Former SWAT negotiator talks about dealing with Dallas police ambush shooter Micah Johnson

Five years ago, as a nation reeled from the deaths of two high-profile police shootings, the city of Dallas joined in protest. Activists walked through the streets of downtown, as officers patrolled nearby to keep the crowds safe.
But that night of peaceful protest was shattered when a Micah Johnson opened fire, ambushing and targeting the officers. Five were killed.
Dallas Police Department Sgt. Larry Gordon was the SWAT negotiator who tried to talk Johnson into giving up. For the first time ever, you'll hear Johnson's voice and the inside story of how his night of terror was finally stopped.
