6           The requirement to be distilled
    from the line of cases culminating in Wells is that inventory
    policies must be adopted which sufficiently limit the discretion of
    law       enforcement   officers   to   prevent   inventory    searches   from
    becoming evidentiary searches.            See United States v. Judge, 
    864 F.2d 1144
    , 1145 (5th Cir. 1989) (stating that Bertine "does not
    condemn all forms of police discretion, but only ``evidentiary'

    as   department    policy          permitted      opening     box    for    the    standard
    purposes of inventory searches).
    Andrews also argues, however, that no standardized policy
    permitted Adams to turn the notebook over to the DEA and the United
    States Customs Service.                 Andrews contends that when Adams turned
    the notebook      over       to    federal     officials,         "[w]hat    began    as    an
    inventory      search    .    .     .    became     an    excuse    for    ``investigatory
    rummaging' on behalf of Customs and DEA."                          Andrews' argument is
    without   merit.         "Once       property       has    been    seized    with    proper
    justification and is in plain view of governmental officials, the
    owner no longer has a reasonable expectation of privacy with
    respect to that property, and it may be seized without a warrant."

      (1988).      When       Adams       turned   the     notebook    over    to     federal
    officials and they reviewed it, it had already been seized with
    proper justification, pursuant to a valid inventory search.
    United States v. Khoury, 
    901 F.2d 948
    (11th Cir. 1990), upon
    which Andrews relies, is distinguishable.                      In Khoury a DEA agent
    examined the defendant's notebook in the course of an inventory
    search, but did not discover that the notebook had evidentiary
    value.    
    Id. at 959.
                The purposes of the inventory search being
    fulfilled, the inventory exception to the warrant requirement was
    no longer available; but the agent examined the notebook again,
    this time determining that it had evidentiary value.                               
    Id. The Eleventh
    Circuit held that the agent's second look at the notebook,
    -14-
    without a warrant, violated the Fourth Amendment.                 
    Id. In the
    course of his inventory search of Andrews' car, Adams determined
    that the diagram and various names in the notebook had evidentiary
    value pertinent to the federal agents' investigation.               Khoury is
    distinguishable,      therefore,    because      Adams   was    aware    of   the
    evidentiary value of the notebook before a second look was taken by
    federal agents.    See 
    Thompson, 837 F.2d at 675
    (noting that no
    exception to the warrant requirement is available where a "second
    inspection [of evidence in government custody is] undertaken to
    look for something that had not been discovered at the time of the
    inventory" (distinguishing Brett v. United States, 
    412 F.2d 401
    ,
    405 (5th Cir. 1969)). Andrews has not demonstrated that his rights
    under the Fourth Amendment were violated, or that the district
    court erred by denying his motion to suppress.
    B
    Andrews next contends that the district court erred by denying
    his motion to suppress statements which he made to law enforcement
    officers after being arrested for driving under the influence of
    alcohol.    Andrews     contends     that   he    did    not    knowingly     and
    intelligently waive his rights under Miranda v. Arizona, because he
    was too drunk to understand those rights and the consequences of
    relinquishing them.
    1
    Under Miranda, statements made by a defendant during custodial
    interrogation   may    not   be    used   against    him   at    trial   unless
    procedural safeguards are employed to protect the defendant's Fifth
    -15-
    Amendment privilege against self-incrimination.            See 
    id., 384 U.S.
    at 
    478-79, 86 S. Ct. at 1630
    .         This requirement is most commonly
    satisfied by giving the defendant the customary Miranda warnings:
    that he has the right to remain silent, that anything he says can
    be used against him in a court of law, that he has the right to the
    presence of an attorney, and that an attorney will be provided for
    him if he cannot afford to hire one.         See 
    id., 384 U.S.
    at 
    479, 86 S. Ct. at 1630
    .     "After such warnings have been given, and such
    opportunity    afforded      him,   the   individual    may   knowingly   and
    intelligently waive these rights and agree to answer questions or
    make a statement."     
    Id. The defendant
    "``may waive effectuation' of the rights conveyed
    in the warnings ``provided the waiver is made voluntarily, knowingly
    and intelligently.'"      Moran v. Burbine, 
    475 U.S. 412
    , 421, 106 S.
    Ct. 1135, 1140-41, 
    89 L. Ed. 2d 410
    (1986) (quoting 
    Miranda, 384 U.S. at 444
    , 
    475, 86 S. Ct. at 1612
    , 1628).            The inquiry whether a
    valid waiver has occurred "has two distinct dimensions. First, the
    relinquishment of the right must have been voluntary in the sense
    that it was the product of a free and deliberate choice rather than
    intimidation, coercion, or deception. Second, the waiver must have
    been made with a full awareness of both the nature of the right
    being abandoned and the consequences of the decision to abandon
    it."   
    Id. at 421,
    106 S. Ct. at 1141.        When the prosecution offers
    statements made by a defendant during custodial interrogation, "a
    heavy burden rests on the government to demonstrate that the
    defendant knowingly and intelligently waived his privilege against
    -16-
    self-incrimination and his right to retained or appointed counsel."

