“ The Broward County School Board told WSVN that all district protocols had been properly followed.”

I’m no expert on this, but it appears that their protocols may be inadequate.

Parents need to be investigated, something is screwy

Has there been any investigations on the child's home life?

Early childhood behavioral intervention is something I'm very familiar with, as the mother of two special needs boys. However, this is a very special case. If this child is showing signs of sociopathy, he needs to be in a very structured program with only positive intervention for good behavior. That's the only thing that works, apparently. Of course, there may be other reasons for his acting out. I have observed many classrooms with autistic children, for instance, and this type of behavior would be extremely rare there, unless the child were having a melt down. Even then, they would not attack a teacher unless their space were invaded, or they were overwhelmed in a major way.
