I couldn't believe it either! But then I've also heard of burglars who have got themselves injured breaking in, and sued the owner of the house!
The only thing I've heard that was OK was a guy who wired up his car to give anyone who tried to break into it a huge electric shock. He had notices on the car to that effect. Well someone did try and break in, and tried to sue the owner of the car. And failed.
But as for burglars, hell, we may as well invite them in, and give them dinner too - I mean it probably comes under civil rights or something. Quite unbelievable.
I'm not saying its right to shoot someone, and maybe he did overdo it a bit, but how did he know the people breaking in weren't going to try and kill him? Whats he meant to do, wait until he is injured or dying and then at least he will be OK in court?
We are getting closer and closer to the ridiculous legal state of the USA.