    Initially, Andrews contends that the district court "erred in
    deciding only the voluntariness of [his] Miranda waiver, without
    determining whether [it] was knowing and intelligent."                  Andrews
    argues that the district court should have made an express finding
    as to the knowing and intelligent nature of his Miranda waiver.7
    Plainly a defendant's motion to suppress should not be denied
    on the basis of a Miranda waiver, absent a finding by the district
    court that the waiver was knowing and intelligent.8               However, such
    a finding may be inferred by an appellate court, given adequate
    support in the record.            Several other circuits have inferred that
    the district court made factual findings reflecting a valid waiver,
    even though such findings were not expressly stated in the record.
    See United States v. Whitworth, 
    856 F.2d 1268
    , 1278 (9th Cir. 1988)
    (holding that waiver of Miranda rights was valid where "``finding

    564 F.2d 813
    (8th Cir.
    1977), the district court found "with unmistakable clarity" that
    the defendant had made a knowing and intelligent waiver, by stating
    that the defendant "knew what was going on" and "handled the

    ,
    
    92 S. Ct. 696

    (1972), the district court
    expressly credited a police officer's testimony "that he did
    properly advise [the defendant] of his right to remain silent [and]
    his right to counsel, and [the defendant] responded that he knew
    his rights."       
    Id. at 79.
          The Eighth Circuit found that the
    district court had made "a legal finding of ``unmistakable clarity'"
    on the facts predicate to a valid Miranda waiver.              See 
    id. (quoting Evans).
       In Gardner the Seventh Circuit held that the district
    court's findings reflected the facts with unmistakable clarity
    where the district court simply stated, "The motion to suppress is
    overruled."      See 
    Gardner, 516 F.2d at 340
    .           The court explained:
    "[W]e are not limited to looking only at the district court's one
    sentence   conclusion,    and   .   .   .   we   think   the   record   clearly
    discloses that the court was aware of the Miranda requirement [of
    a knowing waiver] and that the court's ruling was the result of its
    application."      
    Id. The Seventh
    Circuit relied on the fact that
    counsel's arguments "put the issue of whether [the defendant]
    knowingly waived his right to remain silent squarely before the
    court."    
    Id. -19- "While
    it would have been preferable for the trial judge to
    have specifically stated whether or not there was a knowing and
    intelligent waiver of rights by the defendant," 
    Chapman, 448 F.2d at 1387
    n.8, guided by the foregoing decisions we conclude that the
    district court's finding of a knowing and intelligent waiver is
    sufficiently reflected in the record to obviate a remand for
    further factual determination.       At the suppression hearing, DEA
    Special Agent Karl Winter described his interrogation of Andrews
    approximately two hours after Andrews was arrested for DUI. Winter
    testified that he read Andrews the Miranda warnings, and that
    Andrews indicated that he understood them.          Winter also responded
    affirmatively    when   the   prosecutor   asked    whether     Andrews   had
    appeared to be "able to reason and understand what [they] were
    discussing."      In overruling Andrews' motion to suppress, the
    district court stated, "I think as far as the statements were
    concerned, I accept the testimony of the officers.              I think that
    [Andrews] was given his Miranda warnings.          I think he freely gave
    whatever statements . . . were given.            I think those statements
    were taken in appropriate fashion and the motion will be overruled
    as to the statements."        The district court apparently credited
    Winter's statement that Andrews said he understood the Miranda
    rights which were read to him.       The record therefore reflects a
    finding   by    the   district   court    that    Andrews     knowingly   and
    intelligently waived his rights under Miranda.              See 
    Shabazz, 446 F.2d at 79
    (where district court's statement crediting officer's
    testimony amounted to a "legal finding of ``unmistakable clarity'").

