Detroit police arrested four men for allegedly threatening on Facebook to kill police officers, police Chief James Craig said Sunday.
One of the men reportedly posted: “All lives can’t matter until black lives matter. Kill all white cops.”
The arrests of the four African-American Detroiters follow Thursday’s slayings of five Dallas officers by a black sniper during a protest march. The man blamed for the killings and injuries to seven others reportedly told police he wanted to kill as many white cops as possible.
Law enforcement agencies across the United States are on guard for threats after officers have been shot in at least three cities since Thursday’s attack.
Long-simmering tensions were inflamed last week when video captured officer-involved killings of African-American men in New Orleans and Minnesota. As a crowd gathered in downtown Dallas to protest, police say military veteran Micah Xavier Johnson, 25, of Mesquite, Texas opened fire.
