So what you're proposing, not very clearly at all, is that a parent make a request to say I want to watch video from 10-11 on this day of this teacher. Then they have to report to the school to see a prepared video of that, in a special secure room during school hours, for which someone has blurred out the faces and responses of all the children with a Special Ed dx, an IEP, a 505 and custodial restrictions. In every single classroom in American right now, that's AT LEAST three children per class of about 20 kids. That's a lowball estimate. Could be half.
Well, you're getting better not demanding a live feed. But who's going to do all that video work for the nutso cuckoo parents who would do that all the time? ETA: Let's not pretend all the parents are saints here. Look around at the general population. Nutso teachers and nutso parents. Yep.
(Of course since the last time you stepped in an elementary school was 1975, you have no idea what an IEP or a 505 is.)