    The cases cited by Andrews on this issue, Edwards v. Arizona,
    
    451 U.S. 477
    , 
    101 S. Ct. 1880
    , 
    68 L. Ed. 2d 378
    (1981), and United
    States    v.   Bradshaw,   
    935 F.2d 295
      (D.C.   Cir.   1991),   are
    distinguishable.    In Edwards, the Supreme Court held that "neither
    the trial court nor the Arizona Supreme Court undertook to focus on
    whether Edwards understood his right to counsel and intelligently
    and knowingly relinquished it."          See 
    id., 451 U.S.
    at 
    483-84, 101 S. Ct. at 1884
    .     However, that conclusion was supported by the
    Arizona Supreme Court's reliance on Schneckloth v. Bustamonte,10 in
    which the Court "declined to impose the ``intentional relinquishment
    or abandonment of a known right or privilege' standard and required
    only that . . . consent [to search] be voluntary . . . ."              
    Id. at 483,
    101 S. Ct. at 1884.         Similarly in Bradshaw, where the D.C.
    Circuit held that the district court "made no finding with respect
    to Bradshaw's understanding of his rights," the record revealed
    that the district court "considered only whether Bradshaw's waiver
    was voluntary . . . ."     
    Id., 935 F.2d
    at 298, 300.11         Because the
    record does not contain similar affirmative indications that the
    district court failed to decide whether Andrews made a knowing and
    intelligent     Miranda    waiver,        Edwards    and    Bradshaw     are
    distinguishable.     The record adequately reflects the district
    court's finding that Andrews' waiver was knowing and voluntary.

    Andrews contends, however, that his waiver was not knowing and
    intelligent, because he was still drunk when he spoke to federal
    agents following his arrest for DUI, and therefore the district
    court erred by denying his motion to suppress.           When reviewing a
    district court's denial of a motion to suppress, premised on an
    alleged violation    of   Miranda,   we   "must   give   credence   to   the
    credibility choices and findings of fact of the district court
    unless clearly erroneous."    United States v. Raymer, 
    876 F.2d 383

    , 
    110 S. Ct. 198
    , 107 L.
    Ed. 2d 152 (1989).    The determination that a defendant's Miranda
    waiver was knowing and intelligent is a finding of fact which we
    review for clear error.12    See United States v. Willis, 
    525 F.2d 657
    , 659 (5th Cir. 1976) (holding that district court's findings
    "were not clearly erroneous" where "[t]here was . . . sufficient
    evidence . . . that the defendant's waiver of his rights was
    knowing and intelligent").     We will not find a district court's
    factual determination to be clearly erroneous unless we are left
    with the definite and firm conviction that a mistake has been
    committed.

    Andrews emphasizes that approximately two hours before the
    interrogation he was arrested for DUI and failed several roadside
    sobriety tests.   According to Patrolman Adams' testimony, Andrews
    was unable to walk a straight line, and he "stumbled through"
    12
    "The ultimate issue of voluntariness is a legal issue,
    however, which requires the appellate court to make an independent
    determination."

