Which of the following is a procedural defense commonly invoked to challenge government conduct in obtaining evidence or an arrest?

• A. Insanity
• B. Alibi
• C. Entrapment
• D. Self-defense

Answer: (C)

Entrapment is a defense centered on police conduct and the way evidence or an arrest is obtained. It arises when government agents induce or persuade a person to commit a crime they would not have otherwise committed, with the aim of prosecuting them. This defense protects against government overreach by arguing that the crime was manufactured by law enforcement rather than genuinely chosen by the defendant. A key idea is that if the defendant was predisposed to commit the crime on their own, the entrapment claim isn’t valid, and the evidence remains admissible. The other options fit different kinds of defenses—insanity concerns mental state at the time, alibi asserts the person wasn’t present at the scene, and self-defense justifies the use of force—so they do not address how law enforcement’s conduct affects obtaining evidence or an arrest.
