Its not kidnapping if you are protecting human life. In some states you can even use lethal force to protect someone from bodily harm. I'm not saying go shoot up a hospital. What I'm saying is that some point, you snap, and morally you have to do something regardless of what happens to you. This country literally dies for people like this every day and if we don't make a stand for other people there won't be anybody left to do it for us. Just imagine the emotional state of that grandmother. The jury would have a hard time reconciling this fact with the law.
