Defendants-appellants Terry Greenberg (“Greenberg”), Hector Favio Marin-Hernandez (“Marin-Hernandez”) and Leonardo Mendoza-Cecelia (“Mendoza-Cecelia”) appeal their convictions on charges arising from trafficking in marijuana. Greenberg also appeals his sentence. For the reasons which follow, we affirm appellants’ convictions and Greenberg’s sentence.
I. STATEMENT OF THE CASE
On November 19, 1988, Greenberg, Marin-Hernandez, Mendoza-Cecelia and three others left Santa Maria, Colombia, aboard the Apache III, a 37-foot fishing vessel of United States registry. The vessel was laden with approximately 6,500 pounds of marijuana and was destined for Key West, Florida. After extensive surveillance, a detachment of United States Coast Guard officers aboard a United States Navy vessel detained the crew of Apache III within several miles of the Grand Cayman Islands. The Coast Guard quickly discovered the marijuana and arrested the crew. The crew was held on the Navy vessel and questioned the following day. Greenberg subsequently made incriminating statements on separate occasions to a Coast Guard officer, to a Customs official and to a magistrate judge.
On December 6, 1988, the six crew members were indicted for possession with intent to distribute marijuana, in violation of 46 U.S.C.A. §§ 1903(a) and (g) (West Supp. 1992) and 18 U.S.C.A. § 2 (West 1969) (Count I), and for conspiracy to distribute marijuana, in violation of 46 U.S.C.A. §§ 1903(j) and (g) (West Supp.1992) (Count II). On June 29, 1990, a jury convicted Greenberg and Mendoza-Cecelia on both counts of the indictment and Marin-Hernandez on Count II only. 1 Greenberg re *1471 ceived two concurrent sentences of 365 months imprisonment and a five-year term of supervised release; Mendoza-Cecelia received two concurrent sentences of 121 months imprisonment and a five-year term of supervised release; Marin-Hernandez was sentenced to a 210-month term of imprisonment and a five-year term of supervised release.
II. ANALYSIS
Appellants raise the following claims on appeal: (1) the government denied Green-berg his right to counsel as guaranteed by the Sixth Amendment and as recognized under the Fifth Amendment in
Miranda v. Arizona,
A. Motion to Suppress
Greenberg made incriminating statements during interrogation by law enforcement personnel and in his initial appearance before a magistrate judge. He argues that his two inculpatory statements to law officers were made subsequent to his equivocal invocation of his Fifth Amendment right to counsel and therefore were obtained in violation of the
Miranda-Edwards
doctrine.
See id., Edwards v. Arizona,
1. Statements to Interrogating Officers
The Coast Guard apprised Greenberg of his Miranda rights upon arresting him on the Apache III. Greenberg was then brought to the Navy vessel U.S.S. Stump. The next day, Coast Guard officers read Greenberg his Miranda rights before removing him to another part of the vessel for interrogation. At the beginning of this session, Greenberg stated, “I don’t know if I need a lawyer—maybe I should have one, but I don’t know if it would do me any good at this point.” The interrogating officers continued their questioning without responding to Greenberg’s statement. Greenberg subsequently agreed to make both a written and videotaped confession. Later in the United States, Greenberg made an incriminating statement during interrogation by Customs Agent Robert Abramson.
The district court found that Greenberg’s comment during the first interrogation session was ambiguous enough not “to cause law enforcement officers to pause or inquire further.” Greenberg disagrees, contending that his comment constituted an equivocal request for counsel sufficient to preclude all further questions except those directed to ascertaining whether he indeed desired counsel. This Court reviews
de novo
the lower court’s interpretation of the applicable legal standard.
See United States v. Alexander,
Once a suspect makes a request for an attorney, all questioning must cease and may not resume until an attorney is present, unless the suspect initiates an exchange with the authorities and knowingly and intelligently waives the right that he
*1472
had invoked.
Minnick v. Mississippi,
— U.S. —,
When a [suspect] makes an equivocal request for an attorney during a custodial interrogation, ‘the scope of that interrogation is immediately narrowed to one subject and one subject only. Further questioning thereafter must be limited to clarifying that request until it is clarified.’ Any statement taken by the state after the equivocal request for counsel is made, but before it is clarified as an effective waiver of counsel, violates Miranda.
