There's more to this horror story.
Schizophrenia is awful. The medications for it are awful. Once someone is "the system" for violent schizophrenia, there's a really good chance that their lives will only only get worse. A remarkable number of schizophrenics are not helped by "the system", they're mainly sequestered away and given drugs that reduce their outward symptoms.
It's not just awful, it's effing awful. On top of that is the delusion aspect, which aggravates the personal horror the person might find themselves in. Schizophrenics still have emotions, feelings, and loved ones, and then are forced to watch people disregard their feelings and watch themselves lose their loved ones as their families becoming increasing disconcerted by the madness.
It's 1% of people that get this disease, and a horrid number aren't helped by the medication "system". 1%. That's a lot of social pain. Even worse, Big Pharma has given up, they don't research it anymore. It's only government funding and charity funding that supports research; and when's the last time you've known anyone to give to a schizophrenia charity?
The modern system is not sufficient, at all, but it's "out of sight, out of mind" because everyone figures that "the system" is handling it and thus no one feels the urge to be pro-active.