    reciting the alphabet from the letter "O" and counting backwards
    from 25 to 10.    Andrews also failed a portable breathalyzer test,
    and Adams testified that at the time of his arrest Andrews smelled
    of alcohol and exhibited slurred speech. Andrews testified that at
    the time of the interrogation he "was . . . rudely awakened by the
    jailer . . . had drank that day and . . . had not slept good the
    night before."    Andrews testified, "I was, basically, I was not in
    that good of shape."    When asked whether he was "still feeling the
    effects     of   alcohol"    when    interrogated,    Andrews   responded
    affirmatively:    "By reading the statements that they say I'd made,
    most definitely, I would.           I would not have made some of the
    statements if I had not been feeling under the effects still."
    Andrews further testified, "If I had been totally straight, I would
    not have said a word to [the federal agents]. . . . . If I had not
    been drinking, I would not have spoken to them without a lawyer
    present."
    The evidence of Andrews' intoxication pertains primarily to
    the time of his arrest, roughly two hours before he waived his
    Miranda rights, except for his testimony that he would not have
    spoken to the agents if he hadn't been drunk.        The latter testimony
    tends to show that he was too intoxicated at the time of the
    interrogation to understand his Miranda rights.        However, Andrews'
    testimony was contradicted by the testimony of two agents who
    interrogated Andrews.       Special Agent Raymond Parmer, of the United
    States Customs Service, testified that he and other interrogating
    agents "tried to make sure [Andrews] had enough time [to] recover
    -23-
    from his inebriation before [they] interviewed him in any way."
    Parmer further testified that at the time of the interrogation
    Andrews did not appear inebriated.            DEA Special Agent Karl Winter
    testified that at the time of the interrogation it "appeared that
    [Andrews] had been drinking, but . . . he seemed pretty reasonable"
    and "aware of his surroundings and everything . . . ."                 Winter
    also responded affirmatively when the prosecutor asked whether
    Andrews appeared to be "able to reason and understand what [they]
    were discussing."    Finally, Winter testified that he read Andrews
    the Miranda warnings, and that Andrews indicated he understood
    them.
    The district court was in the best position to judge the
    weight   and   credibility   of   the       conflicting   evidence   regarding
    Andrews' condition, and could have concluded that Andrews was not
    so drunk when interrogated that he did not understand his rights
    and the consequences of relinquishing them.                As a result, the
    district court's finding that Andrews knowingly and intelligently
    waived his rights under Miranda was not clearly erroneous, and
    Andrews has not demonstrated that the district court erred by
    denying his motion to suppress.
    C
    Andrews further contends that he is entitled to reversal
    because of the prosecutor's improper comments at trial.              "Improper
    comments by a prosecutor may constitute reversible error where the
    defendant's right to a fair trial is substantially affected."

    magnitude of the prejudicial effect of the statements; (2) the
    efficacy of any cautionary instruction; and (3) the strength of the
    evidence of the defendant's guilt."

    conviction is
    not to be lightly overturned on the basis of a prosecutor's

    Because Andrews     failed     to   object     to   any    of    the   prosecutor's
    comments, however, he bears an even greater burden:                        we will
    reverse only if the prosecutor's conduct amounts to plain error.

    Andrews     first   argues   that     the    prosecutor     argued   facts
    unsupported by the evidence during closing argument, when she
    questioned the profitability of Andrews' tug boat operation.                At
    trial the prosecutor asked Andrews, "The daily rent . . . under the
    lease for that tugboat was eight hundred dollars a day; isn't that
    correct, Mr. Andrews?" Andrews answered that that was correct. In
    closing, the prosecutor argued:
    They thought they were being smart, they thought they
    were being sneaky[,] and they thought they could fool the
    Government by having a sham front business. We'll have
    a lease that says we're going to pay eight hundred
    dollars a day rent. Now, if you believe that, I mean,
    really. What kind of profit are you going to make with
    expenses like that[?]
    Record on Appeal, vol. 4, at 531.                Andrews contends that the
    prosecutor's argument was improper, because there was no evidence
    in the record that a tug boat service would not be profitable with
    rental expenses of $800 per day.          See United States v. Morris, 
    568 F.2d 396
    , 401 (5th Cir. 1978) (stating that prosecutor generally
    may not "inject into his argument any extrinsic or prejudicial
    matter that has no basis in the evidence").
    Assuming arguendo that the prosecutor's remarks were improper,
    reversal is inappropriate because Andrews has not demonstrated
    plain   error.     Andrews   baldly       asserts   that   the   prosecutor's
    misconduct was so obvious that our failure to notice it would
    seriously affect the fairness, integrity, or public reputation of
    judicial proceedings and result in a miscarriage of justice.
    However, aside from asserting that "there is very little evidence
    -26-
    of the defendant's guilty knowledge" in this case, Andrews fails to
    present an argument, based on the record or the law, which would
    justify a conclusion that the prosecutor's comment "cast[s] serious
    doubt on the correctness of the jury's verdict," 
    Iredia, 866 F.2d at 117
    , or that this is an "exceptional" case which merits a
    finding of plain error.   
    Wicker, 933 F.2d at 291
    .13   It is not our
    place to make such arguments on Andrews' behalf.   As he has failed
    to do so, he is not entitled to reversal.
    2
    Andrews also contends that the evidence did not support the
    prosecutor's inference that the diagram in Andrews' red notebook
    depicted a drug importation network.     In the diagram, the word
    "Peru" and the abbreviations "Col", "Ven", and "Arg." appear above
    the word "Panama".   Four lines connect "Panama" to the word and
    three abbreviations appearing above it, more or less in the fashion
    of spokes in a wagon wheel.   The words and abbreviations "Central
    Fla", "West Fla.", and "Ga. to Gina", as well as the names of
    several roads in southern Florida, appear below the word "Panama",
    and are connected to "Panama" by a vertical line and descending
    13
    We have reviewed the decisions cited by Andrews, and none
    of them supports the proposition that the prosecutor committed
    plain error.   Wicker))which Andrews cites specifically for that
    proposition))is to the contrary. In Wicker the prosecutor did not
    commit plain error by saying, "What real estate broker have you
    ever heard of that pays $25,905 for his clients in a real estate
    transaction? I don't know of anybody that would do that . . . ."
    
