In this case we are again called upon to review convictions resulting from an FBI investigation of corrupt police officers engaged in the protection and transport of narcotics in the Commonwealth of Puerto Rico. 1 This appeal is brought by three co-defendants convicted on charges stemming from a conspiracy to provide police protection for cocaine shipments. Defendants-Appellants Santos-Rodriguez (hereinafter “Santos”) and Medina-Sanchez (hereinafter “Medina”) were both police officers at the time of the offenses. A jury convicted all three defendants of conspiring to distribute in excess of five (5) kilograms of cocaine, in violation of -21 U.S.C. § 846. Defendants Diaz-Diaz (hereinafter “Diaz”) аnd Santos were also convicted of carrying firearms during and in relation to a drug trafficking offense, in violation of 18 U.S.C. § 924(c)(l)(a)(I). The district court sentenced Diaz to a prison term of 295 months. Santos received a sentence of 248 months of imprisonment. A prison sentence totaling 235 months was imposed on Medina. All three defendants also re *132 ceived a supervised release term of five years.
In this appeal defendants allege a variety of errors, both at trial and sentencing. At trial, the district court is alleged to have committed error by: (1) admitting video recordings of meetings between the defendants and the government’s cooperating witness; (2) refusing to grant a mistrial after the prosecutor made improper comments to the jury; (3) failing to, sua sponte, instruct the jury concerning the defense of entrapment; and (4) denying defendant Diaz’s motion for judgment of acquittal on the firearm charge. At sentencing, the district court is alleged to have committed error by: (1) improperly delegating its authority to the probation officer; (2) applying the four-level “Organizer or Leader” enhancement to Diaz’s sentence; (3) denying Diaz’s request for a two-level adjustment for “Acceptance of Responsibility”; (4) denying Diaz’s request for a downward departure due to his health condition; and (5) sentencing the defendants in violation of United States v. Booker. 2
1. Factual Background
The evidence presented at trial stems from an FBI “sting” operation. In October of 2000, Santiago Enmanuel De Leon Lasala (a/k/a “Avanti”) approached the FBI seeking to serve as an informant. The FBI agents told Avanti that they were interested in police officers who served in protective roles for drug smuggling operations. Avanti, posing as a drug trafficker, attempted to find officers willing to perform such duties. Eventually, Avanti met defendant Diaz. Diaz told Avanti that he had police officers on his payroll willing to escort and protect cocaine shipments.
In order to get Diaz to produce these officers, undercover FBI agents posed as members of - the drug trafficking cartel. On December 6, 2000, with the assistance of Avanti, Diaz met with an undercover FBI agent, whom he believed to be a member of the cartel. Diaz offered to provide police officers to escort a shipment of cocaine for the cartel. In this and subsequent meetings with the undercover agent, Diaz negotiated the details of the arrangement. Diaz recommended the route to be used in transporting the cocaine from Fajardo to San Juan. Diaz also negotiated the fee that he and his officers would receive, ultimately agreeing on $5,000 per person.
In order to obtain evidence of the defendants’ participation in the conspiracy, the FBI, with the assistance of Avanti, arranged a covert system of surveillance. Using FBI provided funds, Avanti rented a storefront from which he taught music lessons. The FBI outfitted this music school with hidden cameras, microphones, and recording devices. Although the devices could be monitored from an outside location by FBI agents, operation of the system was left in the hands of Avanti. Avanti activated the devices by operating a switch on the exterior of the building before entering it to meet with the defendants. Aftеr the meetings were over, he could turn off the devices by using -the switch when exiting.
On April 27, 2001, Diaz introduced Avanti to defendants Santos and Medina. This meeting took place at the music school and was recorded. The same men met again on June 4, 2001, to finalize plans for transporting the shipment of cocaine. This too was recorded at the music school.
*133 On June 5, 2001 the defendants traveled to the Fajardo Mall. Medina and Santos each entered a separate unlocked vehicle, retrieved the keys from beneath the floor mat, and drove the cars to San Juan. Although the defendants believed that these vehicles contained cocaine, each vehicle contained ten kilograms of flour wrapped in duct tape. As the defendant police officers drove the cars filled with the flour, Diaz followed them in another vehicle.
After completing the transport, the defendants returned to the music school to receive their payment. While waiting there with Avanti, they were again recorded. The cameras recorded Santos removing a revolver from his waistband. The devices also recorded defendant Diaz’s statement “He’s armed, I’m armed, and he’s armed,” referring to his eo-eonspirators.
II. Analysis
Each defendant raises challenges to his conviction and subsequent sentence.
