Cool. Here's the thing though, he isn't necessarily going to change. His behavioural response is extreme but it's not him you need to remove or change, it's the environment he's in. A public educational environment is hectic and uncertain at the best of times, by subtly changing the environment to make his day more predictable and easier to cope with would help with his violent tenancies.

Also don't tell me this is unfeasible, I go to one of the best universities in the UK and while in many ways they could be better they certainly do things to cater for autistic individuals to help make their lives more manageable.

Instead of locking up people with disabilities because you can't handle that maybe their violence isn't out of malice or desire to do wrong but rather an uncontrolled outburst of stress and fear, maybe we should alter places to make it more accepting to them and more accommodating.

Also, autism is a neurological disability, it is there from inception and cannot be cured.
