Can you give me examples of crimes or situations that were thwarted by citizens carrying legal firearms?

I know the NRA publishes a few cases every month but I consider them right wingers bordering on extremists. And I don’t trust extremists of any type. I believe the truth is somewhere in between.

I’d like to know first-hand stories from you or a family member, not a friend of a friend of a cousin of a friend.

Here’s mine:
About forty years ago, my Dad worked as a broker selling candy and cigarettes to distributors that delivered to the many local small shops in NYC. He was licensed to carry in the City (not easy to get) and carried a .32 S&W revolver that was considered old even then. One day, while leaving a customer’s shop in broad daylight, some “youths” came from nowhere and blocked his path. They didn’t say anything. They just made it impossible for him to walk to his car. He opened his jacket and said “You don’t want to do that.” while flashing the gun in the holster. They fled. While unscathed, he was a wreck for weeks.
He would have been around 60 at the time and that convinced him it was time to retire.

There was no record of the “crime” because nothing happened. Police were not called. The incident will never be listed on the side of responsible citizens carrying guns. Yet until he died, my Dad believed that S&W saved him. (I still have it and even added it legally to my carry permit as a piece of family history. It will never be fired.)

I’m sure if this happened today, the ending would be different. He would either be shot, or charged with “Brandishing a weapon”. Either way, the “youths” would still be on the street.
