These are all people I ran across in Las Vegas years ago.
I saw a guy take off his clothes in front of a store, run inside, and then he crashed through a plate glass window, and cut the hell out of himself, trying to get away from the store security, and the cops when they arrived. He went ballistic after the manager of the store told him he would have to stop trying to sell copies of some whacky religion book in front of the store. He had to have hundreds of stitches. I had to testify in court weeks later, after he had healed up. He ended up pleading guilty, then losing control in court when the judge ordered a psych exam. He really screamed great.
The McDonalds I worked across the street from was a known "Moonie Place" Managed by, and most of the employees were Unification Church members, and well, were downright peculiar. One girl would run across 4 lanes of traffic every day when she got off work, without looking at all. We started making bets with each other, "Ok, today, she gets it!" "Nope, not today!" The bet was for a buck, and it was mostly a joke, but we knew it was going to happen, sooner or later. One day, I said, "Today is it, I can feel it!" She comes out, and makes it across two lanes, but a green Camaro hits her, Luckily, she mostly gets hit by the windshield and is just missed by the car following behind. The first thing she says is, "Call the Unification Church!" She tried several times to get up, but we wouldn't let her. She finally did let them take her to the hospital. My ex-GF worked with her, and told me she tried to come to work the next day, with a broken wrist, but the manager sent her home. She went right back to running across the street again as soon as she was able to run. My GF said she told her that god wouldn't let her die from getting hit by a car before she met the Reverend Moon. Sheesh.
A guy that used to come into the hotel I worked at seemed to be a normal guy, but then began acting strangely. He comes in one morning, and then went to the bar, ordered a drink, and said some crazy stuff to the bartender about how he's being "persecuted". The bartender asks why, and he shouts, "Don't play stupid, you are part of the group trying to destroy me!", and then slammed the glass down on the bar, and pieces go flying everywhere. We (security) get called, and end up fighting with him for a while, then he just gives up, and we trespass him and send him on his way. About an hour later, one of the change girls comes up and tells me to look out the door. The guy is across the street, naked, and shouting about something. We call 911 and the fun begins. He does a pretty good job resisting arrest at first, but eventually, he gets cuffed and hogtied. In the paper, it says he got a 90 day psych evaluation. About a year later, he's inside and I toss him out. He's a full fledged street person at that point, and is totally out of it. He fights a little and then calms down. We just put him out the back door, and he seems to leave. About an hour later, he's at one of the front doors, naked, and trying to come back in. I try to be reasonable with him, but he gets all wound up, and I tell him to leave or the cops will deal with him. He starts yelling at the top of his lungs about the CIA and other stuff, and puts his hand through the front window. He screams about how his blood will cleanse him of his sins, and there's all kinds of it, spraying out of the sliced up artery in his arm. The cops suddenly arrive, and by the time he stops fighting, he and the cops are totally covered in blood. He was giggling away when they put him into the ambulance.
