I agree with in niche1. Even though I didn't worked in exactly what might be called a psychiatric facility, but it more of a "daycare center" for the mentally ill. We had to deal with the socialpaths, delusional, child molestors, mentally ill, and anger proned individuals that was somehow deem "less dangerous" to society than the ones niche1 dealt with in a 24/7 psychiatric facility. Some of these guys have to take 16 or more pills a day, and we had to make sure they take them throughout the day. They were constantly disregarding of rules, fighting, and a couple of them was caught bringing knives. The guards or staff were not allowed to have weapons or arm themselves.

I once got into a situation with a violent individual that did not take his medication, was high on "street drugs" and was starting trouble with a female staff member. I had to pin him down until my female co-worker called the guards.
