I’ve always wondered how people thought the “good guy with a gun” would work in a chaotic real world situation. Suppose you’re armed and there’s a mass shooting event. You pull out your gun and keep a look out for the shooter as you hear gunfire getting closer. Then you spot a guy holding a gun. You quickly take aim and fire…
… And hit another “good guy with a gun” who was trying to take out the mass shooter the same as you.
Oh, but then you get shot by a third “good guy with a gun” who thought YOU were the mass shooter.
Arming everyone and telling them to be “good guys with guns” just seems, at best, like it would lead to MORE injuries and deaths.
