Love it!
I got broken into once when I was home. Loser punk had a crowbar, and thought the home was unoccupied. I rushed him and scared the living daylights out of him.
Chased his butt off with the crowbar and then called the police. They didn’t find him, despite the fact that this was about 5 blocks away from the station.
So, 9-1-1 is pretty useless. Self defense is the key.
