Oh...this is so heartbreaking and shocking. I only watched the first 10 minutes but that was enough. I've worked with kids who have Autism and I've never seen anything like this before. The teacher and aides need to be fired and never allowed in a classroom again. And the school district needs to look into their hiring practices for aides and special ed teachers. The teacher needed to be responsible for her classroom and she should have known what was going on. No excuse for this kind of behavior.
