This technology seems like something that should not exist in the first place. Why do schools feel the need to spy on the students? Who cares if a student swears in a chat message. Spying on all students should not be considered acceptable, when waiting for an aggrieved party to bring up the issue to staff is a possibility. Administrators have always been especially power hungry in my experience in schools, so this isn't surprising. But there should be legislation banning this. Breaking open student lockers to read their journals would be considered unacceptable, why is this? Lower Merion v Wolk where the school was taking photos through laptop cameras and had to pay a large sum of money, is something I hope happens to every school that uses this.
