I'm personally in a helpless position. I can't run away from anybody. This makes me feel just a tad more uneasy, for instance, driving in my van. Since I do display the handicap placard very prominently, and I do park in all the handicap places, someone might think that I'm a much easier mark and could not defend myself.
It's a shame that one has to break the law in order to protect themselves, but I'm willing to take that chance. If trouble comes to me, I don't intend to just sit there or lay there screaming 'help me.' I'm going to grab, as fast as I can, for my loaded weapon. And believe me, I have made up my mind that in order to protect my life I will shoot to kill.
