Is it time to start designing schools so that the buildings are basically faraday cages that block all cell signals? And definitely no Wi-Fi. Yea I know parents might cry “I need to be in contact with my child at ALL times”. But no you don’t and in the public education system you shouldn’t even have a choice, if you need something call the school someone will pick up on a landline and deliver your message. And if there’s a school shooting oh well if your kid dies they die so hug them tightly every morning like it’s the last. Otherwise I just don’t see any way out of this problem.
