Unfortunately you just keep addressing a strawman, he's already said numerous times that that's not what he was suggesting, yet you keep arguing against it. If every parent in a classroom of students signs a waiver that their child's class can be recorded and viewed in a secure manner, only by other parent's of children in that same class, there is no restriction on movement or anything else. Most parents won't sign such a waiver will be your next argument. Say we have a 50/50 split of parents willing and unwilling. Children of willing parents are put together in a classroom and children of unwilling parents are put in another classroom, the first is recorded, the second is not. As I've said from the beginning, you are all arguing logistics, nothing else. You have sighted the privacy of the students, but if the parents sign permission for their children to be recorded in class for the purpose of approved guardians to review, then there is no issue. You could put cameras in a classroom over night, and the students would never even know they were there, especially younger children. The logistics could be figured out given a team of innovative and smart people working to address every issue, there's always a way to accomplish something.