A. Challenges to Convictions
1. Defendant Medina
Medina argues that his conviction must be vacated because the evidence upon which the jury found him guilty was obtained illegally. Prior to trial, Medina moved to suppress recorded conversations between himself, his co-conspirators, and thе government’s paid informant, Avanti, on the grounds that they were obtained in violation of the Fourth Amendment’s prohibition against unreasonable searches and seizures, and Title III of the Omnibus Crime Control and Safe Streets Act’s prohibition on electronic surveillance, 18 U.S.C. § 2510 et seq. That motion was denied and the recorded conversations were admitted at trial.
In reviewing the denial of a motion to suppress, we review the district court’s factual findings for clear error, and the district court’s legal conclusions
de novo. United States v. Marshall,
On the facts presented in this case, the Fourth Amendment challenge clearly fails. The Fourth Amendment does not protect an individual from having his or her conversation recorded with the consent of another person who is a party to the surveilled conversation.
Lopez v. United States,
Defendant’s claim that the recordings violated Title III is, for similar reasons, without merit. As this court has
*134
previously recognized, “Congress, in its wisdom, chose to insert a myriad of exceptions and restrictive definitions into Title III, purposely leaving certain ... communications unprotected.”
Griggs-Ryan v. Smith,
It shall not be unlawful under this chapter for a person acting under color of law to intercept a wire, oral, or electronic communication, where such person is a party to the communication or one of the parties to the communication has given prior consent to such interception.
18 U.S.C. § 2511(2)(c).
Thus, we have held that “[t]he statute permits the taping of conversations without approval if a person who is a party to the conversation gives prior consent.”
United States v. Font-Ramirez,
Defendant does not contend that Avanti failed to consent to the taping of the conversations. Instead, he attempts to challenge the effect of that consent by arguing that Avanti’s relationship with the government was of such a nature that he became an “agent” of the government, as opposed to a “cooperating witness.” With respect to application of this statute, however, defendant has provided only a distinction without a difference. Were we to classify Avanti as a government agent it would make no difference, as the statute applies to those who act “under color of law.” See 18 U.S.C. § 2511(2)(c). The statute does not distinguish a “cooperating witness” from a “government agent.” Accordingly, the consent of Avanti was sufficient to bring the recordings admitted at trial within the above referenced exception, and there was no error in allowing their admission.
Medina next argues that his conviction should be vacated because of improper remarks made by the proseсutor during defendant’s closing argument. Defense counsel, during his closing argument, commented upon the government’s failure to call one of the FBI agents as a witness, rhetorically asking:
... by the way, have you before you the most important agent of all, Agent Louis Feliciano, the case agent? He was, from the very start, he can explain a lot of things, he can clarify many doubts. He was in charge of the ease all throughout. Does it matter at all to you that or it doesn’t matter?
In response to this line of argument, the government objected and, in the presence of the jury, stated:
Your Honor, counsel can call this witness as well. After the court asked the prosecutor to repeat his objection, he stated in the presence of the jury:
Counsel can call this witness, just like the United States.
The defendant’s attorney timely objected and moved for a mistrial. Although the motion was denied, the judge promptly instructed the jury that defendant had no obligation to present evidence and that the burden of proof remained on the government. 3
*135
Defendant now argues that the district judge should have granted his motion for a mistrial. We review denial of a motion for a mistrial for an abuse of discretion.
United States v. Fierro,
The first question presented is whether the prosecutor’s statements were improper. Defendant argues that they were improper because they shifted the burden of proof by insinuating to the jury that the defendant had the burden to present evidence of his innocence. He does not argue, and appears to have no basis on which to do so, that the prosecutor’s statements were an improper comment on the defendant’s failure to testify.
We have previously held that a prosecutor is not entirely forbidden from commenting on the defendant’s failure to produce evidence supporting the defendant’s stated theory.
See United States v. Kubitsky,
After reviewing the prosecutor’s remarks and the context in which they were made, we find that they were improper. Defense counsel’s argument was not aimed at having the jury draw the inference that the government did not call the agent because his testimony would have been harmful to its case. Instead, the argument was that the government had failed to present all of the evidence needed to prove Medina guilty beyond a reasonable doubt. In this context, the prosecutor’s comments could have the effect of shifting the burden оf proof, rather than refuting a requested inference and, therefore, were improper.
The question remains, however, whether the district judge abused her discretion in refusing to grant a mistrial. We conclude that she did not. The prosecutor’s remark, though technically improper, approached the margin of propriety. Moreover, any risk that the jury may have improperly considered the remark was immediately and effectively addressed by the judge’s prompt and thorough instruction to the jury that the burden of proof remained with the government.
