I'd really have to agree with most of you on this one. I wouldn't feel guilty in the least bit if I had to kill someone who was trying to hurt me or my family. The thing is though, if someone opens your door to your car or home, SHOOT TO KILL. Otherwise, you may end up like some, behind bars for simply defending you and your family. And yes, if someone simply OPENS the door of your car, you have the right to shoot/kill them because your car is a extension of you and your property. I've spoke with several cops about this and they all say, if you are in that situation, shoot, but shoot to kill so they can't come back with some sob story and your the one in prison. My home defense is a .44 Magnum Desert Eagle and a Cobray Mac11.
Heres a picture of a Mac11 IDENTICAL to mine.
