Answer:he can assert the defense of: ENTRAPMENT
Step-by-step explanation:
Entrapment is a defence that one can use to say that the alleged criminal activities that they are sued for were committed under being coerced to do such an action. It means particular tactics were used that led to someone finally commiting a crime, such as being threatened. It usually occurs when the policeman forced a defendant to commit a crime.
