The video above was shot by Madeleine Herman, wife of UFC fighter Dave Herman, and it shows the fighter getting tased by cops at a gas station after exiting his car during a traffic stop.
According to Madeleine, the cops started following the couple after they began experiencing car troubles and were looking for a place to pull over. They eventually pulled into a gas station, at which point Dave got out of the car, walked toward the cops, and asked them to show him their IDs. The cops did not take too kindly to this, and ended up hitting Dave with a taser—a lethal weapon that's killed hundreds of Americans.
Madeleine's video was uploaded to TheFreedomline.com, a website run by Adam Kokesh, an Iraq War veteran and libertarian activist.
