Sting and Reverse-Sting Operations in Federal Cases

How Sting and Reverse-Sting Operations Work in Federal Cases

In an ordinary sting, undercover agents or informants pose as buyers and let a target sell contraband or commit the offense. In a reverse sting, the roles flip: the Government offers to sell or supply the contraband, and the target is arrested for buying or attempting to acquire it. Agents also stage entirely fictitious plots, such as robbing an invented drug stash house.

These techniques share a common legal footing. Federal law has long permitted the Government to use artifice and stratagem to catch those engaged in criminal enterprises, and infiltration of criminal activity is a recognized and permissible means of investigation. The Government may go undercover, use paid informants, provide equipment, and even supply items of value without automatically crossing a legal line. What the operation cannot do is manufacture a crime in the mind of a person who was not already willing to commit it.

Because the structure of a sting shapes the available challenges, it helps to identify which model applies. A buy-bust and a reverse sting raise the entrapment question differently, and an invented stash-house robbery raises its own predisposition and sentencing issues. This satellite focuses on the operational mechanics of stings and the specific doctrines that govern them, which are distinct from the general framework of the parent motion.

Is a Reverse Sting Entrapment?

A reverse sting is not entrapment under federal law, so long as the defendant was predisposed. The fact that a government agent served as the seller does not change the analysis, because the controlling issue is the defendant’s willingness to commit the crime, not who played which role in the transaction.

The Fifth Circuit stated this directly in United States v. Knight, holding that a reverse sting in which officials sell illegal drugs to those charged is not entrapment, and that the general acceptability of the technique has been confirmed repeatedly. The court emphasized that the issue is the predisposition of the accused, not the encouragement by the Government or even the fact that officials served as the sellers. A defendant who is ready and willing to buy cannot escape liability by pointing out that his supplier turned out to be an agent.

That predisposition requirement is the real battleground in a reverse-sting case. Everything covered on the companion predisposition page applies here: the defense must produce evidence of inducement and a lack of predisposition, and the Government must then prove predisposition beyond a reasonable doubt. If the target sought out the deal, negotiated eagerly, or arranged financing on his own, the reverse-sting label gives him nothing. The operation itself is lawful; only a genuine absence of predisposition can defeat it.

When the Government Supplies the Contraband

Agents sometimes supply the very contraband at the center of the charge, whether a drug precursor, the finished narcotic, or the target of a staged theft. Standing alone, that supply does not create an entrapment defense or a due-process bar when the defendant was predisposed. The Supreme Court settled the point for predisposed defendants decades ago.

In Hampton v. United States, a government informant supplied the heroin that the defendant then sold to other agents. The Court held that the entrapment defense was unavailable because the defendant’s predisposition was established, and it rejected the argument that supplying contraband is a per se denial of due process. The plurality reasoned that where the defendant is a willing participant, the remedy for any police overreach lies in prosecuting the officers, not in freeing an equally culpable defendant. The table sorts common sting structures by who supplies what and how each is typically challenged.

Supply is therefore a factor in the totality of the circumstances, not an automatic defense. It carries the most weight when combined with a passive defendant and pervasive government control, which is the domain of the separate outrageous-conduct standard.

Fictitious Stash-House and Robbery Stings

In a fictitious stash-house or robbery sting, agents invent the crime itself, describing a nonexistent drug house or courier and recruiting the target to rob it. Courts have upheld these operations against entrapment claims where the defendant showed the readiness to participate, treating the invented target as an opportunity rather than an inducement.

The Fifth Circuit addressed a staged armed-robbery sting in United States v. Stephens. The defendant argued that the Government pushed the plan toward a more violent crime than he preferred, but the court found no evidence that he hesitated once the plot became an armed robbery. It held that a stated preference for a lesser, non-violent offense is not relevant when the defendant promptly avails himself of the opportunity to carry out the greater one. Prompt, willing participation in the invented plot showed predisposition and defeated the request for an entrapment instruction.

These cases illustrate why invented-crime stings so rarely produce a viable entrapment defense. The scenarios are designed to test willingness, and defendants who negotiate roles, recruit crews, or bring weapons demonstrate exactly the readiness the doctrine looks for. The more promising challenges to a stash-house sting usually lie elsewhere: in the due-process outrageous-conduct theory, addressed on its own page, or in the sentencing arguments discussed next, where the Government’s control over the imaginary drug quantity becomes the focus.

Sentencing Entrapment and Sentencing Factor Manipulation

Even when a sting supports a conviction, defendants argue that agents structured it to inflate the sentence, for example by demanding larger drug quantities or a more violent plan than the target proposed. These theories are called sentencing entrapment and sentencing factor manipulation. In the Fifth Circuit, neither is an established defense.

The court declined to adopt sentencing entrapment in United States v. Washington, where the evidence showed the defendant had supplied far more than he claimed, refuting any predisposition to deal only in small amounts. In United States v. Tremelling, the court explained it had not expressly accepted sentencing factor manipulation, and that a district court’s discretion in determining relevant conduct is a sufficient check on the Government’s ability to influence a sentence by bringing larger amounts to a deal. Stephens reaffirmed that the circuit has never recognized sentencing entrapment and that, even if it did, the theory would require true entrapment or overbearing and outrageous conduct.

The practical takeaway is that a quantity or severity argument is usually pressed as a request for a variance under 18 U.S.C. § 3553(a) or a challenge to the relevant-conduct calculation, rather than as a freestanding defense.

Three Ways to Challenge a Sting Operation

A sting can be attacked on three fronts, and choosing the right one depends on the facts. Entrapment goes to the jury and turns on predisposition. Outrageous government conduct is decided by the court as a matter of law. Sentencing arguments accept the conviction but contest the Government’s influence over the punishment.

The entrapment route is the most common and is litigated at trial and the charge conference, where the reverse-sting and stash-house cases above apply. The outrageous-conduct route is raised before trial as a motion to dismiss the indictment under Federal Rule of Criminal Procedure 12, and it succeeds only in the rarest circumstances, as the due-process satellite explains. The sentencing route, framed under 18 U.S.C. § 3553(a), asks the court to discount an artificially inflated quantity or severity even though the Fifth Circuit has not adopted sentencing entrapment as a defense.

Each avenue demands a different record. Entrapment needs proof of reluctance and inexperience; outrageous conduct needs proof of pervasive government control and a passive defendant; a sentencing argument needs a clear picture of what the target actually proposed before agents escalated.

What the Case Law Says

These decisions—verified against primary sources—control how this issue is litigated. Every case still turns on its own facts.

• Hampton v. United States, 425 U.S. 484 (1976) — Entrapment is unavailable to a predisposed defendant even when a government informant supplied the contraband, and such supply is not a per se due-process violation.
• United States v. Knight, 917 F.2d 1 (5th Cir. 1990) — A reverse sting, in which officials sell drugs to those charged, is not entrapment; the issue is predisposition, not that agents served as sellers.
• United States v. Stephens, 717 F.3d 440 (5th Cir. 2013) — Prompt participation in a government-staged armed-robbery sting shows predisposition; a preference for a lesser offense does not establish lack of predisposition.
• United States v. Washington, 44 F.3d 1271 (5th Cir. 1995) — The court declined to adopt sentencing entrapment where evidence showed the defendant supplied larger quantities, refuting any predisposition to deal only small amounts.
• United States v. Tremelling, 43 F.3d 148 (5th Cir. 1995) — The Fifth Circuit has not expressly accepted sentencing factor manipulation; a court's discretion over relevant conduct checks the Government's ability to inflate a sentence.
