I'd agree with themachine that it's not suicide per se but I think that goes to a bigger question of what is suicide, death by hanging, too many pills, death by cigarettes, death by soda. Then as an aside, the religious aspect to that being so stupid that they'd bless the guy dead of lung cancer but damn the guy who consciously overdosed. Such judgmental bullshit.
Whether suicide consciously attempted or simply fate tempted or not, was that incline increased by any anti-gay harassment of the "therapy". So even if not a technical suicide as is the holy reprieve of those who knowingly smoke themselves to death, is there a contributory factor which might be criminally investigated?
I'm not sure about the arbitration here. Did the kid sign himself in, being an adult or did the mother sign something as well. And if he was an adult, did her signature mean anything. Why would she be bound to the technical legalities of something her adult kid signed up for? Had he been declared incompetent that she had to sign for him or did she sign under duress? Was she scammed into signing? She hadn't signed herself up for the program which would bind her to arbitration so what stops her from suing those assholes?
As to the courts ordering the kid to a religious institution, this is fucking bullshit. The separation of church and state needs to be reinstalled into the framework of this country as was intended by our founders and from which it has been aborted.
