A police car drives into the Springlake Police Station in Oklahoma City, on Oct. 7, 2015. Former Oklahoma City police officer Daniel Holtzclaw, who worked in the department's Springlake Division, is accused of sexual offenses against 13 women he encountered while on patrol. In an investigation of sexual misconduct by U.S. law enforcement, The Associated Press uncovered about 1,000 officers who lost their badges in a six-year period for rape, sodomy and other sexual assault; sex crimes that included possession of child pornography; or sexual misconduct such as propositioning citizens or having consensual but prohibited on-duty intercourse.
