Yeah and he signed a contractual agreement stating (as I imperfectly state) that he is coherent enough to seek future help. It is possibly that he could have faked rehabilitation, but at the same time there should have been an extensive background check in this young man's history of psychological disorder. Not just concerning his writings but perhaps his family, if he has any in the States.  the only reason he was referred to a mental health facility was due to the continual annoyance of a female student. Apparently, he constantly "bugged" her and she reported it to the campus police on several occasions I believe.

It may be possible that during his time in receiving outside help he could have acted as if he was rehabilitated but there is also the possibility he wasn't.
