We definitely need protections for people who are institutionalized. But we also need protection from the members of society who are being victimized by mentally unstable individuals. Many large cities seem to have no interest at all in the latter, to the point where there’s a class of unwell citizens that the laws no longer apply to. Many are threatening people daily, violently assaulting people, committing frequent theft, using the streets as a bathroom, etc., mostly with impunity, and law-abiding citizens are told to just live with it.
