Late last week five Dallas police officers were shot and killed in an ambush attack while working at a protest against the officer-involved shootings in Louisiana and Minnesota that the News Roundup reported last week. In addition to the officers who were killed, nine other officers and two civilians were injured. The Dallas Morning News has comprehensive coverage of the attack here. It has been reported that the gunman, Micah Xavier Johnson, “was upset about the recent police shootings” and said that “he wanted to kill white people.” Johnson had served in the military and carried out the ambush from an elevated position using an assault rifle; he was killed by police using a bomb robot after a standoff.
