Well, to be fair, a break-in is a special circumstance, different from a simple purse-snatching or something. There's generally an assumed threat to your life if someone breaks into your house, and so it's more understandable. However, if someone, for example, steals your wallet at a flea market or something, I just don't see how you can justify shooting them in the back as they're running away. Your property has value, yes, but not more value than someone's life, regardless.
1. Personal opinion. Every issue of life and death is not outlined in the Constitution. Makes pretty good sense for a long life in my book. If someone breaks in, how the fuck do you know what their intentions are? People high on crack have been known to do weird shit. I am not there to psycho-analyze ANY reason they decided break in. I assume it means to harm me or my family. Like I said, the second they decided to break in, they put a value on their life...not me.
For one, my house is pretty small, so if I'm shooting someone inside my house, there's a good chance that I'm at very close range. So it's more reasonable to aim at specific parts when you're at close range. If you have a bigger house, things might be different. But I'm of the philosophy that if you can shoot to disable rather than shoot to kill, you should.
Well, aim for that knee cap or shoulder (which is right next to his friggin head btw...don't miss). I consider myself a decent shot, but during the helter skelter horror of a home invasion, I make no promises of being able to hit the broad side of a barn. Maybe you have found a way to make the criminal hold still while your deftly make that sniper shot from 40 feet just winging him.
