Slightly off topic anecdote alert: A few years ago some smackheads tried a home invasion on my elderly dad, who was silly enough to open the front door at 3am. They hit him over the head with a bar of some kind, but they chose the wrong ex sawmiller to play with. He picked one of them up and threw him headfirst down a flight of stairs, the other one ran for his life. When the cops came it was pretty much high fives all round, there was no suggestion that my dad might be in any trouble resulting from his actions, but I guess they were "country cops". Now my dad's neighbours stand well back after knocking on the door!