    Id., 933 F.2d
    at 291-92.      We explained that the prosecutor's
    "comments were primarily rhetorical," and that "[n]one could fairly
    be understood to express a personal belief by the prosecutor in
    Wicker's guilt." 
    Id. at 292.

    arrows. Andrews testified that his daughter Gina lived in Georgia.
    The prosecutor argued at closing:
    [Andrews] had a diagram in his notebook that was in his
    car listing four major source countries of drugs, Peru,
    Colombia, Venezuela, Argentina and they're all converging
    on Panama where his dope boat is located. They could
    take the marijuana, whatever, from these countries put it
    on the boat in Panama and take it to the United States,
    central Florida, west Florida.         This is a drug
    distribution network. That's plain and simply, all it
    is.
    Record on Appeal, vol. 4, at 512.14          Andrews contends that no
    evidence supported the prosecutor's inference that the diagram
    depicted a drug distribution network, and that this "was an unfair
    inference that was highly prejudicial to the defendant."               We
    disagree.
    Although   the   evidence   did   not   support   the   prosecutor's
    statement that Venezuela and Argentina are major sources of illegal
    drugs imported into the United States,15 Andrews admitted at trial
    that Colombia and Peru are source countries.      Because the evidence
    supports the conclusion that Colombia and Peru are sources of
    illegal drugs, it is reasonable to infer that Andrews' diagram
    depicted the importation of drugs into the United States from those
    countries via Panama.   The prosecutor's ultimate conclusions))that

