Earlier quoted context omitted.
Someone decided the person was insane to begin with. If we could trust them to lock them up we need to trust them to release them too. Now, this is a nearly non existent problem isn't it? For major crimes, being locked up in psychiatric care is a longer, or indefinite sentence, than would be served in prison (this varies between countries of course).
> If we could trust them to lock them up we need to trust them to release them too. This guy was getting locked up no matter what. The only question was, was he getting locked up in a prison or in a psych ward? So do we trust psychiatry enough to say "lock him up here rather than there"? Sure. Do we trust them enough to say "It's safe to release him now"? That's a harder question.
In the involuntary commitment case, is it reasonable to hold a person longer than what the equivalent prison sentence would be, even if the person is still considered mentally ill after the equivalent time?
