It's sad that legal ramifications even have to be discussed. If someone were stealing someone else's car, which may be their only means of getting to and from work, you should be able to do just about anything you want to the thief other than killing him. (A good a$$ kicking would be best) Standing in front of a car that has been started by a thief is a BAD idea. Puts you both in a bad situation. If the thief is breaking into your house/apartment, then deadly force can be used, PERIOD, no ifs, ands or buts.
If corrupt lawyers and judges didn't run our legal system, I think there would be FAR fewer criminals with an added bonus of people not worrying if someone is going to sue them if they protect their property and family. Some common sense would be nice! Ok, I'm done with my rant....for now.
