yes, Narky, it is possible.
as everyone on this thread has agreed. and there is also agreement that what he did was abhorrent, and there is no suggestion he should go uncorrected.
but, from knowledge I have on how people with spectrum disorders are treated, both in daily life and in dealings with the police - I find it highly unlikely that his As was taken into account in the way it shoudl have been. It is far more likely that just about eveyone who had dealings with him has thought the same way as the majority on this thread, namely:
As does not mean unkind
AS does not mean unintelligent
He must have understood what he was doing as he had done it beofre
My brother/child/I have AS and I do not do this, therefore he must just be a shit to do this.
and so on.
There is no precedent for how to deal with this. and there is almost certainly no policy for how to deal with this man, and others in similar situations, and how to even begin to start educating him. he will most likely have been failed throughout his life (otherwise why is he living alone, drinking most of the day and not understanding social norms to the degree that he is doign what he did?), and will continue to be failed.
while those around him clutch their skirts in horror at what "those people" can do, and the general public specualte that "AS is not an excuse, he knew what he was doing", all the hwile demonising and belittling a very debilitating (to some) disorder.
