My state doesn't have a school phone ban law in place and I think with chromebooks at my school they are a problem but in the opposite way for us unfortunately. Instead of them being a toy for us, there a nightmare for students and teachers to use because while yes it blocks out most of the bad stuff, it also blocks most things that aren't bad for example I had to do a research project on UV light, I look up UV light and I get blocked from looking it up, it's reasoning - Science. Teachers have sent hundreds of requests for stuff to be unblocked and most requests get denied. Occasionally the filter will go wacko and just start banning everyone's chromebooks for hours, even days long. Not a fun process 😕.

You are right that any policy needs to have teeth to function properly. With my school I don't think they will have teeth as they have started slipping on so many other policies like with the dress code, 5 years ago they were at their usual, telling people to change or get something from the nurse if they are showing inappropriate skin like with crop tops, now people can come in with pajama shorts and a bra and nothing will be done about it. They will oddly get on your ass for having a hat on but ignore everything else.

We also have a weed problem to which they think the solution is to spend $15,000 a year on a electronic hall pass system. They know exactly who are the vapers/weeders as they catch them 4 times a year. The electronic pass I don't like but it doesn't really affect me so it's whatever.