Owen v. Alabama,
The threshold inquiry is therefore whether Greenberg’s statement to the interrogating officers constitutes an equivocal request for an attorney. The
Miranda
Court defined broad parameters for finding a request for counsel: the accused invokes the right by “indicat[ing] in any manner and at any stage of the process that he wishes to consult with an attorney before speaking.”
Miranda v. Arizona,
Greenberg’s statement to the interrogating officials—“I don’t know if I need a lawyer, maybe I should have one, but I don’t know if it would do me any good at this point”—clearly reveals that he was “contemplating exercising his right to have an attorney present.”
Towne,
The prophylactic reach of
Miranda
required the interrogating officer to clarify immediately Greenberg's equivocal statement: “where an accused gives ambiguous, vague, indefinite, or indecisive signals,” the interrogating officer must “follow[]up questioning to clarify his or her wishes.”
Towne
at 1109-10. Because the officer instead continued his questioning, the confession was obtained in violation of Greenberg’s
Miranda
rights.
See Cannady v. Dugger,
*1473
Greenberg’s next inculpatory statement was elicited during questioning by the Customs official. Although Greenberg again waived his
Miranda
rights, counsel still had not been made available to him. When an accused remains without the benefit of counsel, the accused’s earlier invocation bars further interrogation unless the accused “himself initiates further communication, exchanges, or conversations with police.”
Minnick,
2. Statement to Magistrate Judge
Greenberg made his third admission of guilt to a magistrate judge during his initial appearance in this case. See Fed.R.Crim.P. 5. Greenberg argues that the district court should have suppressed this statement either on the grounds that it was obtained in violation of his Sixth Amendment right to counsel or because the improperly obtained prior statements tainted his final admission of guilt. We disagree.
The Sixth Amendment right to counsel serves
“to
assure aid at trial,”
United States v. Gouveia,
The initial appearance is largely administrative. In Greenberg’s case, the court read the charges, ascertained his name, recited his
Miranda
rights, appointed counsel and set bail. Although the court in the initial appearance must consider the weight of the evidence against the defendant as one of many factors in setting bail,
3
the bail hearing is not a trial on the merits in which the guilt of the accused is adjudicated.
United States v. Dohm,
Greenberg argues that his confession in any event should have been excluded from evidence as “fruit of the poisonous tree.”
See Oregon v. Elstad,
The “fruit of the poisonous tree” doctrine may require exclusion of a subsequent confession only if the prior confession was obtained in violation of the Fifth Amendment.
Elstad,
In the instant case, Greenberg was entitled to the exclusion of his confession to the Customs official solely because the prophylactic reach of
Miranda
operated as a
per se
bar to all custodial interrogation until an attorney was provided. Since this confession was not “actually coerced,” it was obtained in violation of
Miranda
but not in violation of the Fifth Amendment. Thus under the “fruit of the poisonous tree doctrine” Greenberg's second confession cannot trigger the exclusion of his final admission of guilt.
See Miller v. Dugger,
Greenberg counters that his confession to the Customs official was in fact a product of coercion and thus in violation of the *1475 Fifth Amendment. Specifically, he argues that the Customs official threatened his family, and that this threat prompted him to make a confession. The district court rejected this allegation, finding that such a threat, if made, did not coerce Greenberg into making his confession.
We review determinations regarding the voluntariness of a confession for clear error.
United States v. Vera,
In the instant case, Greenberg alleges that the Customs official threatened his family by stating that “if you don’t cooperate with us, ten years can be a long time in jail. Anything can happen and something can happen to your family, something can happen to your mother, your father.” Greenberg’s subjective understanding aside, we find that the official’s statement does not represent a credible threat against Greenberg’s family.
See Agee v. White,
The interrogation session was otherwise free of inducements or coercive factors. Greenberg makes no allegation of any actual promises made in return for his cooperation. The Customs official recited Greenberg his
Miranda
rights and questioned him for only forty minutes.
See Miller,
Assuming
arguendo, however,
that the Customs official coerced his confession in violation of the Fifth Amendment, Greenberg still cannot prevail under the “fruit of the poisonous tree” doctrine. The doctrine dictates the suppression of a subsequent confession only if it was “tainted” by the coercion involved in the prior confession.
