A scenario where a citizen drives a bank robber away under threat is an example of which defense?

The scenario described, where a citizen drives a bank robber away under threat, exemplifies the defense of duress. Duress occurs when an individual is forced to commit an act against their will due to the immediate threat of harm to themselves or others. In this case, the driver faces a threat from the bank robber, which compels them to assist in the crime out of fear for their safety or the safety of others. This defense is rooted in the idea that the person acted not out of free will but under compulsion due to the imminent threat they were facing.

Other concepts, such as enticement, intimidation, and entrapment, do not accurately describe this scenario. Enticement typically involves encouraging someone to commit a crime through offers of reward, while intimidation refers to actions intended to instill fear to influence behavior. Entrapment occurs when law enforcement induces a person to commit a crime they would not ordinarily commit, which does not apply in this situation where the driver is responding to an immediate threat from a criminal.
