The Louisiana State Police unit that killed Ronald Greene, a 49-year-old Black man, by tasering, punching and dragging him during an arrest in 2019 is under an internal investigation looking into whether officers are systematically targeting Black motorists for abuse. That’s according to the Associated Press, which reports investigators are probing the violent arrests of three other Black men by the same police unit: one who was punched, stunned and hoisted to his feet by his hair braids; another who was beaten after he was handcuffed; and yet another who was slammed 18 times with a flashlight. The investigation is focused on white officers with State Police Troop F — a notorious unit in northeastern Louisiana whose officers have mislabeled body-camera videos, turned off their cameras during arrests, and otherwise worked to hide evidence from investigators. Some of the troopers already face felony charges.
