Threatened by whom? As pointed out already, his personal trainer can't institutionalize him. My comment "Unless of course you think "they" have some undue influence over medical admissions" was meant to point out the underlying racism, and stupidity, of people using the trainer's single tweet as a defence of, and excuse for, KW.
For the record I'm not accusing you of being anti-semitic. The "he's a victim of crimes, they are threatening a repeat" is a line used by lots of people who are though and "they" is doing a lot of heavy lifting there. Maybe stating what you think is going on rather than this nudge nudge wink wink routine might be clearer?
