Between 2015 and 2019, 13,392 misconduct complaints were filed against 1,800 Baltimore police officers, according to an American Civil Liberties Union review of data provided by the city. In a single month in 2017, a total of about 800 officers were patrolling the streets, the ACLU noted. The department says it has a total staff of more than 3,100 civilian and sworn officers. About 6% of officers accounted for a third of complaints.
The city, under a 2017 court settlement, has pledged to reform department conduct that the Justice Department found to be unconstitutional and illegal. The ACLU noted that the complaints were “sustained” at low rates, “even when officers admit to the misconduct.”
Baltimore County operates a separate police department. Its force of about 1,900 officers received 120 complaints in 2019, according to the county's dashboard.
