There are some violent autistic people or ones that have violent fantasies. We have an autistic person in our extended family and he has told us about other autistics he has met that are violent or talk violent. Just talked to him at Thanksgiving.
She was supposedly very high functioning. She mostly cleaned, some easy filing and other repetitive tasks. Though, I can't say I believe she really belonged in a workplace. She had a caseworker that came and saw her once a week at work, once a week at home and she had state funded transportation to and from the office. I am sure the owner got some sort of break for having her there. In the end, I'd bet having her there cost the taxpayers quite a bit but it made the liberals feel good and gave the caseworkers and transportation companies jobs.
