At 5:45am on October 21, an ex-con named Benjamin Frazier was trying to get into Drai’s After Hours club inside Bally’s Hotel and Casino. He reportedly objected to the $30 cover charge, and allegedly pulled out a gun and shot two security guards. He then walked through the lobby of the club, pistol in hand, seemingly ready to shoot again.

Kenneth “KD” Brown, a comic from Los Angeles living in Vegas, tackled the gunman before he could do any more damage. During the scuffle, Brown was shot in the neck and chest. He died on the floor of the lobby. The two security guards survived.

The video of the event was just released, and since Vegas has some of the most sophisticated surveillance systems in the world, the footage is disturbingly clear. Frazier’s lawyer is using the blackout defense, claiming his client remembers nothing of the shooting.
