NEW: Footage released showing a Tennessee security guard calmly taking down an attempted mass sh**ter in Chattanooga, Tennessee. A gunman had started firing at a group of people outside of the Dream nightclub when the guard jumped into action. The man who fired into the crowd was hit by the security guard before he could take any lives. Head of security Joe Reed thinks the attack was planned, revealing security footage of the 24-year-old suspect parking his car down the road before attacking. "It was quick action by our licensed security guard who did what he had to do to protect innocent lives," said Reed. The suspect was injured with non-life-threatening injuries.
