My Autistic son attends a mainstream high school, he's 13 with the mind of a naive pre-teen. For this reason, we monitor closely the content of the apps he accesses, the films he watches and he's also not allowed to walk to/from school because of his vulnerability.
He has just informed me that in his drama class, they've watched a film and he can't get the visions out of his head. The film was a 1991 title "Let him have it" - a crime/drama with an age of 15 on it. It shows in detail (apparently - I've not watched it myself) a man being hung.
This isn't something I'd allow him to watch at home, because of the age on it but also because of the detailed images of someone dying/being killed! The children in his class are all 13/14, would this be something you'd be happy for your child to watch at that age, without your knowledge or consent??
