I heard them say today that she wasn't being charged b/c she has mental problems...my response to that is, would a mental person who hurt someone get off free b/c he was mental? Of course not. He might not see any jail time, but he would be locked away. Crystal is likely not physically dangerous to anyone, but she is dangerous in that she almost ruined (and did severely damage) three young lives with her lies. She should be punished for that and also receive some psychiatric help if it is so needed.
You're right, if she physically assaulted the boys she'd be facing charges for sure. Add in the fact that this is (I think) her 3rd false allegation, and she SHOULD be facing some type of legal action which would hopefully ensure psychiatric help and prevent her from messing up more people's lives. I also hope she is able to care for her new baby adequately, but I am sure she could benefit from psychiatric care.
