He didn't shoot the man. To shoot the man, your gun needs to be pointed at him when you pull the trigger. This is not to advocate warning shots, but there wasn't anything inherently criminal about a warning shot in this case, based on the facts known. Remember, the other guy was a felon caught in the act.
