What happens if the all mighty auto taser decides to malfunction? Ull get a nice jolt of current running through ur body possibly stopping that pacemaker, knoking u out, u go into spasm, or higher up ur high blood pressure to the point where the heart explodes into action...... Now, of course we dont want that to happen but "what if". The odds of one of them tasers tripin is definantely possible. Call me paranoid but ill pass on that and stick with the basics.
