From the New York Times:
Federal officials have found that the Miami Police Department engaged in a pattern of excessive force that led to a high number of shootings by officers, among them episodes that resulted in the deaths of seven young black men over an eight-month period in 2011….
The number of officer-involved shootings in recent years was especially high when compared with that of other big cities like New York and Washington, Mr. Ferrer said. In 2010, he said, there was one fatal shooting for every 4,300 officers in New York, compared with one for every 220 in Miami.
In its report, the Justice Department described “egregious” delays in the investigation of officer-involved shootings by the Miami police; in one case, the officers in a shooting had not provided statements about what occurred more than three years later.
In many cases, officers were returned to duty on the streets while investigations into shootings were still in progress. Officers also showed bad marksmanship and poor judgment, the investigation found, firing their weapons at moving vehicles or when pedestrians were nearby.
