The whole scene was a production for the video. A copycat of the rap star beating videos on the internet. I would say conspiring to do that makes them severely emotionally disturbed. Continuation school or whatever they call it there is well deserved.
Emotionally disturberbed under FAPE legislation is a huge umbrella rangeing from severe psychosis to something as minor as facial tics. There lays the problem, under FAPE they do qualify. Unfortunately school districts only ship out the worst case scenerios due to space constraints. The program in my area has a waiting list. So these kids will be put with the most severe. My favorite pediatrician told me that kids like these, loud mouth brats, usually come out with worse behaviors. I have ton of anedoctal evidence to support this position. Sorry I see this a government overreach to the max. The parents did have some leverage but chose not to use it. Lousy parents.
