In criminal law, entrapment is a practice whereby a law enforcement agent induces a person to commit a criminal offense that the person would have otherwise been unlikely to commit. It is a type of conduct that is generally frowned upon, and thus in many jurisdictions is a possible defense against criminal liability.Depending on the law in the jurisdiction, the prosecution may be required to prove beyond a reasonable doubt that the defendant was not entrapped or the defendant may be required to prove that they were entrapped as an affirmative defense.Sting operations are fraught with ethical concerns over whether they constitute entrapment.