See United States v. Smith,
2. Defendant Santos
Santos argues that his conviction must be overturned because it was the result of entrapment. The first issue to be resolved
*136
is whether this court may consider defendant’s entrapment argument even though he failed to raise it before the district court. This court has long held that “an issue not raised before the trial court cannot be raised for the first time on appeal.”
United States v. Uricoechea-Casallas,
At least one circuit has concluded that there is no such affirmative duty on the part of the district court to give an entrapment instruction absent a request from the defendant.
See United States v. Lewis,
Before an entrapment instruction may be given to the jury, the defendant bears the “entry level” burden of pointing to “hard evidence, which if believed by a rational juror, would suffice to create a reasonable doubt as to whether government actors induced the defendant to perform a criminal act that he was not predisposed to commit.”
United States v. Young,
Defendant in this ease is unable to make any showing that government actors improperly induced him into these offenses. As this court has made clear, it is not sufficient that the government provided the defendant with the opportunity to commit the crime. A defendant must demonstrate an opportunity “plus” some other conduct, such that it implicates concerns of government overreaching. See
Young,
3. Defendant Diaz
Diaz argues that there was insufficient evidence presented to the jury to justify his conviction for the firearm offense. Because Diaz moved for a judg
*137
ment of acquittal at the close of all the evidence, he has preserved the issue for appeal.
See United States v. Van Horn,
On appeal the government does not argue that Diaz physically possessed a firearm himself, but rather that he is vicariously liable fоr the firearm offense under a theory of
Pinkerton
liability.
See Pinkerton v. United States,
In order to prove that a co-conspirator committed the crime of carrying a firearm in relation to a drug trafficking offense, the government had the burden to prove that: (1) the co-conspirator committed the predicate drug trafficking crime ...; (2) that the co-conspirator knowingly carried or used a firearm; and (3) that the co-conspirator did so during and in relation to the specified predicate offense.
See United States v. Flecha-Maldonado,
The second element was also satisfied, as the government presented a video recording showing defendant Santos brandishing a firearm while the group was waiting for payment at the music school. Finally, the third element was satisfied because there was evidence that this firearm was brandished both during and in relation to the conspiracy. At the time the firearm was observed the conspiracy was still ongoing, as the co-conspirators were seeking to obtain their payment. Furthermore, a reasonable jury could find, beyond а reasonable doubt, that the carrying of that firearm was in relation to that conspiracy because the evidence showed that the co-conspirator’s role in escorting the cocaine was to provide protection. Thus, the government provided sufficient evidence that a co-conspirator committed the firearm offense.
In order for defendant Diaz to be held vicariously liable for this conduct, however, the government must also prove that the carrying of the firearm was in furtherance of the conspiracy, and that this act was foreseeable by the defendant.
See Pinkerton,
*138 B. Sentencing
Defendant Diaz
Diaz challenges the terms of his supervised release, arguing that the district court erred in delegating to the probation officer the authority to determine the number of drug tests he will be subject to and whether, upon a positive result, he must engage in a rehabilitation program. It is clearly established law in this circuit that such delegations are improper,
e.g., United States v. Melendez-Santana,
The question before the court, then, is whether that portion of the sentence must be vacated due to the error. Recently, a panel of this court, sitting
en banc,
clarified that unpreserved delegation errors of this type remain subject to traditional “plain error review.”
See United States v. Padilla,
Under the plain error standard applicable to delegation errors the defendant must “limn circumstances indicating a reasonable probability that the trial court, but for the error, would have imposed a different, more favorable sentence.” Id. at 221. As this court has recognized, such a demonstration of prejudice in cases involving this type of error is almost impossible. Id. Nonetheless, the court has carefully reviewed the record before it for any such indication. Having found none, we conclude that defendant has failed to make the requisite showing of prejudice.
Defendant Diaz next challenges the trial judge’s determination that he was subject to an enhancement as an “organizer or leader” pursuant to U.S.S.G. § 3Bl.l(a). This court may only review that determination for clear error.
United States v. Laboy,
The guidelines provide that such an enhancement is appropriate if the defendant “was an organizer or leader of a criminal activity that involved five or more participants or was otherwise extensive.” U.S.S.G. § 3Bl.l(a). Thus, in order to apply the enhancement the sentencing court must determine that the defendant had both the requisite participation in the criminal activity, and that the criminal activity itself was sufficiently extensive. See id. Here Diaz challenges only the determination that his participation was sufficient for the enhancement to apply.
The Guideline comments provide “relevant factors” for determining whether or not the requisite participation exists, specifically:
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.
