Maybe just using signal jammers in each classroom would suffice. But then the teachers are out of luck as well.
Are those legal? In the Netherlands they're not, I believe, because it would suck to have a shooting or a seizure and not be able to call the police/ambulance/superheroes
Well if the head honcho had an on/off switch,that would work,or an old fashioned land line.
But all the horror films I've seen start with the landlines being cut so that's not going to help.
And I got curious and apparently they're illegal in the whole EU
