After Dallas police officers used a bomb-carrying robot last month to kill the sniper Micah X. Johnson, it was widely reported that the incident marked the first time an American law enforcement agency had used that technique. But it appears that the bombing was not only unprecedented, but utterly unplanned-for: According to the Dallas Police Department’s open records team, the department has no written rules, guidelines, or protocols for how or when to use bomb-carrying robots against suspects.

Hours after the Dallas Police Department sparked a manhunt for Mark Hughes, a protester who was carrying a licensed and unloaded rifle at yesterday’s march through downtown where five officers were killed, a tweet urging followers to “help us find him!” is still online. Hughes was not in fact involved with the shooting, and his attorney said that he’s received “thousands” of death threats after being misidentified.

Dallas' Police Department released a video of 27-year-old Officer Kelly Beemer getting dragged out of a bar, and another one of Beemer screaming, whipping out her gun, and firing it into the floor of her cop boyfriend's patrol car.
