Entrapment as a Criminal Defense in the U.S.

Entrapment is a recognized affirmative defense in American criminal law that allows a defendant to contest criminal liability when government agents induced the commission of an offense that the defendant would not have otherwise committed. This page covers the legal definition of entrapment, the two competing tests used by federal and state courts, the scenarios in which the defense most frequently arises, and the doctrinal boundaries that determine when the defense succeeds or fails. Understanding entrapment requires distinguishing lawful law enforcement investigation from conduct that crosses into manufacturing crime — a line that courts have drawn through more than a century of constitutional interpretation.

Definition and Scope

Entrapment exists as a defense because the criminal justice system does not permit the government to create the very offense it then prosecutes. The U.S. Supreme Court first articulated a federal entrapment doctrine in Sorrells v. United States, 287 U.S. 435 (1932), where the Court held that Congress could not have intended statutes to punish individuals who were induced by government agents into violating the law. The Court reaffirmed this framework in Sherman v. United States, 356 U.S. 369 (1958), which remains a foundational citation for the federal subjective test.

Entrapment is classified as an affirmative defense — meaning the defendant carries the initial burden of producing some evidence of government inducement before the prosecution must disprove the defense beyond a reasonable doubt. It is categorically distinct from defenses such as self-defense or the insanity defense, which challenge the nature of the act itself or the defendant's mental state; entrapment does not deny the conduct but attributes its origin to government misconduct.

The defense applies only to conduct induced by government actors: federal agents, state law enforcement officers, or private individuals working as paid informants under government direction. Misconduct by a purely private party does not constitute entrapment under established federal doctrine.

How It Works

Two distinct tests govern entrapment analysis in the United States, and a defendant's jurisdiction determines which applies:

Subjective Test (Federal Standard and Majority of States): This test — established in Sorrells and Sherman and codified in the Model Penal Code § 2.13 — focuses on the defendant's predisposition. Courts ask whether the defendant was ready and willing to commit the crime before government contact, or whether the government's inducement implanted the criminal idea in an otherwise innocent mind. If the defendant was predisposed to commit the offense, the defense fails regardless of the degree of government involvement.
Objective Test (Minority of States, including California for certain contexts): This test asks whether the government's conduct would likely have induced a normally law-abiding person to commit the crime. The defendant's individual predisposition is irrelevant; the inquiry centers on the character of the government's tactics. States adopting this approach treat entrapment as policing courts against systemic law enforcement overreach rather than as protection for the particular defendant.

Under the subjective test, once a defendant raises entrapment, the prosecution may introduce evidence of the defendant's prior criminal history, prior participation in similar crimes, and statements of willingness to engage in the charged conduct — all to establish predisposition. This use of prior-act evidence is explicitly addressed under Federal Rules of Evidence, Rule 404(b), which otherwise restricts character evidence.

The entrapment defense is distinct from the due process-based "outrageous government conduct" doctrine, which the Ninth Circuit has recognized in limited circumstances when law enforcement behavior is so extreme that it shocks the conscience regardless of predisposition. Federal courts have applied this doctrine narrowly and have declined to dismiss charges on that basis in the large majority of cases where it is raised (U.S. Department of Justice, Criminal Resource Manual § 645).

Common Scenarios

Entrapment claims arise most frequently in the following categories of criminal defense litigation:

Undercover drug operations: An officer or informant approaches a target, repeatedly solicits a drug sale despite initial resistance, and the defendant ultimately completes the transaction. Courts examine how many times the government requested the transaction and whether the defendant expressed reluctance. Drug crimes under federal law generate a substantial proportion of entrapment claims.
Sting operations targeting sex offenses: Federal law enforcement agencies including the FBI and the Department of Homeland Security Investigations (HSI) conduct undercover online operations in which agents pose as minors. Defendants who initiate contact independently and demonstrate prior intent face virtually no viable entrapment defense; defendants who respond to aggressive solicitations may raise inducement arguments. Federal sex offense statutes include 18 U.S.C. § 2422 (coercion and enticement), under which sting prosecutions are common.
Terrorism-related investigations: The FBI has conducted undercover operations in which informants approach individuals, provide equipment, and facilitate a plot before arrest. Courts applying the subjective test in cases such as United States v. Cromitie, 727 F.3d 194 (2d Cir. 2013) have upheld convictions where evidence established independent predisposition. Terrorism offense law presents some of the sharpest contested applications of entrapment doctrine.
White-collar and public corruption stings: The FBI's ABSCAM operation in the late 1970s and early 1980s, which led to the conviction of 1 U.S. Senator and 6 members of the House of Representatives, remains the largest documented political corruption sting in U.S. history. Courts affirmed those convictions, finding predisposition. White-collar crime prosecutions continue to use undercover methods.

Decision Boundaries

Whether an entrapment defense succeeds turns on clearly defined doctrinal thresholds:

Government Inducement vs. Government Opportunity
Courts distinguish providing an opportunity to commit a crime (lawful) from inducing a crime (potentially unlawful entrapment). An undercover officer offering to purchase drugs from a known dealer provides opportunity. An officer who targets a person with no prior drug history, applies psychological pressure over weeks, and invents a compelling personal narrative to overcome repeated refusals crosses into inducement territory.

Predisposition: The Central Inquiry Under the Subjective Test
Evidence courts accept to establish predisposition includes: (a) prior convictions for the same or similar offenses, (b) the defendant's immediate, uncoerced agreement to engage in the offense, (c) defendant-initiated contact with the agent, and (d) prior statements or communications indicating criminal intent. Evidence that weighs against predisposition includes documented reluctance, government persistence across multiple contacts, and absence of any prior criminal history relevant to the charged conduct.

The Timing Rule
Predisposition must predate substantial government contact. As the Supreme Court held in Jacobson v. United States, 503 U.S. 540 (1992) — where the Court reversed a conviction after the government had solicited a defendant through 26 months of mailings — predisposition cannot be established by the government's own inducements. The government must show that criminal intent existed before its agents became involved.

Jury vs. Judge
Under the subjective test, entrapment is ordinarily a jury question because predisposition is a factual finding. A defendant who raises entrapment cannot simultaneously deny committing the act charged, since the defense concedes the conduct and contests only its government-manufactured origin. This tactical constraint — noted in the context of burden of proof standards — means defense counsel must choose between inconsistent strategies before trial.

Informant-Specific Limits
The entrapment defense applies equally when a government-directed informant (as opposed to a sworn officer) induces the offense. The role of law enforcement agencies in directing informant activity is examined to determine whether the informant was acting as a government agent at the time of the alleged inducement.
