If people can use Asperger as an excuse for killing someone, then people with that disorder should be kept out of school in order to protect our children. Apparently, it would also reduce bullying in the schools which is also a good thing.
So the answer to bullying is to remove all the potential victims from school? Bullies will always find someone weaker. Bullies are the ones who need to be removed or controlled; as the psychologist says, Asperger's people are usually less violent than average. Many bullies are junior sociopaths and future violent criminals. The growing incidence of bullying in schools is a severe problem, which hurts many children. Don't engage in "blaming the victim."
