Reportedly (and unsurprisingly) this CCTV footage is out of Brazil and documents what is likely an off-duty police officer thwarting an armed robbery by shooting his attackers with his concealed handgun.

The criminals roll up quickly in a sedan using speed and surprise to overwhelm their intended victims. They move in and start shaking the men down for their money and valuables. The man on the right is able to draw his weapon and fire into the two closest attackers, dropping one instantly. The second man is hit but retreats rapidly. He fires at the third who appears to lurch in a manner indicating a possible gunshot wound. The threat is neutralized. Bad guys lose, good guys win.
