The Army has opened an investigation into Dallas sniper Micah Johnson’s military service. One week ago, Army veteran Micah Johnson shot and killed five police officers at the end of an anti-police brutality march. At least seven officers were also wounded in the attack. In 2014, a female soldier filed a sexual harassment claim against Johnson while he was serving in Afghanistan. She also requested and won the military equivalent of a restraining order for her and her family, and she recommended to the Army that Johnson receive mental health treatment. The Army sent Johnson back to the United States and recommended an other-than-honorable discharge. The Army is now investigating why Johnson received an honorable discharge, despite the Army’s own recommendation. Dallas Police Chief David Brown has said Johnson was planning a significantly larger attack, based on the bomb-making materials and journal found at Johnson’s home in Mesquite, just outside Dallas.
