Is there more footage than shown or did the reporter cherry pick? I think I know the answer. They only showed the kid spinning in place standing up slowly. My oldest son has always done that and even sometimes does and he's in middle school (never outgrew it). He's not autistic but is ADHD. When he twirls it's controlled and in no danger. There had to be more, otherwise it was an over reaction.
That woman that works there also appeared really wound up. She was probably getting teamed up on because it said another family jumped in.
