(nb. the vast majority of school shootings you'll see in the statistics aren't the sort where kids having phones matters, they're e.g. targeted attacks on a single person, gang- or otherwise crime-related targeted attacks, violence that just by happenstance takes place on school grounds outside and perhaps not even involving any students or staff; all of which tend to be over almost as fast as they start and aren't an ongoing threat to bystanders once they're over, and even those aren't terribly likely to be something a kid is present for during their school career, on average)
