They were searching backpacks and lockers in my high school back in the 90’s, student privacy has been dead for a long time. And at the same time they let students keep rifles in their cars on school grounds during hunting season so those students could hunt before school. There’s no real logic at work, just school boards reacting.
Seems like the cops should now be worried about civilian phones exploding and now might consider shooting anyone that tries to hand them a phone /s
