Yes Bob, lack of adequate staffing at schools is probably the single biggest contributing factor for student alienation.

Infact, social media (which has a lot to do with cameras and technology) is often a factor in alienation and bullying.

So I agree, cameras everywhere is not a viable solution. After all, someone would need to view and review those videos! And then what? Punish the bullies, leading them deeper into conflict with the school system?
