Federal prosecutors have decided not to bring charges in the 2019 arrest of Black motorist Ronald Greene, closing the FBI investigation into the white troopers involved in the incident. A broader civil rights investigation found a pattern of Louisiana state troopers using excessive force, including cases of violence against both Black and white suspects. The investigation revealed instances of troopers ignoring evidence of beatings, deflecting blame, and impeding efforts to address misconduct within the agency. Despite the graphic body-camera footage showing troopers using excessive force on Greene, federal prosecutors struggled to bring charges due to challenges in proving willful abuse and the death of a key trooper involved in the incident.
