Entrapment as a Criminal Defense

Entrapment is a recognized affirmative defense in American criminal law that applies when government agents induce a person to commit a crime that person would not otherwise have committed. This page covers the legal definition of entrapment, the two competing doctrinal tests used by federal and state courts, the factual scenarios in which the defense most commonly arises, and the evidentiary and procedural boundaries that determine whether the defense succeeds. Understanding entrapment requires distinguishing lawful undercover investigation from unconstitutional government overreach — a distinction that shapes outcomes across drug, weapons, cybercrime, and public corruption prosecutions.

Definition and Scope

Entrapment as a formal defense holds that the government cannot manufacture a crime and then prosecute the person it manipulated into committing that crime. The U.S. Supreme Court first articulated the federal standard in Sorrells v. United States, 287 U.S. 435 (1932), establishing that entrapment occurs when a government agent implants a criminal design in the mind of an innocent person. The doctrine was further refined in Jacobson v. United States, 503 U.S. 540 (1992), where the Court held that the government must prove beyond a reasonable doubt that a defendant was predisposed to commit the offense before the government's inducement began.

Entrapment is classified as an affirmative defense in criminal law, meaning the defendant bears the initial burden of producing evidence that government inducement occurred. Once that threshold is met, the burden in federal courts shifts to the prosecution. The defense is distinct from other constitutional challenges such as Fourth Amendment suppression motions or Brady material disclosure obligations — entrapment does not challenge how evidence was gathered but rather contests whether the criminal act itself was government-manufactured.

The defense applies only to government agents or those acting at their direction. Private-party inducements — a friend daring someone to commit a crime, for example — do not constitute entrapment under federal or any state standard.

How It Works

Two competing doctrinal tests govern entrapment analysis across U.S. jurisdictions:

The Subjective Test (Federal Standard and Majority of States)

The subjective test, applied in federal courts and adopted by the majority of states, centers on the defendant's predisposition. Under Sherman v. United States, 356 U.S. 369 (1958), courts ask whether the defendant was ready and willing to commit the offense before the government approached them. The inquiry is defendant-specific — prior criminal record, statements made before the sting, and the speed with which the defendant agreed to participate are all admissible evidence of predisposition.

The prosecution must establish two elements to defeat an entrapment claim under this test:

1. That the defendant was predisposed to commit the crime independently of the government's conduct.
2. That the government's inducement did not create a disposition that did not previously exist.

The Objective Test (Minority of States)

A minority of states — including California under Penal Code principles and a handful of others — apply an objective test. This test does not examine the specific defendant's mental state. Instead, it asks whether the government's conduct would have induced a normally law-abiding person to commit the crime. Under this standard, a defendant with a lengthy prior record can still succeed on an entrapment defense if the government's tactics were sufficiently coercive or manipulative.

Subjective vs. Objective Test — Key Differences:

The Model Penal Code (American Law Institute, §2.13) adopts a version of the objective standard, framing entrapment as conduct by a government agent that employs methods of persuasion or inducement that create a substantial risk that the offense will be committed by persons other than those who are ready to commit it.

Common Scenarios

Entrapment claims arise most frequently in undercover law enforcement operations. The following categories represent the most litigated factual contexts:

1. Drug Sting Operations
Undercover agents posing as buyers or sellers engage targets in drug transactions. Courts in cases following Jacobson scrutinize whether the government targeted an individual who was already participating in drug markets or whether it created a new criminal opportunity for someone with no prior involvement. Drug crime defense cases account for a significant portion of entrapment litigation at both federal and state levels.

2. Weapons and Explosives Stings
Federal Bureau of Investigation (FBI) and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) conduct operations involving the sale of illegal firearms or simulated explosive devices. Under 18 U.S.C. § 922, charges for illegal weapons transfers frequently involve undercover purchases. Defendants raise entrapment when agents repeatedly solicited reluctant targets over extended periods.

3. Child Exploitation and Online Solicitation Operations
Law enforcement agencies including the Department of Homeland Security (DHS) and the Internet Crimes Against Children (ICAC) Task Force network operate online undercover investigations targeting solicitation of minors. Entrapment claims in this category typically fail when the defendant initiated sexually explicit contact, but succeed in narrow cases where agents injected explicit content into neutral conversations and then escalated. Computer and cybercrime defense attorneys frequently raise entrapment alongside other constitutional challenges in these prosecutions.

4. Public Corruption Stings
Undercover operations targeting public officials — often conducted by FBI agents posing as lobbyists or contractors offering bribes — generate recurring entrapment claims. Courts generally reject these defenses when the official solicited the bribe or accepted it without hesitation but give them more weight when agents made repeated, pressure-laden offers before the official agreed.

5. Terrorism-Related Operations
Post-2001 FBI operations have produced a category of cases in which informants or undercover agents engaged individuals expressing extremist views, provided them with resources, and then facilitated a plot. Federal courts have examined these cases extensively; entrapment defenses have rarely succeeded when defendants took affirmative operational steps, but the doctrine remains contested in these prosecutions.

Decision Boundaries

Whether an entrapment defense succeeds or fails turns on a set of discrete legal thresholds that courts apply consistently across jurisdictions:

Threshold 1: Was the inducing party a government agent?
The defense is unavailable unless the inducing party was a sworn officer, a paid government informant, or a private individual acting under explicit government direction. This threshold question is frequently dispositive and intersects with constitutional rights of the accused when informant relationships are disputed.

Threshold 2: Was there inducement beyond mere opportunity?
Providing an opportunity to commit a crime is not entrapment. Courts distinguish between government agents who create opportunity (permissible) and those who apply persistent pressure, fraud, threats, or appeals to sympathy to overcome reluctance (potentially entrapment). The number of contacts, the nature of the appeals, and whether the defendant initially refused are all documented in trial records.

Threshold 3: Was the defendant predisposed? (Subjective jurisdictions)
Prior convictions for the same category of offense, recorded statements expressing willingness to commit the crime, and prompt agreement without hesitation are the three factors most consistently cited by prosecutors to establish predisposition. Defendants who required 10 or more contacts before agreeing have historically had stronger entrapment claims than those who agreed on first contact.

Threshold 4: Is entrapment a jury question or a judge question?
In federal courts and most states applying the subjective test, entrapment is a jury question once the defendant meets the threshold of production. Under objective-test jurisdictions, some courts treat it as a matter of law decided by the judge. This procedural distinction affects whether the criminal trial procedure will result in jury instructions on entrapment.

Threshold 5: Does raising entrapment waive other defenses?
In federal practice, raising entrapment implicitly concedes that the defendant committed the charged act — because the defense argues the act was government-induced, not that the act did not happen. This strategic concession eliminates independent not-guilty pleas on the underlying conduct, making entrapment a defense that must be weighed carefully against alternatives within the broader criminal defense strategies available in a given case. Defense counsel often evaluate this alongside burden of proof standards that govern whether the prosecution must disprove predisposition or the defendant must affirmatively prove government overreach.
