People should have a legal obligation to shoot robbing thieves breaking into your house, don't fucking rob houses.
Exactly this. If you've got uninvited people on your property mooching about, especially in the early hours of the morning, all bets are off. They shouldn't be there it's as simple as that. There are so many horror stories about burglars being violent, that they have to expect people will respond to their presence with that thought in the forefront of their minds. Don't want to be injured or killed? Stay the fuck off other people properties.
