If I felt as if my life or my family's life was in danger I would shoot to kill. I know the laws where I live if someone breaks into your house you can shoot them. In the past 6 months there has been about three people killed where I grew up from breaking into homes, and you know what?......people have thought twice before they go breaking down someone's door.
A man(who had been through CC training) in my community shot a home intruder, four conditions met. Did not kill intruder. Intruder then sued the homeowner --paraded character witnesses that said this boy was only a thief, would not hurt anyone(yet still conveyed threat to life of homeowner). The homeowner won, however he did have to foot the legal bills for his defense.
We had a famous case in the UK, two guys broke into a framhouse the farmer shoot them killing one and injuring the other. The farmer went to jail after his release the injured intruder sued but didn't win but he receives gov. benefits as he says he is unable to work because of a him being left with a limp (from bullet) and mental stress/epression
