I work in schools. I'm cautious about making sure side doors close behind me. That's about the extent of my shooting concerns. I've recently been complaining to security at campuses about lack of or poor fencing around playgrounds. I'm more concerned about strangers entering, kids running out, and stray dogs than shooters. Millions spent on door fobs, tracking systems, and bulletproof glass, but you can't fix a kid-sized hole in a fence? They told me the state mandated the other things; fences aren't required so the state doesn't help fund. They didn't jump on my offer of $100 and a shovel.
