It was after midnight at the Mile High Spirits bar near downtown Denver, and things were going well for the man in the middle of the dance floor. Patrons surrounded him and women smiled at him, some with their phones out, as he showed off his freestyle dance moves.
Then, he swung his arms back and squatted, as if to prepare for his next big move. He jumped up, arching his back and swinging his arms above his head. But as he was about to land his backflip, a gun flew out from his holster at the back of his pants.
