I spent 28 years teaching/counseling dysfunctional adolescents in probation facilities, residential treatment centers and public schools and find this story hugely disturbing. 

About 30 years ago I had an OpEd published in the RG, then the NYT addressing this very issue.  It was titled "Creating Monsters" and focused on the need for early and consistent intervention when students' behavior interrupts the classroom and, especially, threatens the safety of other students and the staff.  At the risk of sounding a bit presumptuous, I suggest the 4J administrators need to read it.  The "culture of chaos" described in this story CANNOT be tolerated.  Gary Crum
