Of course it should be used, to protect pupils and school. Besides, it's a way of controling students so that they can't do wrong things...
Should Surveillance Cameras Be Used In Schools?
Yes because what if some violence is going on that way you know who and who was involved
Unfortunately with all the weapons & violence becoming common in schools I think it would be a good idea. It would be as much for the students protection as the schools. As with all public places they should not be installed in bathrooms but I would vote for cameras in schools if it protected my child.
