You know, if I were to take out my gun in such a scenario, that would be a risk I would be willing to take.

If you get instruction from police officers, as I did for my Missouri concealed carry license, they'll chill you with stories about they, or someone they know, almost shot a fellow officer. It's something everyone is concerned about, shooting a good guy.

In these sorts of scenarios, it's thought to be relatively easy to figure out who's a good guy and who's a bad guy. Which armed person is everyone running away from, or if downed, facing away from. In your scenerio, where it sounds like the shooter has been downed, is anyone still shooting? Etc.

Do you even know any "gun nuts"???
