Wow. For some reason I didn't see this until today. I'm a little old lady, but I'm a retired teacher, and I note a trait that teachers have is that they intervene. I don't know how to fight, and I would probably, make that probably/definitely wouldn't approach someone with a gun, but I do know I'd stick my nose in what looks like an assault to me. How do I know? I've done it before. Perhaps I shouldn't expect it, but I hope that if someone saw me getting assaulted that they'd jump in.
