Police just released video footage of real-life hero stopping an armed robber at an Illinois bank in January, and gun controllers are not going to like it.

Brian Harrison, a former deputy, was working as an armed security guard at Alpine Bank in Rockford, Illinois when Laurence Turner walked in wearing a blue ski mask and brandishing a gun. Turner, who officials say was high on drugs, fired once into the ceiling before turning his weapon on Harrison.

Harrison’s quick reaction saved his own life as well as those of others in the bank. Within 15 seconds, Harrison stopped the drug-addled thief dead in his tracks.

“There is no doubt in my mind the actions of Brian Harrison saved the lives of those that were employees in the Alpine Bank location on that date and saved his own life,” Winnebago County State’s Attorney Joe Bruscato said, according to 23 WIFR.
