I live in LA and hospital patients are routinely dumped. I know it sounds odd but th ehospitals get people that are homeless so they don't want to leave.
This, however, sounds like a tragic mistake.
My sis is a Physical therapist here in LA. She said the homeless guys in the hospital get 5***** treatment, and are in and out and in and out, as they don't take care of themselves.
Altho this seems to be terrible upon first reading, just where WOULD you 'return to their home' a homeless guy? To the condos they built for winos in Seattle? To the Salvation Army? To ...? It is a very good question.
Having worked at a neighborhood food program at our church for a number of years, I know darned well that many of these people are running scams like you wouldn't believe.
