This will just train bullies to pick on their fellow students in the bathrooms, locker rooms, etc. where no cameras are present, not actually fix the problem.
I have actually read about a camera system for locker rooms that would use image recognition to blur nakedness. Another system blurred everything other than faces and the static background. We are far from being OK with such things in schools, but they are out there for more secure areas.
One of the most obvious causes of suicide is newspaper reporting on other suicides. The reporting is allowed anyway.
I hope your never in a position of power over youth or vulnerable people, as your mindset could cause severe harm to people undeserving of such treatment.
