Yep.... you can watch videos every day of 11 and 12 years old assaulting other young people and even little kids. It just is what it is.
When mentally ill, mentally handicapped, and behaviorally dysregulated children are mainstreamed into classrooms, this is what happens. There is a reason that our forefathers had separate schools for them. They disrupt and are at times dangerous, and at other times, are abused.
They need protection and management.
