A National Guard soldier watches in Charlotte, N.C., Friday, as demonstrators marched in the streets of the city to protest Tuesday's fatal police shooting of Keith Lamont Scott.

CHARLOTTE, N.C. — Demonstrators carried signs, chanted and marched in a peaceful protest hours after the family of a black man shot by police released video showing the events leading up to his death.

Friday’s march through Charlotte’s business district was the fourth night of demonstrations over the shooting of Keith Lamont Scott earlier in the week.

After darkness fell, dozens of people took to the streets to urge police to release dashboard and body camera video that could show more clearly what happened. Police have said Scott was armed, but witnesses say he held only a book.

The group, which appeared smaller than previous nights, carried a banner that said “Just Release the Tapes.”

Earlier in the day, footage recorded by Keith Lamont Scott’s wife and released by his family shows his wife repeatedly telling officers he is not armed and pleading with them not to shoot her husband as they shout at him to drop a gun.

The 2½-minute video released by the family does not show the shooting, though gunshots can be heard. In the video Scott’s wife, Rakeyia, tells officers that he has a traumatic brain injury. At one point, she tells her husband to get out of the car so police don’t break the windows. She also tells him, “don’t do it,” but it’s not clear exactly what she means.

As the encounter escalates, she repeatedly urges police, “You better not shoot him.”

After the gunshots, Scott can be seen lying face-down on the ground while his wife says, “He better live.” She continues recording and asks if an ambulance has been called. The officers stand over Scott. It’s unclear if they are checking him for weapons or attempting to give first aid.

Earlier in the week, the Charlotte protests turned violent, with demonstrators setting fires and smashing windows.
