On April 2, 2015, 43-year-old African-American Eric Courtney Harris was fatally shot during an undercover sting in Tulsa, Oklahoma, as Harris ran from authorities unarmed. While Harris was being subdued, Tulsa County Reserve Deputy Robert Charles Bates, 73, claims he confused his personal weapon, a Smith & Wesson .357 revolver, for a Model X26 Taser. Bates shot Harris in the back when he was on the ground. According to the Tulsa County Sheriff's office, he immediately said afterwards, "Oh, I shot him! I'm sorry." Bates was found guilty of second-degree manslaughter and sentenced to four years in prison, and was released after serving 18 months.
