Stung by a sting, defendants Solomon Philip Panitz and Andrew Stewart Baum-wald received little balm from the United States District Court for the District of Maine. After that court denied various pretrial motions, each defendant pled guilty, conditionally, see Fed.R.Crim.P. 11(a)(2), and then appealed. Finding no prescription for the soothing unguent of reversal, we affirm the judgments below.
I. BACKGROUND
We set forth the general background of the sting and then particularize appellants’ involvement, mindful that the essential facts are not seriously disputed.
A. The Sting.
In November 1988, with the aid of two informants (0010 and 0011), the Coast Guard intercepted and seized 10,000 pounds of Colombian marijuana on the high seas. The marijuana was taken first to Puerto Rico, then to Maine. At that point, a Drug Enforcement Administration (DEA) agent had 0011 call the suspected smuggler of the illicit shipment, one Michael Goldin, to announce that the contraband had arrived as scheduled. Entourage in tow, Goldin *1269 flew to Boston on November 20, rented a car in an assumed name, drove to Maine, and registered at a local hotel (using the same alias).
A team of federal and state officers awaited his arrival. Informant 0011 introduced Goldin to Bansmer, an undercover operative. Bansmer took Goldin to a purported “stash house” near Newcastle, Maine. Goldin inspected the marijuana, stated that he had a list of twelve potential buyers, and took samples for display. The next day Goldin told one of the informants that six customers, identified by first name or description only, were en route to Maine. He also stated that he was still soliciting clients.
Blissfully unaware that he was dealing with a gang composed exclusively of federal and state lawmen, Goldin devised a plan for distributing the marijuana. He would make a series of vehicles available to his accomplices (agents all), turning over the keys. The agents would drive each vehicle, as received, to the place where the marijuana was being stored, 1 stuff it with whatever amount of marijuana Goldin specified, park at a prearranged spot, and return the keys to Goldin. The smuggler would then complete the transaction with the customer, exchanging the drug-laden vehicle for the balance of the agreed price.
Unbeknownst to Goldin, the agents added a new chapter to his script: the loaded vehicles were kept under constant surveillance. When a vehicle was claimed and driven away, it was followed. At a point sufficiently distant from the scene that the “real” criminals (like Goldin and the remaining customers) were unlikely to be alerted, a traffic stop would be accomplished by uniformed officers, the vehicle’s occupants arrested, the vehicle searched, and the contraband repatriated. No arrest or search warrants were procured.
B. Appellants’ Involvement.
We move now from the general to the particular. On November 21, Goldin told one of the undercover agents that Baum-wald had arrived in Maine, accompanied by two confederates, and had given Goldin two sets of car keys — keys to a BMW and a Ford, respectively. Although Baumwald had already paid for the marijuana, delivery was deferred until the next day at the agents’ behest. On November 22, Goldin handed over both sets of keys. The automobiles were driven away from the base hotel (where Baumwald had taken a room), stocked with marijuana, and returned to the hotel parking lot.
At 1:30 p.m. on November 22, one of Baumwald’s companions, Antonia Dinolfo, entered the Ford and proceeded to drive south on the Maine Turnpike. She was stopped and arrested at a predetermined point. The car was searched and the marijuana seized. About an hour later, Baum-wald and his remaining cohort, Rosen, entered the BMW. Surveillance officers followed them south on the Maine Turnpike to Mile 24, where the scenario was reenacted.
Early that evening, Goldin gave the keys to a Chevrolet to an agent, with instructions for loading. The automobile was returned to the hotel parking lot at about 8:30 p.m. It was not immediately retrieved. Shortly after midnight, the agents chose to reveal their identity to Goldin. 2 Caught dead to rights, he agreed to cooperate. At that time, Goldin told the lawmen that Panitz and his brother had come to Maine. The Chevrolet remained under surveillance. An hour or two later, Solomon Panitz entered the car and drove it away. When stopped, it was searched and the 10 bales of marijuana reclaimed.
