Mr Nichols died three days after an encounter with police at a traffic stop
The first clip shows officers pulling Mr Nichols out of his vehicle and shouting at him to get on the ground.
“I didn’t do anything!” he says.
“Get on the [expletive] ground!” one officer shouts, as another is heard saying: “Tase him!”
An officer shouts: “Put your hands behind your back before I break your [expletive].”
“You guys are really doing a lot right now,” Mr Nichols says to the officers. “I’m just trying to go home.”
Within seconds one of the officers fires a Taser at Mr Nichols, who leaps up and manages to run away.
A separate video, from a CCTV camera mounted on a utility pole, shows officers beating Mr Nichols after capturing him in a residential area. Two officers held Mr. Nichols down while kicking and striking him with an expandable baton. They pulled him across the ground and maintained him sitting up against a squad car. More than 20 minutes passed until an ambulance is seen arriving.
Nichols’ family was presented with a private viewing of the video Monday. His mother, RowVaughn Wells, was only able to bare the first minute, family attorneys Ben Crump and Antonio Romanucci said.
