Dallas deaths: Murder by firing squad

But the horrific toll of the rioting in Dallas, Texas, during which five policemen were shot dead by rooftop snipers, and seven others injured including two civilians, far exceeds anything that a stunned world has seen before.
Carefully planned and thought out, this onslaught was tantamount to murder by firing squad. As for motive, a suspect who was killed when a bomb exploded, according to the city’s police chief, told negotiators he was upset about the shooting of black people in Minnesota and Louisiana and wanted to kill white officers.
