I don't think it's a location thing, it's an intelligence thing - I'm in Florida and it doesn't make any more sense to me

I was in a high school that received this active shooter campus wide recognition system. It included a few physical security systems to help autonomously alert if there were gun shots fired somewhere. One of the systems was these green lights inside the normal flourecent lights. They would turn red or flash or something as a visual alert. But the green light cast this weird green glow everywhere in the school and to me it was this eerie constant reminder of the threat. I was only a visitor for a special program for a few days, but even this was a little traumatizing for me. The drone would be terrifying.
