In my country Asperger doesn't exist anymore, they call it traits from the spectrum of autism or something similar. It has my interest because I have a few family members who were diagnosed with Aspergers (in the time that was still possible). My personal experience with them is that they seemed to be incapable of violence, violent behavior. Never, not even once, in over 30 years have I ever seen one of them act violently. With the youngest, my biggest concern was his inability to defend himself from others, not the other way around. When JR describes Burke's behavior, the example of the Lego set, I recognize it from my own experiences and realise it could just as easily be true.
