My guess is that the autistic kid was years behind—and so with younger children. No excuse, of course.
The 7 year old was the autistic kid! He could not speak and tell anyone he was being abused.
The 15 year old was normal from the youtube video I saw so what was he doing on the bus which we have to assume was the short bus.
Robe people have asked about the driver but most short buses have an aide for special needs kids. It’s the bus drivers job to drive the bus, keep his eyes on the road. If a kid yells or something then yes he should do something. However a child who is non verbal, there should have been an aide on that bus.
This was caught because there are not cameras on all school buses.
The way I read it the victim was the one who was the non-verbal autistic kid.
The victim was the autistic child, not the accused.
