We should probably solve the root cause, but the 2A death cult does a fabulous job keeping people convinced that MORE guns is the solution, completely ignoring damn near every statistic shows more guns lead to worse outcomes.
I don't understand how students having a phone helps in the case of school shootings. The school will call the police and any parents of students injured/killed will also be contacted by the school.
It doesn't (and likely hurts, by clogging cellular infrastructure and roadways).
But parents want to know ASAP so they can rush to the school and "help". Probably because police in the US aren't actually required to actively protect people. And have proven incapable of doing the job.
Yep, that's why "help" was in quotes - there's nothing a parent can do from the parking lot. And allowing them into the building probably doesn't help either. It's a shit situation for everybody involved (and better solved at the root - we're just unwilling to do that).