See Elledge v. Dugger,
Greenberg’s admission of guilt to the magistrate judge was therefore properly admitted into evidence. This final inculpatory statement, together with significant circumstantial evidence
(see infra
section 11(F)), constitute overwhelming evidence of guilt that renders harmless the district court’s erroneous admission of the two prior confessions.
See Chapman v. California,
B. Speedy Trial Act
Greenberg argues that an eighteen month interval between the return of his indictment and the commencement of his trial violated his statutory and constitutional rights to a speedy trial. This contention is without merit.
The Speedy Trial Act requires that a defendant’s trial begin within 70 days “of the information or indictment, or from the date the defendant has appeared before a judicial officer of the court, whichever date last occurs.” 18 U.S.C.A. § 3161(c)(1) (1985). Certain types of pretrial delay are automatically excluded from the Act’s time limits.
Id.
at § 3161(h). The Act excludes the period of delay between the filing of a motion and the conclusion of the hearing on that motion, regardless of the reasonableness of that delay.
See Henderson v. United States,
In the instant case, co-appellant Marin-Hernandez and co-defendant Barrero-Perez filed their motions for severance sixty-eight days after the return of their (and Greenberg’s) indictment. The district court held a hearing on the severance issue eighteen months later, on the day before commencement of the trial. Greenberg makes no attempt to demonstrate any prejudice suffered by his defense because of this delay, and our review of the record reveals no evidence that his defense was by any means encumbered. In fact, Greenberg during this period conducted an active motion practice that otherwise would have excluded at least five months from the Speedy Trial Act computation.
See
18 U.S.C.A. § 3161(h)(1)(F) (1985). We therefore find the eighteen month period reasonable under the second aforementioned test.
Cf. United States v. DeLuna,
*1477
Greenberg’s contention that the delays encountered before trial violated his constitutional right to a speedy trial is likewise without merit. The Supreme Court has articulated a four-part balancing test to determine whether there has been a violation of the Sixth Amendment: (1) the length of the delay, (2) the reason for the delay, (3) whether and how the defendant asserted his right to a speedy trial, and (4) the prejudice to the defendant.
Barker v. Wingo,
C. Posse Comitatus Act
Greenberg contends that the involvement of the United States Navy in his arrest constituted a violation of the Posse Comitatus Act that warranted dismissal of the indictment. 7 The Posse Comitatus Act provides:
Whoever, except in cases and under circumstances expressly authorized by the Constitution or Act of Congress, willfully uses any part of the Army or the Air Force as posse comitatus or otherwise to execute the law shall be fined not more than $10,000 or imprisoned not more than two years, or both.
18 U.S.C.A. § 1385 (West 1984). The Act by its own terms places no restrictions on Navy involvement with law enforcement agencies,
accord United States v. Yunis, 924
F.2d 1086, 1093 (D.C.Cir.1991); Schow
engerdt v. General Dynamics Corp.,
Even if the Act were construed to apply to the Navy,
see United States v. Ahumedo-Avendano,
D. Request for Jury Instruction
Greenberg next argues that the district court committed reversible error by refusing to offer an instruction that purportedly summarized his theory of the case. His instruction stated in relevant part:
It is the theory of the Defendant that at the time of his arrest that the vessel known as the Apache III was not subject to the jurisdiction of the United States and that he was not violating a United States law at the time of the alleged offense_ If you find that the defendant did not violate a United States law, you shall find him not guilty....
The lower court instead issued the following instruction:
You are also instructed that a claim of failure to comply with international law in the enforcement of this chapter may be invoked solely by a foreign nation, and a failure to comply with international law shall not divest a court of jurisdiction or otherwise constitute a defense to any proceeding or prosecution.
Reversible error for failure to give a requested instruction exists only if: “(1) the proffered instruction was substantially correct, (2) the requested instruction was not addressed in the charge actually given, and (3) the failure to give the instruction seriously impaired the defendant’s ability to present an effective defense.”
United States v. De La Vega,
E. Greenberg as a Career Offender
A defendant whose instant offense of conviction is either a controlled substance offense or a violent felony and *1479 whose record reflects at least two prior convictions for either drug offenses or violent felonies is classified as a “career offender” under section 4B1.1 of the sentencing guidelines. The district court found that in light of Greenberg’s prior convictions for attempted arson and armed robbery, his conviction for marijuana trafficking conferred career offender status. See U.S.S.G. § 4B1.1. Greenberg argues that the district court erred by declining to ascertain whether his conviction for attempted arson in fact involved physical violence. He also asserts that his 1973 armed robbery conviction is an ineligible predicate offense because it was committed over fifteen years before the instant offense of conviction. See U.S.S.G. § 4A1.2(e)(l). We find these arguments meritless.
