The Justice Department opened a civil rights investigation Thursday of the Louisiana State Police, launching the review after a series of videos showed officers brutally beating Black motorists. One particularly violent video showed state troopers punching, stunning, and dragging an unarmed man, Ronald Greene, as he apologized for failing to stop during a high-speed chase in 2019. He died shortly after, but state police initially told his family that he was killed when his car hit a tree. "We find significant justification to investigate whether Louisiana State Police engages in excessive force and in racially discriminatory policing," said Kristen Clarke, the assistant attorney general in charge of the civil rights division. State Police Superintendent Lamar Davis has said he would welcome the Justice Department investigation. Two-thirds of his agency's uses of force have been directed at Black people, he [said]. Greene's arrest was one of least a dozen over the past 10 years in which state police troopers or their superiors ignored or concealed evidence of beatings. Under Attorney General Merrick Garland, the Justice Department has opened similar investigations of police departments in Minneapolis after the death of George Floyd and in Louisville, Kentucky, following the death of Breonna Taylor.
