NEW ORLEANS — Louisiana State Police troopers involved in the violent arrest of a Black motorist who died in police custody in 2019 should be fired and arrested, leaders of the National Urban League and other civil rights groups said Thursday.

Marc Morial, the national president of the Urban League and a former mayor of New Orleans, discussed the arrest and death of Ronald Greene at a morning news conference with other state and local civil rights groups, including the American Civil Liberties Union and the NAACP.

Meanwhile, Greene’s family planned to speak at a rally later Thursday at the State Capitol in Baton Rouge.

Video obtained by The Associated Press and later released by state police shows troopers stunning, beating and choking Greene, 49, following an automobile chase and crash in northeast Louisiana in May 2019.

Greene’s family was initially told that he died in the car crash. State police later issued a brief statement acknowledging there was a struggle with officers and that Greene died on the way to the hospital. Since then, Greene’s death has come under investigation by state and federal authorities. It also is the subject of a lawsuit.

The video shows troopers converging on Greene’s car outside Monroe, Louisiana, after a high-speed chase that followed an unspecified traffic violation. Troopers can be seen repeatedly jolting the 49-year-old unarmed man with stun devices, putting him in a chokehold, punching him in the head and dragging him by his ankle shackles.

He also was placed facedown on the ground for more than nine minutes while restrained — a tactic use-of-force experts criticized as dangerous and likely to have restricted his breathing.

An autopsy cited the restraint and an “inflicted head injury” as factors in Greene’s death, along with cocaine-induced delirium and other injuries that might have been the result of the car crash.

The ACLU of Louisiana said the afternoon rally will include representatives of the NAACP of Louisiana and Greene’s family. After remarks on the Capitol steps, the group plans a march to the Governor’s Mansion.
