In a documentary on the "Roaring 20's", since a high percentage of people in speakeasys were armed, and you never knew who was carrying or what they were carrying, it was better to be polite and apologize for any verbal or physical faux pas.
The solution is simple! Just make the whole city a “gun free zone”, then the criminals will have to pack up and move somewhere else, right?
Which happens every single place where people are armed. Dodge City in the 1870’s was a “gun free zone” with strict laws against carrying in the city limits. And guess where all the stories of gunfights and murders came from in the old west.

And yet there are liberal websites telling how wonderful and commonsensical this was, I guess because of how well it worked.