The evidence at trial demonstrated that Diaz’s conduct satisfies many of the above listed criteria. The trial court was justified in finding that he had, after promising that he could provide corrupt police officers to protect a cocaine shipment, actively recruited Police Officers Santos and Medina. The record also supports the conclusion that Diaz’s participation continued to a large degree. Evidence showed that he attended most of the meetings in which the amount of shipments of cocaine and trans *139 portation of the cocaine were discussed. Diaz even instructed the undercover agents of the best route for transporting the drugs. Although he did not receive a larger share of the “fruits of the crime,” Diaz exercised some decision-making authority as he was the one who made contact with the undercover agents to negotiate what payment he and his accomplices would receive. Finally, after recruiting the officers, assisting in the planning, and negotiating the fee, Diaz personally oversaw the transport of the sham cocainе by traveling with his accomplices on the route he had helped choose. On this record it cannot be said that the trial judge committed clear error.
For similar reasons this court will affirm the district court’s denial of Diaz’s request for a downward adjustment for “Acceptance of Responsibility,” pursuant to U.S.S.G. § 3El.l(a). First, we note that a defendant who takes his case to trial “greatly diminishe[s] his chances of receiving [such an] adjustment.”
United States v. Baltas,
As evidence of his acceptаnce of responsibility, defendant points to his objection to the pre-sentence report, in which his counsel asserted;
It is represented that Mr. Diaz fully accepts his responsibility as he now understands that his decision to go to trial was due to his perception that he was somehow legitimately assisting or helping the cooperating witness (Avanti).
Although this statement purports to be an acceptance of responsibility, it is nothing of the sort. Rather than admitting that he committed the crimes alleged, Diaz admits only the conduct and denies the knowledge that makes it a crime. The record shows that even at sentencing Diaz continued this denial. During the sentencing hearing, defendant’s counsel asserted that defendant still maintained that, rather than having been involved in criminal conduct, he had been aiding the gоvernment informant in order to assist the federal government. 4 There is nothing in this record which demonstrates that defendant ever took responsibility for any of his criminal conduct. 5 Consequently, refusal of the downward adjustment was not clear error.
The district court’s refusal to grant defendant a downward departure due to his health condition is also affirmed. In reviewing the denial of a departure request this court’s review is limited to whether the sentencing judge misconstrued its authority.
United States v. Mejia,
*140 we review de novo a district court’s determination of its authority to depart, but lack jurisdiction to review a discretionary decision not to depart from the Sentencing Guidelines.
Id.
The record before us indicates that the sentencing judge did not misconstrue her authority. During sentencing the court correctly tоld counsel that a downward departure could be granted if the defendant could make a showing that he would be unable to receive adequate treatment while serving his sentence with the Bureau of Prisons (hereinafter “BOP”). This is a proper statement of the district court’s authority under the sentencing guidelines.
See United States v. Martin,
C. Booker Error
Because all three of the defendants were sentenced under the pre-Booker mandatory guidelines, we review to determine if we must vacate any or all of the sentences. The government stipulates to error as to each sentence, but argues that we must affirm because there has been no resulting prejudice.
The first step in our inquiry is to determine who bears the burden of persuasion on the issue of prejudice. This turns on whether the defendants below “preserved” the error by objecting to thе sentence. In considering claims of
Booker
error we have been somewhat lenient, construing any objection argued on the basis of
Apprendi v. New Jersey,
With regard to defendants Diaz and Santos, there was no such objection and it is clear that neither has preserved the issue. Accordingly we review their sentences only for plain error, and those defendants bear the burden of demonstrating “a reasonable probability that the district court would impose a different sentence [that is] more favorable to the [defendants] under the new ‘advisory Guidelines’
Booker
regime.”
Antonakopoulos,
Defendant Medina, on the other hand, did object at sentencing on the grounds that his sentence violated
Apprendi.
Although the government argues that this objection was only sufficient to “partially preserve” the issue (a distinction that we will address later in our analysis), the government concedes that it bears the burden to show, beyond a reasonable doubt, that the district court would impose the same sentence under the advisory guidelines.
See United States v. Vazquez-Rivera,
Having determined the parties’ requisite burdens, we turn to the record to decide whether those burdens have been met.
*141 1. Defendant Santos
In arguing that there is a reasonable probability that the district court would impose a lesser sentence under the advisory guidelines, defendant Santos points only to the fact that he was sentenced to the minimum permitted under the then mandatory guidelines: We have previously held, however, that a sentence at the low end of the guidelines,
without more,
is insufficient to make the requisite showing under our plain error jurisprudence.
