I really disagree with you. In general, I think prosecutors are overzealous but in this case, I think the woman should be charged, in fact, I think she should face murder charges. I think an example should be made of her, nationwide, so that the next young fool will not, under any circumstances, point a loaded gun at anyone and pull the trigger — unless it is to stop a crime! She deserves a long long time in prison. (Or attack any person with any other dangerous object no matter how foolish and innocent the reason may seem to be.)
If someone asks you to break the law and you do it ... then you should face the consequences. The fact that he asked her to do it doesn't change much in my book.
