In defence and having an Autistic daughter, may I just say that they have obsessions and many are very intelligent. I just feel sorry for him, in as much as nobody was controlling his obsession.

I doubt if he is dangeous as such, but by god how he managed to do what he did defies logic. Just how secure were things.

Just trying to look at it from an autistic persons point of view.

Most people do not understand their behaviour. Much is the pity.

OK I have my anti missile shield attached :-)