United States v. Kornegay,
2. Defendant Diaz
The record also fails to indicate that there is a reasonable probability that defendant Diaz would receive a more favorable sentence under the advisory guidelines. Like Santos, Diaz was also given the lowest possible sentence under the then existing mandatory guidelines. Unlike Santos, however, the record indicates that Diaz suffers from a serious illness. We have previously recognized that such circumstances may, in some cases, make it mоre likely that the district court would depart downward under the now advisory guidelines.
See United States v. Heldeman,
3.Defendant Medina
As noted above, the government concedes that it bears the burden to show beyond a reasonable doubt, that the district court would apply the same sentence under the now advisory guidelines. Although we have noted that this is an extremely difficult burden, it is not an impossible one.
Vazquez-Rivera,
The government first argues that all of the sentencing factors relied upon by the district court were supported by overwhelming evidence. The question, however, is not whether the district judge would apply the same
factors
under the advisory guidelines, but whether she would reach the same
sentence
based upon those same factors.
See Vazquez-Rivera,
Next, the government asserts that this defendant’s “partial” preservation of the Booker error is further evidence that the judge would apply the same sentence under the advisory guidelines. The government labels this a “partial” preservation because defendant Medina objected to only one of the sentencing factors applied by the court. Essentially, the government argues that this is significant because, even *142 if his objection at sentencing had been sustained, he still could have been sentenced under the mandatory guidelines to the same sentence that he ultimately received, 235 months imprisonment. Although this fact may be interesting, we fail to see, and the government has failed to articulate, why it is significant. The error in sentencing was not the district court’s application of factors requiring judicial factfinding, it was doing so under a mandatory guideline system. For purposes of determining prejudice, it is the compulsory status of the guidelines that must be proven harmless, and the “partial” preservation claimed by the government bears no logical relation to that question.
Finally, the government argues that a comment made by the judge during sentencing demonstrates that she would apply the same sentence under the advisory guidelines. Although we have recognized that such comments may be persuasive evidence that the
Booker
error was harmless,
see United States v. Melendez-Torres,
At sentencing, defendant’s attorney argued that it was unfair that although defendаnt was acquitted of the firearm charge, the judge’s application of the two-level enhancement for the presence of a firearm would result in his receiving a sentence that was substantially similar to his co-defendants who were convicted of the firearm offense. In response to this argument, the judge stated that “[cjonviction of the firearms charge would have entailed a consecutive sentence on that charge.” The government appears to argue that this statement demonstrates the judge’s belief that the sentence given to defendant Medina was appropriate. We, however, do not so construe it. The judge’s statement to counsel describing the effect of a conviction for the firearm offense was a correct statement of the applicable law. It contained no statement of belief or opinion, and does not assist the government in meeting its burden.
Finally, we note that there is reason to doubt that defendant would receive the same sentence under the advisory guidelines because the district judge sentenced defendant Medina to the lowest sentence permitted by the then mandatory guidelines.

See United States v. Casas,
III. Conclusion
For the reasons stated above, we VACATE the sentence of defendant Medina and REMAND for his resentencing. In all other respects, the judgments of convic *143 tion and the sentences imposed by the district court are AFFIRMED.
Notes
. Our previous cases arose from a reverse sting operation entitled "Honor Perdido".
See United States v. Sanchez-Berrios,
.
Booker,
. The entire instruction was as follows:
My instruction to you is this: I told you from the beginning of the case when we were selecting the jury, and I tell you now, I told you in my preliminary instructions when you were a jury, and I tell you now, that the burden of proof is on the government to prove every single element of the offense charged-in this case there are two-that burden has to be met as to each count
. Counsel stated;
Mr. Diaz was firmly convinced that he was somehow aiding the United States government through Mr. Avanti, and that he thought he had an agreement with Mr. Avanti, that Mr. Avanti would explain to the federal government, the federal agents everything that was going on.
. Defendant's attempt to blame the probation officer for failing to give him an opportunity to confess his responsibility is unavailing. In his meeting with the probation officer, it was defendant who chose to remain silent regarding the criminal conduct because his attorney was not present. Furthermore, this was not the only opportunity for defendant to disclose his acceptance of responsibility, as he could have submitted an affidavit to the court prior to sentencing. Finally, defendant himself exercised his right to address the court at sentencing and chose to omit any statement accepting responsibility. Any failure to record the alleged acceptance of responsibility falls squarely upon defendant.
. Consideration of this fact with respect to defendant Medina
is
entirely consistent with our affirmance of the sentences of Diaz and Santos. Although a sentence at the low end of the guideline range is of some relevance in determining the likelihood that the district court would apply the same sentence under the advisory regime, that fact alone is insufficient to malte an affirmative showing of prejudice.
