One time a cop I know had to fight a guy on an LSD trip. He ran into a public park, grabbed a three-year-old and tried to drag it away. The mom freaked out, other people called 911. The cop said the skinny little kid had the strength of 10 men, and somehow the fight wound up inside the police car. He said the weirdest thing is that the entire time he was yelling out colors, blue!! red! yellow!! green! Eventually he was able to get him handcuffed through the steering wheel.
Later, at the hospital, when the kid was back to his senses. He said he had believed the three-year-old was his younger brother and was trying to take him home. He thought the mother was trying to steal his little brother from him.
Spooky drug.
Actually, that sounds more like PCP. A friend told me.
