If you’re high on drugs, yelling scary stuff, acting violently without technically doing anything illegal. and threatening to kill yourself, I’d restrain you myself if I could. What’s the alternative to locking you up or waiting until you hurt someone & shooting you dead? You’re out of your mind, ruining everyone’s day, and you need a timeout to get your shit together, so if you wanna act like a child with no regard for the well-being of those around you, I’d have zero problems with sending you to your room until you cool down. It just so happens your room is a padded cell at the local mental health facility.
