This is an ethical question unlike any I've seen before.

I have some dealings with a guy who has either Asperger's or autism, with some associated intellectual deficits like basic arithmetic. (I can't pretend to like him one little bit). He has really fucked-up perceptions of what other people perceive and want - almost zero "theory of mind".

And he's doing jury service, in a trial that's been going on for a long time and must be very serious. With so little understanding of even normal people in normal situations, what chance is there he'll have any clue about the extremes involved in a major crime?

This seems to me to be a situation where "just give them the right to be themselves" doesn't work at all. His interpersonal incompetence has to be fucking up somebody else's rights.