Section 4B1.2(1) and Application Note 2 to section 4B1.1 designate arson as a crime of violence. Note 2 also states that qualifying predicate offenses include attempted crimes of violence.
See
U.S.S.G. § 4B1.1, Application Note 2. Further scrutiny of a prior conviction is unwarranted: “the analysis of a crime under [§ 4B1.1] should focus on the statute which defines the offense—evidence establishing the particular conduct of the defendant on the day the crime was committed does not bear on that inquiry.”
United States v. Gonzalez-Lopez,
The armed robbery conviction of 1973 was also a proper predicate offense because Greenberg was incarcerated for that offense within the fifteen year period prior to the instant offense. See U.S.S.G. § 4A1.2(e)(1). Greenberg served a prison sentence for the armed robbery conviction until August 15, 1979. 10
F. Sufficiency of the Evidence
Appellants Marin-Hernandez and Mendoza-Cecelia claim that the evidence was insufficient to prove their knowing participation in the offense of conspiracy to possess with intent to distribute marijuana. Mendoza-Cecelia also claims that the evidence was insufficient to support his conviction for possession with intent to distribute marijuana. Both appellants assert that they were merely present on the boat and that no evidence connected them to their crimes of conviction.
We review
de novo
questions concerning the sufficiency of the evidence.
United States v. Beale,
To prove a conspiracy, the government must demonstrate that an agreement existed between two or more persons to commit a crime and that the defendant knowingly and voluntarily joined or participated in the illegal venture.
See Jones,
Conspiracy and possession cases involving narcotics-laden vessels present repetitive fact patterns warranting special consideration.
See Garate-Vergara,
(1) probable length of the voyage, (2) the size of the contraband shipment, (3) the necessarily close relationship between captain and crew, (4) the obviousness of the contraband, and (5) other factors, such as suspicious behavior or diversionary maneuvers before apprehension, attempts to flee, inculpatory statements made after apprehension, witnessed participation of the crew, and the absence of supplies or equipment necessary to the vessel’s intended use.
Garate-Vergara,
Marin-Hernandez and Mendoza-Cecelia were aboard a relatively small vessel (37 foot) fully loaded with ninety-seven bales of marijuana. The marijuana was in plain view and completely filled the cabin area. The only place to sleep was on top of the bales, and drinking water was located in the cabin where the marijuana was found. The immense volume of marijuana moreover produced an overwhelming odor easily detected on the decks. The boat had no other cargo and few provisions. Arresting officers found Marin-Hernandez attempting to dispose of several pieces of false identification as well as instructions for operating the Loran radio.
See Garate-Vergara,
G. Motion for Severance
Mendoza-Cecelia contends that the district court erred by denying his motion for severance because the redacted version of Greenberg’s post-arrest statements violated his right of confrontation under the Sixth Amendment. He argues that despite the fact that all plural refer-
*1481
enees were changed to the singular, a reference within the statement to a “crew of six” necessarily implicated him in violation of
Bruton v. United States,
The Supreme Court in
Bruton
held that the admission of a “powerfully incriminating extrajudicial statement]” of a code-fendant violates a defendant’s Sixth Amendment right of confrontation even when the court instructs the jury to consider the confession only against the codefendant.
Id.
at 135-36,
The lower court in the instant case changed all uses of “we” to “I” and deleted all inculpatory references to the crew. 11 The redacted confession thus read as a first-person narrative of Greenberg’s activities. The single reference to the crew — “I had a crew of six” — did not describe the involvement of the crew in the smuggling operation. Although the jury was logically compelled to include Mendoza-Cecelia as one of the “crew of six,” the confession did not directly implicate the crew in the conspiracy. Therefore, unlike the redacted confessions in Hemelryck, Bennett, and Petit, the inference from Greenberg’s confession that Mendoza-Cecelia was uninvolved in the criminal activity was just as likely as the inference that he was a voluntary participant in the conspiracy. 12 Because the statement at most only indirectly implicated Mendoza-Cecilia, the district court properly denied Mendoza-Cecelia’s motion for severance.
