Boot Camp.

What he did was HORRIBLE and damaging to the 11yo girl he did that to! She 11 for Christ sakes.

I dont mean to be "insensitive" about your son - but mental illness or no mental illness, it boils down to wrong. He knew what he was doing and was aware of it.

Taking way his electronics isnt going to help. He needs Boot Camp to fix him up.

Also, dont give him everything - He cant have everything the world he wants. Until he learns that his actions will have consequences, you need to reinforce that. And get rid of the computer. Its not helping. Parental blocks are easy to bypass and dont work. Get rid of the thing or lock it up in your room. Its time to lay down some tough love.
