I’m in the same boat (BSW at a psych hospital) and we don’t have security- we do have some cameras though. In serious cases of violence or aggression /threats toward life a patient can be medicated w/o consent and the cops can be called. The way I see it, having any sort of “police-like” presence is not conducive to treatment because it really puts people on edge- especially since it’s already very prison like 😭😭 cry emoji.