III. CONCLUSION
For the foregoing reasons, we AFFIRM appellants’ convictions and sentences.
Notes
. Codefendants Robert Paul Souza, Jairo Dominguez, and Alvaro Dario Barrero-Perez entered guilty pleas prior to the commencement of trial.
. The
Towne
court discussed
Cherry
and
Fouche
at length and adopted their findings and analy-ses.
See Towne,
. Section 3142(g) of Title 18, United States Code (West Supp.1992) sets forth criteria for determining whether there are conditions for release, short of imprisonment, that will reasonably assure the appearance of the defendant at trial. Section 3142(g) states in relevant part that the judicial officer shall take into account:
(1) The nature and circumstances of the offense charged, including whether the offense is a crime of violence or involves a narcotic drug;
(2) the weight of the evidence against the person;
(3) the history and characteristics of the person, including—
(A) the person’s character, physical and mental condition, family ties, employment, financial resources, length of residence in the community, community ties, past conduct, history relating to drug or alcohol abuse, criminal history, and record concerning appearance at court proceedings; and
(B) whether, at the time of the current offense or arrest, the person was on probation, on parole, or on other release pending trial, sentencing, appeal, or completion of sentence for an offense under Federal, State, or local law; and
(4) the nature and seriousness of the danger to any person or the community that would be posed by the person’s release....
Id.
. The Fifth Amendment right to counsel is likewise of no avail to Greenberg in this instance.
The Miranda-Edwards
right to counsel is comprised of prophylactic measures intended to counteract inherently coercive pressures of custodial interrogation, pressures that might otherwise thwart a suspect’s desire to consult counsel when dealing with the police.
See McNeil,
. Although Greenberg has no constitutional right to counsel at his initial appearance, Rule 44(a) of the Federal Rules of Criminal Procedure provides that every defendant unable to retain counsel is entitled to “have counsel assigned to represent that defendant at every stage of the proceedings from initial appearance before the federal magistrate or the court through appeal, unless that defendant waives such appointment.” We do not interpret this rule to mean that a court must have appointed counsel prior to even this “initial” proceeding.
Accord Perez,
. Having determined the eighteen month delay reasonable under the second measure of reasonableness, we need not evaluate whether such a delay qualifies as reasonable under the remain
*1477
ing two tests. We note, however, that aside from the approximate five months of delay otherwise excludable from Greenberg’s Speedy Trial clock, the lower court was required to continue the trial three times, once because of conflicting obligations cited by Greenberg’s counsel.
See
18 U.S.C.A. § 3161(h)(8)(A);
United States v. Vasser,
. Greenberg also argues that the indictment should be dismissed for lack of subject matter jurisdiction. He contends that the reference to "possession with intent to distribute” in section 1903 of 46 U.S.C.A. necessarily means distribution in the United States. The statute specifically provides, however, that “[t]his section is intended to reach acts of possession, manufacture, or distribution committed outside the territorial jurisdiction of the United States."
See
46 U.S.C.A. § 1903(h);
see also United States v. Riker,
. Greenberg nevertheless argues that 10 U.S.C.A. § 374 (West Supp.1992) bars naval personnel from operating naval equipment for law enforcement purposes without the express authorization of the Secretary of Defense.
See id.
This section, however, must be read within the context of the entire chapter.
See United States v. Roberts,
. In any event) the Posse Comitatus Act provides no basis for the proposed remedy of dismissal of all charges.
See United States v. Yunis,
Alternatively, Greenberg argues that a violation of the Act warrants application of an exclusionary rule. This Circuit has declined to fashion an exclusionary rule until such time as widespread and repeated violations of the Posse Comitatus Act demonstrate a need for such sanction.
United States v. Wolffs,
. Greenberg also argues that the sentencing court clearly erred by refusing to give him a two-level reduction for acceptance of responsibility. The decision of the sentencing court “ ‘is entitled to great deference on review and should not be disturbed unless it is without foundation.'"
United States v. Ignancio Munio,
. The district court deleted Greenberg’s reference to his "recruiting" of the crew members and the following inculpatory passage: “The other crew members were there to help me out in the maintenance of the boat. They all knew what we were doing.”
. The former inference is consistent with Mendoza-Cecelia’s defense that he boarded the boat without knowledge of the contraband and that he never had a stake in the smuggling operation.
