Stop the Robberies, Enjoy Safe Streets

Stop The Robberies, Enjoy Safe Streets was a Detroit [Police Department] unit that operated from 1971 until 1974.
STRESS was created to reduce crime in Detroit by surveilling and catching criminals in the act. It used decoy units, targeting African-American men. It led to the deaths of twenty-four men, twenty-two of them African-American, over the course of three and a half years.
A 1973 poll found that 65 percent of black Detroiters disapproved and 78 percent of white Detroiters approved of STRESS.
