President Obama is speaking in Dallas, Texas, today at a memorial service for the five Dallas police officers killed by a sniper Thursday evening. Former President George W. Bush is also slated to speak at today’s memorial service. The shooter, Micah Xavier Johnson, opened fire at the end of an anti-police brutality march, killing five officers and wounding at least seven more. Johnson was an Army veteran who served in Afghanistan in 2014. While on tour in Afghanistan, a female soldier accused him of sexual harassment, took out a restraining order against him, and he was sent back to the U.S. by the Army. Delphine Johnson, Micah’s mother, has said military service changed him, turning him into a hermit.
