In the CCW class my wife took, the instructor said to avoid large public gatherings for just this reason. You will run out of bullets before they run out of thugs.
In other words, the State Fair is off limits.
I was taught the same thing in a very exclusive military gunfighting 101 course. The only problem with that thinking is: you surrender your liberties, and you allow evil to win. Insert Edmund Burke’s famous quote here.
Some things are worth putting it all on the line; and our Founding Fathers knew that intuitively.
And I’d love a story that ends with a group of white girls in capri pants and white-girl tennis shoes dropping a half dozen thugs, out for a night of wilding. But one can dream.
