I actaully had a similiar thing happen to me. Some drunk tried crawling into my sons window. He thought it was the window of the high school girl two doors down. He could hardly stand but was smart enough to back away upon seeing a 45 pointed at him.

The guy then went to neighbors and was going to urinate in the driveway. Changed his mind and drove away.

As you indicate it isn't always necessary to shoot someone. Guns can be used to coerce compliance ~ through the threat of using them.
