Nancy, I've also seen my son enraged and delusional IMO, and would have bet the farm he was on acid or something, and we've tested him on the spot and it only came up positive for THC. But that guy in FL stripped naked, flug himself around a light pole, had superhuman strength to chew someone's face off, was warned by the police to stop, but didn't, and had to be shot to death. She may be covering up for something, but his fiancee said he was quiet, religious, never in any trouble. I am sure that's true in HER perspective, but this guy must've been totally messed up. I'll bet they're getting ready to sue the police for excessive force.
The bath salts would have tied it up into a neat package, like you see on Law and Order, or CSI. This is just whacked out. I remember when I used to take the NYC subway to work in the late '70's, early '80's and it was like crazy town. There was just no describing it, and it was like being on a tour of Vietnam every day for 45 min. each way. I fully expected, and would not have been surprised if someone threw a live grenade in the subway car just because they could. If you didn't get PTSD from that, you wouldn't get it from anything. There were so many mental patients roaming around, you were assaulted by "entertainers" on the cars who would shake you down for money, hare krishnas, angry radical "religious" nuts, 3-card monte sharks, gold snatchers, people who would push people in front of oncoming trains, etc.!
But this guy in FL? How does a human being become so radically deranged, seemingly overnight? There's got to be more to the story. Otherwise, my faith in mankind is lost!
