With all due respect, I think you need to do some research on autism. Because you just don't understand it.
Basically you are talking about Dustin Hoffman's Rain Man being a serial killer. Sorry, not believable.
I've lived with autism for close to 60 years now, and know several others with it in addition to those in my immediate family. Life isn't like the movies, and every person with autism is not Dustin Hoffman. In fact, I'd be willing to bet that very few are like what's portrayed in the movie. I'd suggest reading up on the autism spectrum, and you might be surprised by the wide separation between high spectrum and low spectrum, between those who were diagnosed early and those who were diagnosed as adults, those who received proper treatment and those who didn't, etc.
In addition to the time spent with my son, I have talked to many therapists about it, seen doctors at the autism society, heard lecturers about it, and read many, many books. Asperger's Syndrome was basically unheard of in the US until the early '90s, and I had read up on it years before his psychologist had even heard of it. In all of my research, discussions, experiences, I have never had a professional say, "People with Autism don't commit crimes; that would be like saying Rain Man was a murderer."
I personally don't have Asperger's, but my doctors have told me that (in spite of not exhibiting all signs of it) I would most likely fit the criteria for high-functioning autism. Some people with it self-medicate with alcohol and/or drugs. I chose a different way. As a teen, I bought books on reading body language and facial expressions, I practiced looking people in the eye by using a mirror (and it still took several months before I succeeded with the mirror for the first time), I read hundreds of self-help books, talked to therapists, got treatment for my anxiety and depression, joined a Toastmistresses group to learn to speak to people, used a tape recorder to help me monitor my voice well enough to be heard from more than 6 inches away, etc., etc., etc.
It took a lot of work and a lot of years, but nobody meets me now and thinks, "Wow, she must be autistic or something." I've had many people tell me how lucky I am that speaking to people comes so easily for me, and it takes a lot of effort to just say thank you rather than cracking up laughing. Funny thing is, the harder I work at it, the luckier I get! Anyway, to make a long story even longer... If you have done more research on it than I have, and you have evidence that I really don't understand it, I'll be more than happy to hear what you have to offer too. As my father always said, "You learn more from listening than you do from talking."
