All the more reason why Ms. Mangum should be prosecuted to the fullest extent of the law. Why should genuine victims suffer in the future because of some misplaced sensitivity to Ms. Mangum's delicate mental state?
The attorney general said they won’t prosecute her because they think she believes all the various stories she told. There are only a couple of ways her behavior could be excused in this fashion. One is that she is genuinely mentally ill. Another is that the prosecutors noticed that she was repeatedly drunk when she was interviewed and they don’t want to embarrass themselves further.
