Peter, an undercover police agent, was trying to locate a laboratory where it was believed that methamphetamine, or "speed"—a controlled substance—was being manufactured illegally. Peter went to Mary’s home and said that he represented a large organization that was interested in obtaining methamphetamine. Peter offered to supply a necessary ingredient for the manufacture of the drug, which was very difficult to obtain, in return for one-half of the drug produced. Mary agreed and processed the chemical given to her by Peter in Peter’s presence. Later Peter returned with a search warrant and arrested Mary. Mary was charged with various narcotics law violations. Mary asserted the defense of entrapment. Should Mary prevail? Why?
