Maybe except for you spelling teacher. ;)
Public school administrators like to brag that they have cameras in every hallway, on buses, all over the place. What these administrators have to realize is that parents and students will respond in kind — sort of like a “Spy vs. Spy” situation if they are unhappy with a student’s treatment.
We now have a case in my state that is similar to this one, and it involves a special ed teacher and a student wearing a recording device.
