What happened? On Nov. 11, 2018, a little after 4 a.m., a police officer responding to a report of gunfire at a suburban bar shot and killed 26-year-old Jemel Roberson, a security guard at that bar. Roberson had just captured a man with a gun following a shooting at the bar, which is why police were called.

When police arrived on the scene, Roberson was outside the bar, holding one of the suspects in the shooting on the ground with his knee in the man’s back and his gun pointed at the man’s back. According to a spokesperson for the Cook County Sheriff’s Office, Roberson was licensed to carry a firearm. He was in uniform and was wearing a hat with the word “Security” on the front. The officer shot Roberson even though many people around were screaming at him that Roberson was a security guard.
