should schools be wired with video cameras?

I ran across a story about a father that wired his son to document what teachers did at school. This situation is so sad. This is a good video to watch so you can be aware of situations like this. Here is the Facebook Page.

The father was interviewed and has vowed to help schools make changes and get some teachers removed. Here's the interview 
And a video response from an older boy with autism who talks about this and asks do we need to have cameras in the classroom to monitor schools?
What do you think?
