The agency that investigates allegations of police brutality received 1,367 such complaints during the first seven months of 1990, slightly less than the 1,420 complaints it received for the same period in 1989. And though it received fewer complaints, the Office of Professional Standards (OPS) has sustained, or upheld 74 complaints this year, about the same (75) as in 1989. The Chicago Reporter analyzed police data one year after widespread charges of police brutality swept the city. The Reporter reviewed data on OPS complaints for the years 1986 through 1989 and for January 1 through July 31, 1990, the most recent data available. Among the four complete years studied, 1987 had the most complaints.