    The prosecutor also argued, "Jimmy is the man in Colombia
    with the drugs, just like in the little drawing, the Colombia,
    Peru, Venezuela."
    15
    Andrews testified that he didn't think either Venezuela
    or Argentina was a source of illegal drugs, but he testified that
    he would not disagree with a DEA agent if the agent said Argentina
    was a source. The government does not contend that any evidence
    established that Argentina and Venezuela are major source
    countries.
    -28-
    the diagram depicted the importation of drugs into the United
    States, and Andrews therefore was aware of a scheme to import
    marijuana))were reasonable inferences from the evidence.                Andrews
    fails to show plain error.       See United States v. Morris, 
    568 F.2d 396
    , 401 (5th Cir. 1978) ("The purpose of summations is for the
    attorneys to assist the jury in analyzing, evaluating and applying
    the evidence. . . . The assistance permitted includes counsel's
    right to state his contention as to the conclusions that the jury
    should draw from the evidence." (emphasis omitted)).
    3
    Andrews      further   argues    that   the    prosecutor     engaged      in
    misconduct   by    inferring   that    Andrews     docked   the   tug   boat    in
    Pascagoula, rather than a larger port such as New Orleans or Miami,
    in order to avoid detection by the United States Customs Service.
    On cross-examination Andrews explained that he chose the Pascagoula
    port because it was cheaper.          However, in closing the prosecutor
    argued that Andrews chose Pascagoula because it had "the lowest
    level of law enforcement," whereas Miami and New Orleans had "a lot
    of Customs enforcement."       Andrews contends that the prosecutor's
    argument was not supported by the evidence.                 We disagree.       The
    evidence showed that the boatyard where the Concord docked at
    Pascagoula is small, isolated, and secluded, and is not a busy
    docking area.     The prosecutor reasonably inferred from those facts
    that docking the Concord at Pascagoula exposed Andrews to less risk
    of detection by law enforcement, and that was a factor in Andrews'
    -29-
    decision to dock the tug boat there.        Andrews has not demonstrated
    plain error.16
    4
    Andrews     also   contends     that   the   prosecutor   engaged   in
    misconduct by expressing her personal opinion of his credibility.
    See 
    Anchondo-Sandoval, 910 F.2d at 1238
    (stating that "it is
    improper and highly inappropriate [for the prosecutor] to interject
    his or her personal opinion of the defendant's veracity into the
    decision-making process").         The record does not support Andrews'
    argument.
    It is undisputed that Andrews intended to have the fuel tanks
    of the Concord drained in Pascagoula.         Andrews testified that the
    fuel had become contaminated:
    Q    [by defense counsel] And did you have any knowledge
    of any fuel problems . . . ?
    A    When)) the first crew stated to me, when they pulled
    the fuel out, there was a tanker sitting next to it and
    it was raining cats and dogs. Down south there, it rains
    about like it does here and that)) the fuel was
    contaminated.
    Record on Appeal, vol. 3, at 374.           In her closing argument, the
    prosecutor contended that Andrews "made up" a story "that the fuel
    tanks were going to be cleaned because it had been raining."
    16
    With respect to all of the foregoing claims of
    prosecutorial misconduct, we note that the district court gave the
    following jury instruction:      "Remember that any statements,
    objections, or arguments made by the lawyers are not evidence.
    . . . In the final analysis . . . it is your own recollection and
    interpretation of the evidence that controls in the case. What the
    lawyers say is not binding on it." In Morris, we held that an
    improper statement by the prosecutor was harmless, in light of the
    district court's instruction that "the attorneys' statements are
    not evidence to be considered by the jury." 
    Id., 568 F.2d
    at 402.
    -30-
    Referring to photographic exhibits which depicted the fuel tanks of
    the Concord, the prosecutor argued that it was impossible for the
    fuel to be contaminated by rain because the manhole covers to the
    fuel tanks were located indoors, and thus could not be reached by
    rain.    She argued that Andrews concocted the contamination-by-rain
    scenario because he intended to drain the fuel tanks and unload the
    marijuana hidden inside.
    Andrews contends that (1) the prosecutor mischaracterized his
    testimony, because he "never testified that rain entered the fuel
    cells    through   the    manhole   covers;"   and   (2)   the   prosecutor's
    statement that Andrews "made up" the story about contamination by
    rain was therefore nothing more than the prosecutor's unfounded
    personal opinion of his credibility.             We disagree.        Andrews'
    testimony can reasonably be construed as a statement that rain
    entered the fuel tanks of the Concord, and absent evidence of some
    means of entry other than the manhole covers,17 it was reasonable
    for the prosecutor to construe Andrews' testimony as a statement
    that the rain entered the fuel tanks through the manhole covers.
    The prosecutor did not err by arguing to the jury, based on the
    evidence, that Andrews testified to an impossibility.             Andrews has
    not demonstrated plain error.
    5
    Andrews       also   contends    that     the   prosecutor     made   an