II. PROCEEDINGS BELOW
The sting operation gave rise to multiple indictments. Panitz was charged with con *1270 spiracy to distribute in excess of 50 kilograms of marijuana in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(C), 846, and with the related substantive offense, possession of more than 50 kilograms of marijuana in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(1)(C). Baumwald was charged with the same types of crimes in a separate indictment. Both men were also charged with aiding and abetting. 18 U.S.C. § 2. By order of the district court, pretrial proceedings in all cases involving Goldin’s customers were deemed consolidated.
Though a flood of pretrial motions ensued, only two sets are germane to these appeals. Early on, defendants moved to dismiss the indictments by reason of outrageous government misconduct and sought an evidentiary hearing in connection therewith. The district court denied the motions.
United States v. Baumwald,
No. 89-00002, slip op. (D.Me. June 19, 1989) (unpublished)
(Baumwald I).
Motions to suppress physical evidence were also filed. A suppression hearing was held on June 21. The court thereafter issued a memorandum denying the motions.
United States v. Baumwald,
III. THE AUTOMOBILE SEARCHES
Both appellants assign error to the denial of suppression motions questioning the lawfulness vel non of the automobile searches. As described in Part 1(B), supra, the officers, without obtaining warrants, searched both Panitz’s Chevrolet and the BMW in which Baumwald was travelling. Although the searches occurred at different times and involved different vehicles, they share a common provenance and the same legal principles control.
Defendants’ lament has three parts. The first posits the absence of “exigent circumstances” sufficient to justify the warrant-less searches.
See generally United States v. Curzi,
We find these lyrics, though sung with great gusto, to be out of harmony with both the facts and the law. Factually, the record tends to support the district court’s thesis that the vehicle searches were accomplished under sufficiently exigent circumstances, not deliberately created by the government, to justify forgoing a trip to the magistrate.
See Baumwald II,
*1271
Generally speaking, warrantless searches require both probable cause — that is, a well founded conclusion “that an offense has been committed and ... sound reason to believe that a particular search will turn up evidence of it,”
United States v. Aguirre,
It is clear that, under the “vehicle exception” to the Fourth Amendment’s warrant requirement, the necessary predicate for law enforcement officers’ warrantless search of a motor vehicle is that they have probable cause to believe that the car contains contraband or other evidence of criminal activity.
See Carroll v. United States,
As the Court’s position has crystallized, the lower federal courts, by and large, have come to conclude, often
sub silentio,
that so long as the vehicle search is supported by probable cause, no particular exigency (beyond the inherent mobility of
any
motor vehicle) need exist.
See, e.g., United States v. Cruz,
This court has already rejected the need for an independent showing of exigency, at least by implication. Thus, in
United States v. Moscatiello,
That ends the matter. Because defendants do not challenge the district court’s finding that the police had probable cause to stop the vehicles, search them, and arrest the occupants, it is immaterial whether exigent circumstances were present.
IV. THE OUTRAGE CLAIM
Panitz complains that the government’s conduct of the sting operation was so outrageous that it infracted his constitutionally assured right to due process of law. 4 The district court resolved this claim on alternate grounds: defendants’ lack of standing, Baumwald I at 7-8, and the absence of governmental conduct “go[ing] beyond fundamental fairness.” Id. at 6. Because either of these findings is fully dis-positive of Panitz’s contention, we choose to address only the latter, more substantive point.
The Supreme Court has not foreclosed the possibility that the government’s active participation in a criminal venture may be of so shocking a nature as to violate a defendant’s right to due process, notwithstanding the defendant’s predisposition to commit the crime.
See United States v. Russell,
The conduct challenged here — the DEA’s interception and seizure of the drugs, its employment of government resources and facilities to complete the smuggle and bring the contraband to Maine, its use of informants as go-betweens, and its casting of constables to play the parts of gang members — does not come close to the level of egregious unacceptability that would be necessary to implicate the Due Process Clause. The reverse appears true: the structuring and implementation of the sting operation seems appropriate under the totality of the proven circumstances.
