Or they couldn't.Because they could.
Consider an active shooter situation. For the average citizen, approaching a scene where something is going on, they will likely take time to figure out what is going on. It's chaotic. People are screaming. Say I'm armed. By the time I have figured out who the bad guy is and who the good guys are, the situation will have progressed. Suggesting that an armed citizen would have saved some lives is pure, bald *** speculation as grounded in reality as the worst of the YouTube martial artists inventing long, elaborate counters that look great on camera. It's fan fiction.
I think that firearms in a home are a TERRIFIC idea, if they are handled safely. The delineation in a home between the bad guy and the good guys is very clear. But in an active shooter situation such as the one above, I can see where an armed citizen might help. I don't, however, see how you can suggest that an armed citizen would help. Or even that it would be likely to help.
However, every time we see an active shooter situation like the one in this thread (which has little to do with poverty, class, gang violence or any of the other red herrings that come up), it's like clockwork. One side spins it to support gun control. The other side spins it to support essentially a gun free-for-all.
