I hope you're not safe because you're locked in again :-)

That's an upsetting thing to go through though. I remember when our neighbors across the street, the guy and his brother shot the back window of our camper out when we weren't home. Fortunately our good next door neighbor was on his porch and heard the popping of the gun shooting and sneaked closer to watch. The idiots came across the street to check their marksmanship and the good neighbor confronted them! When we got back he told us what had happened and had us call the police but we couldn't find any of the pellets inside the camper so the police and good neighbor went over but all the police could do was tell them it's against the law to shoot across the street like that! It turned out they were pissed about something we couldn't do anything about. I started feeling really unsafe, like they could going to start shooting at my cat or something.

Hope your guy gives up or somebody can catch him or do something about it.
