 The case was a virtual replay of "Sorrells v. United States", the 1932 case in which the justices had first recognized entrapment as a defense.As in that case, all agreed the defendant had been entrapped, but the majority and a separate concurrence were at odds over what the best grounding for the entrapment defense was.In late August 1951, Kalchinian, a recovering drug addict, met Sherman at a doctor's office where they were both getting treatment for their addiction.
