The Lawyer's Secret(1931)

Sailor Joe Hart, who is spending his shore leave at a gambling joint, sells his gun to young Laurie Roberts after losing terribly. After Hart again loses his last dime, he leaves the joint and steals a car in order to return to his ship. Later that night, a tough gambler named "The Weasel" convinces Laurie, who also lost badly, that Baldy, the joint's owner, is crooked, and they both return to the joint to break open the safe. During the holdup, The Weasel kills Baldy with Joe's gun and, after being picked up for speeding, Joe is arrested for murder.
