Well I am sorry to say that I do not have a whole lot of experience with this. But if he did get into legal trouble and he is in the united states, the state will grant him an attorney if he cant afford one. if he can somehow tell his attorney all that you have just told us then they can order a mental evaluation to see that he really is sick. then that will somehow play into what he is charged with in court and he will probably be forced by the governement to seek the help, and they will most likely set that up for him. Sorry i cannot be of more help!!

Good Luck x
