I see patients under the influence of bath salts every now and then, but none of them have been violent -just very hysterical or paranoid. Seeing one do something like this actually frightens me.
One guy around here got high on them, stole a school bus, then drove it into the store it was parked in front of. After his arrest he was committed to a mental hospital that he later escaped from. He was apprehended a few days later.
