Here we go again. A young male, picked on by others in school, takes a gun to school to get "even" with those who took exception to his type of diversity.
Maybe the "bullies" should be thrown out of school? Nope, can't do that, because they have social disabilities, have rights and must be kept in school. Maybe the victims of the "bullies" should be thrown out of school? Nope, can't do that because that would empower the "bullies," segregate the "bullies'" victims and cause the victims to feel bad about themselves.
Drugs: let's put all the school kids on drugs and they won't even know what's going on in their lives, never mind whose doing what to whom. This must be the answer. You can't remove the "bullies," for being disabled, they have rights. You can't segregate the potential victims of the "bullies," for it would increase the disabilities of the "bullies." Like one of the students said when interviewed, "everyone gets picked on."
