"During active shooter drill, four teachers at a time were taken into a room, told to crouch down and were shot execution style with some sort of projectiles - resulting in injuries to the extent that welts appeared, and blood was drawn. ... The Indiana State Teachers Association is lobbying lawmakers to add language prohibiting teachers from being shot with any sort of ammunition to a school safety bill working its way through the Statehouse."

I feel like existing laws should cover this. If they need a new law so specific to this situation, I'd worry there's nothing covering many other situations.

Can they press charges for assault? That'd send a clear message.