See, e.g., United States v. Gianni,
In the ongoing struggle between law enforcers and the underworld, the use of ingenuity is not foreclosed to the government. The police may, within reason, employ guile and clever tactics. When investigating narcotics enterprises, such stratagems are frequently the option of choice; by their very nature, drug rings are extremely difficult to penetrate and detect without undercover intrusion. Not surprisingly, then, courts have consistently recognized that greater government involvement is allowable in such cases.
See, e.g., id.
at 432,
In sum, the law enforcement practices utilized in this case were neither fundamentally unfair nor offensive to principles of due process. Government infiltration of criminal activity, after all, is a “recognized and permissible means of investigation.”
Russell,
Panitz’s claim that he was wrongfully denied an evidentiary hearing is equally unavailing. It is self-evident that “[djistrict courts are busy places and make-work hearings are to be avoided.”
United States v. Cannons Engineering Corp.,
There was no abuse of discretion in rejecting the request for an evidentiary hearing on the issue of outrageousness. The material facts were not in dispute. According to the proffer below and Panitz’s brief on appeal, defendants thought a factfind-ing hearing might shed light in three areas: (1) the degree of governmental involvement in the sting and the amount of public funds expended; (2) Goldin’s status, including when he became an informant; and (3) the timing of the customers’ participation in the operation. The first and third points seem wholly superfluous. The record leaves no doubt but that the DEA orchestrated the sting from the moment the marijuana shipment was intercepted 5 until some time after Panitz was arrested. The government’s involvement was considerable; the details of that involvement — how many agents were used or how much money was spent — make no meaningful difference. By the same token, Panitz has not indicated in what way the involvement of Goldin’s other customers — involvement which, in any event, is well defined in the existing record — had any bearing on his situation.
Goldin’s status is, of course, a horse of another color. But there is not a whisper of a hint of an intimation that Goldin became aware of the DEA’s presence, and began cooperating, at any time before the early morning hours of November 22 — well after the Chevrolet had been driven to Maine, turned over to Goldin, and loaded with marijuana. Appellant’s suggestion that perhaps Goldin was cooperating at an earlier date is unanchored in any fragment of discernible fact. A district court is not obliged to schedule an evidentiary hearing on the basis of conclusory allegations, vague insinuations, unsupportable inferences, rank speculation, opprobrious epithets, or any combination of the foregoing. Because Goldin’s role was not legitimately in doubt, testimony was not required.

V. CONCLUSION
We need go no further. “Injustice is relatively easy to bear; what stings is justice.” H.L. Mencken, Prejudices, Third Series (1922). There was no injustice here. The judgments below should be, and hereby are,
Affirmed.
Notes
. In truth, the DEA agents stockpiled the marijuana shipment at the Maine state police barracks. As we have said, "irony is no stranger to the law.”
Amanullah v. Nelson,
. Up to that point, seven persons (including Baumwald, Rosen, and Dinolfo) had been arrested. Several more people, including Solomon Panitz and his brother, Norman, were arrested after Goldin agreed to cooperate. Because none of the codefendants are parties to these appeals, we refrain from discussing either their involvement or the specific charges against them.
. While we need not address appellants’ "anticipatory search warrant" construct, we note in passing that the federal cases they cite concern defendants who complained about the govern-merit’s decision to seek a warrant in anticipation that a forecast set of facts would materialize.
See, e.g., Hale,
. Although Baumwald’s conditional guilty plea reserved the right to appeal on this ground, his brief makes no mention of the issue. He has, therefore, abandoned it.
See United States v. Zannino,
. Panitz has not suggested that the government’s involvement began earlier, or that the DEA arranged to have the marijuana sent from Colombia.
