There are mush more restrictive laws on the books right now in every state that allow the “authorities” to take a person into custody for 48-72 hours for mental evaluation IF it is determined that they are an “imminent” threat to themselves and/or others.
Also, people may be taken and quarantined indefinitely IF it is determined they have a dangerous, communicable disease.
Grow up
Oh. Arbitrarily locking people up because some relative or shrink “thinks” they are dangerous, without due process is a good thing, eh?
