Where I see the problem with this is how can a person depend on a bystander to intervene in stopping some thug from severely injuring you after dragging you out of your car. There is no way to tell how a situation like this is going to end up. How much of a beating are you going to take before you decide it's enough and at that point are you still capable of defending yourself?

"If they are intending to kick your ass, you'd have to make a reasonable determination on where this is going to end up...not an eviable position to be in."

How is it possible to make a reasonable determination on where an assault is going to end up. This is such a grey area. I just think that once you enter a persons vehicle or home and physically contact that person with intention of violence the line has been crossed and victim should have the benefit of the doubt.
