Video of Black man's death in US varies sharply from police account

Police in the US state of Louisiana have released video of a violent arrest of a Black man two years ago, in which he was dragged out of his car, shackled, and beaten, renewing calls for an end to police violence against Black people in the US.

Initial claims by Louisiana authorities that a Black man stopped after a high-speed chase had died of crash-related injuries were undercut this week by a newly released video showing police tasing, dragging, choking and beating the man. The latest controversy over a police-involved death began on May 10, 2019, when police in northern Louisiana tried to stop a car driven by Ronald Greene, a 49-year-old barber, for what they said was an unspecified traffic violation. Greene's relatives say police initially told them he died on impact when, during a chase, his car crashed into a tree.
