My brother was hospitalized several times because of psychosis. While he didn't actually do any physical harm to us, he did threaten verbally, wave a knife and even grabbed me by the neck. In the small town my parents live in, a person I know also has delusional thoughts, he is now in jail for stabbing his father (while sleeping). Another kid in a nearby town stabbed his mother not long ago, also with mental problems. So, I don't know what my brother is capable of, but I don't think we really need to find out and I think he is grateful that nothing bad had happened during his several episodes. One note though, every hospitalization was voluntary. They gave him a form to sign and he did. I don't know if he understood what he was singing though, but tricking people into hospitalization is somehow better for respecting human rights than forcing it.
