Louisville, Kentucky struck an agreement with the U.S. Justice Department on Thursday to reform its police department after an investigation prompted by the 2020 killing of Breonna Taylor found a pattern of discrimination against Black residents.

The mayor’s office said the consent decree “will set an aggressive timeline for continued police reform and provide a possible exit from the decree in five years or less.”

The plan comes more than 4 1/2 years after a Louisville police officer fatally shot Breonna Taylor, a Black woman, during a nighttime raid on her apartment.