    impermissible "conscience of the community" argument, inciting the
    17
    Andrews does not argue that the record contains any such
    evidence.
    -31-
    emotions   and   prejudices    of   the       jury   by   emphasizing     Andrews'
    decision   to    import   drugs   at    Pascagoula        despite   his   lack   of
    connections to that community.          This argument is without merit.
    On cross-examination the prosecutor elicited information from
    Andrews which demonstrated his lack of personal connections to
    Pascagoula and to Mississippi:         the fact that he had never lived in
    Mississippi, had neither family nor long-time friends there, and
    did not know the postal abbreviation for the name of the state.                   In
    her summation the prosecutor stated that Andrews "is the man in
    Miami with the crew to transport the dope and he picks out what he
    thought was and what he hoped was an unsophisticated town on the
    Mississippi Gulf Coast, Pascagoula, to sneak this marijuana into."
    The prosecutor further argued that Andrews "planned from the very
    beginning to use our harbors, our ports in this state to sneak in
    two tons of marijuana.       He didn't want to go to Miami, he didn't
    want to go to New Orleans.          He might have gotten caught.             So he
    decides to use Mississippi, to use our ports, our boat yards to
    bring in his drugs."
    Although     the     prosecutor      emphasized        Andrews'      lack    of
    connections to Pascagoula, the record reveals that she did so to
    show why Andrews docked the Concord there, and not to incite the
    prejudices of the jury.       The prosecutor argued that Andrews went
    out of his way to dock the Concord at a small, inconspicuous
    boatyard, where a shipment of marijuana might not be detected by
    the United States Customs Service.              
    See supra
    , part II.C.3.          The
    portion of the prosecutor's argument quoted in Andrews' brief
    -32-
    reveals that the prosecutor's purpose was to show why Andrews chose
    Pascagoula:     "He didn't want to go to Miami, he didn't want to go
    to New Orleans.      He might have gotten caught.         So he decides to use
    Mississippi, to use our ports, our boat yards to bring in his
    drugs." The record does not support Andrews' claim that "an ``Us v.
    Them' relationship between the jurors and the defendant" was
    created, even inadvertently, by the prosecutor's argument.                  Plain
    error is not shown.
    6
    Lastly,   Andrews    contends      that   the     prosecutor      improperly
    commented on Andrews' failure to call a number of witnesses in his
    own behalf.18    See 
    Iredia, 866 F.2d at 118
    ("The well-settled rule
    is that drawing any inferences from a party's failure to call a
    witness    equally   available    to    both    sides    is    impermissible.").
    Andrews contends that the prosecutor "effectively shifted the
    burden of proof in this prosecution to the defendant."                    Assuming
    arguendo that the prosecutor's remarks were improper, Andrews'
    argument that the burden of proof was shifted is not supported by
    the   record,    because   the    district      court    gave     the   following
    instructions to the jury:        "[T]he defendant is presumed by the law
    to be innocent.      The law does not require a defendant to prove his
    innocence or to produce any evidence at all.                  The government has
    the burden of proving the defendant guilty beyond a reasonable
    doubt, and if it fails to do so, you must acquit the defendant."
    18
    The prosecutor referred to five potential witnesses:
    Andrews' mother, Lopez, Gomez, the captain of the first crew of the
    Concord, and Luis, a Costa Rican crew member.
    -33-
    See   
    Iredia, 866 F.2d at 117
    -18         (holding      that      prosecutor's
    comment))"if there was . . . evidence available to defense lawyers
    don't you think they would put it on"))did not require reversal,
    because    district      court's      instruction))that           burden       was   on   the
    government))"should have sufficiently erased any doubts as to which
    party had the burden of proof").                Plain error is not shown.19
    D
    Andrews    contends       that    the       district        court's      instruction
    regarding the elements of importation of marijuana was inadequate
    because    it   failed    to    require      the      jury   to    find       that   Andrews
    knowingly brought marijuana into the United States.                           The district
    court instructed the jury :
    Title 21, United States Code, Sections 952(a) and
    960(a)(1), make it a crime for anyone knowingly or
    intentionally to import a controlled substance.
    *    *     *
    For you to find the defendant guilty of this crime,
    you must be convinced that the government has proved each
    of the following beyond a reasonable doubt:
    First: That the defendant brought a quantity
    of marijuana into the United States from a place outside
    the United States; and,
    Second: That the defendant knew the substance
    he was bringing into the United States was a controlled
    substance.
    Record on Appeal, vol. 4, at 548-49.                          Andrews asked for an
    instruction that, in order to find him guilty, the jury must find
    "First:     That   the     defendant       knowingly         brought      a    quantity    of
    marijuana into the United States . . . ."                          The district court

