You figure that the gun will have some srt of magical power, so when your roommate comes through the door, you shoot him. Upon being shot, your roommate yelps in agony and bleeds out. Your neighbor Earl hears thjis and runs to your door. He sees the scenario, runs off, and calls the police. You are trialed and found guilty, given a lifetime in jail.
Never assume with genies, kids.
