Charlotte shooting: Kin releases shocking video

African- American man whose death has triggered days of unrest in Charlotte, North Carolina, released a dramatic video of the police shooting on Friday, raising pressure on the authorities to make their own footage public.

The police have refused to release body-cam and dash-cam video of the shooting Tuesday, which they say shows Keith Lamont Scott posed officers a threat.

His death is the latest in a string of police-involved killings of black men that have fuelled outrage across America.

Charlotte has been rocked by three nights of violence-marred protests, prompting the governor to declare a state of emergency in the southern US city.

Hundreds of protesters were out again on Friday calling for the release of the videos amid a greater presence of National Guard troops, but the atmosphere was calmer than during previous days.

Demonstrators were also marching in the southern city of Atlanta in a protest calling for police reform organised by the NAACP, the black community’s main civil rights organisation.

Charlotte’s case has also touched the US presidential race, with Democrat Hillary Clinton’s campaign announcing her plan to visit the city on Sunday before postponing it to a week later after Charlotte mayor Jennifer Roberts asked both major candidates to delay visits, citing “very stretched resources for security.”

President Barack Obama called for understanding as he celebrated the opening of the Smithsonian’s African American museum in Washington this weekend.
