The kid’s mom should report every single teacher & administrator who brings a “deadly” motor vehicle onto the campus. After all, those kill tens of thousands every year while imaginary grenades kill zero.
Another case where people need to wait for the full story.
Turns out the mom is a serial publicity hound and liar.
Reminds me of the big stink on FR several years ago about a school in Palatine, IL. Kid gets suspended from school for “having NRA materials” in his locker.
Turns out that the mom made it all up and the materials in question was a hit list of students and teachers the kid said he wanted to kill.