    Neither do we conclude that the prosecutor's actions,
    although not individually requiring reversal, by their cumulative
    effect add up to plain error.
    -34-
    denied the request, and Andrews contends that the jury therefore
    could have convicted him of importation without finding that he
    knew the marijuana was on the Concord.
    "[C]ourts      are        given    wide       latitude    in    framing     jury

    113 S. Ct. 1291
    , 
    122 L. Ed. 2d
    683 (1993).      We will reverse the district court's refusal to
    submit a requested jury instruction if, but only if the requested
    instruction   "(1)        is     substantially         correct;     (2)   was     not
    substantially covered in the charge actually delivered to the jury;
    and (3) concerns an important point in the trial so that the
    failure to give it seriously impaired the defendant's ability to
    present a given defense."          
    Id. (quoting United
    States v. Chambers,
    
    922 F.2d 228
    , 241 (5th Cir. 1991)).
    The district court did not commit reversible error, because
    Andrews' requested instruction was substantially covered by the
    charge   actually    delivered         to    the   jury.      The   district    court
    instructed the jury not to convict Andrews unless he "knew the
    substance he was bringing into the United States was a controlled
    substance."   The jury could not have found that Andrews knew a
    substance he was bringing into the United States was a controlled
    substance, without finding that Andrews knew he was bringing a
    substance into the United States.                  The district court's charge
    plainly did not permit the jury to convict Andrews without first
    determining that he knew the marijuana was on board the tug boat.

    Andrews contends that his trial counsel failed to call expert
    witnesses who could have testified regarding (1) the legitimate
    uses for a radio frequency detector such as the one found in
    Andrews' car; and (2) the lack of correlation between the sketch
    found in Andrews' notebook and the Concord's fuel cells.                 Andrews
    also contends that counsel was ineffective for failing to object to
    the prosecutor's improper closing argument, which now results in
    review under the plain error standard.20
    Andrews moved in the district court for dismissal of his trial
    counsel, on the grounds that counsel was ineffective under the
    standards announced in Strickland.           However, the specific claims
    now raised on appeal were not presented to the district court.
    Andrews' pro se motion presented general allegations that counsel
    failed to subpoena witnesses requested by Andrews, and the district
    court denied the motion without a hearing, stating that Andrews had

    "not provided sufficient evidence that his court-appointed counsel
    [was] ineffective."
    Because Andrews' claim of ineffective assistance was not
    presented below with sufficient specificity to allow the district
    court "to develop the record on the merits of the allegations," "we
    can only speculate on the basis for defense counsel's actions."
    
    Higdon, 832 F.2d at 314
    .    We therefore "decline to address the
    merits of [Andrews'] ineffective assistance claim, but we do so
    without prejudice to [his] right to raise the issue in a proper
    proceeding pursuant to 28 U.S.C. § 2255."    Id.21

    For the foregoing reasons, we AFFIRM.

    Lastly Andrews contends, in the alternative, that even if
    none of the foregoing alleged errors warrants reversal, the
    cumulative effect of all of the errors requires a new trial. In
    support of that assertion, Andrews merely quotes our decision in
    United States v. Canales, 
    744 F.2d 413
    (5th Cir. 1984), for the
    rule that "the cumulative effect of several incidents of improper
    argument or misconduct may require reversal, even though no single
    one of the incidents, considered alone, would warrant such a
    result."   
    Id. at 430.
        We are not persuaded that Andrews is
    entitled to reversal on the basis of cumulative error. See United
    States v. Moye, 
    951 F.2d 59
    , 63 n.7 (5th Cir. 1992) ("Because we
    find no merit to any of Moye's arguments of error, his claim of
    cumulative error must also fail."); cf. Derden v. McNeel, 
    978 F.2d 1453
    , 1458 (5th Cir. 1992) (en banc) (holding that claim of
    cumulative error does not entitle state prisoner to habeas corpus
    relief unless (1) claim of cumulative error refers to errors,
    rather than mere unfavorable rulings or events; (2) habeas review
    is not procedurally barred; and (3) the errors more likely than not
    caused a suspect verdict), cert. denied, ___ U.S. ___, 
    113 S. Ct. 2928
    , 
    124 L. Ed. 2d 679
    (1993).
