Welcome to the K-12 Surveillance State
Since I can't read the article I can only go with story time here- my wife has cameras in her room and she loves them. Fights about 'who started it' are ended with the words, 'Ok, let's look at the video'. And when some little bully gets called on the carpet and their bullying parent comes in all set to steamroller administration with 'that's not what my child said happened why are you picking on them' the principal just rolls the footage and watches as the realization that their kid is a little shit dawns on the parent.
