Yes, and if we could round them all up and put them back in institutions today, society would be a much better place. Plus, they can get treatment and care that they cannot get on their own.
What gets me is the mentally ill were de-institutionalized for “humane” reasons because the mental hospitals were not well run and abused some patients. But the living conditions in the asylums, as bad as they were, were a million times better than what the mentally ill endure on the streets. And, on the streets, the crazies ruin all of society.
