Pediphiles wouldn’t have any greater access than they already do. Honest parents would have a change to identify bullies and have them dealt with. Small issues with would generally be irrelevant after a short period. Obviously it wouldn’t be perfect but it would improve education in the long haul. Those who play up to cameras would learn to stop when their parents start paying fines for disrupting the educational process.
And what about observing pedophiles who are the teachers. Might get an early warning sign about teachers who have more than an educational interest in youngsters.
You don't know much about the public school system in this country, do you? Parents being made to pay fines? Yeah, right!
