Have you ever dealt with an autistic child? You might be astounded at what they can do when they go on a "rampage".
If an adult can't subdue an 8 year old without using handcuffs or drugs, they aren't much of an adult... At age 6, I could lift a standing 220 pound person off the floor, and at age 7, I took the paddle away from a teacher and hit her back with it (mistake). There's obviously a wide range of 8 year olds, and teachers in physical capability.
