CHARLOTTE, N.C. (Reuters) – Officials in Charlotte, North Carolina on Sunday geared up for further protests over the police killing of a black man, a day after police released videos of the confrontation that did not show whether the victim had a gun when he was shot.

After nearly a week of protests, city officials were preparing for extra security at a National Football League game between the Carolina Panthers and the Minnesota Vikings on Sunday afternoon, bracing for more demonstrations over the killing of Keith Scott, 43, who police said was armed when officers shot him on Tuesday.

Small groups of police in riot gear stood around Bank of America Stadium as fans arrived about two hours before kick-off in a jovial mood. Officers shook hands with some of them and posed for pictures as a group of about 30 protesters gathered with signs.

“Black lives matter,” the demonstrators chanted. “We don’t need no riot gear. Why are you in riot gear?”

Scott’s death has made Charlotte, the state’s largest city and one of the U.S. Southeast’s most vibrant urban centers, the latest flashpoint in two years of tense protests over U.S. police killings of black men, most of them unarmed.

Charlotte-Mecklenburg Police Chief Kerr Putney said his department expects to “expend significant public safety resources” at the arena, which can hold more than 70,000 people.

Charlotte declared the game an “extraordinary event” under its municipal code, giving police the power to stop people from carrying blades, projectiles and other objects into a certain area.

The previous night, hundreds of people marched through the city center on a fifth night of demonstrations that stretched into Sunday morning, including white and black families protesting police violence.

A Panthers fan sympathized with the protesters but did not think they would succeed in changing policing.

“I get the message the protesters are trying to send,” Joe Mader, 24, said. “I think it’s smart that they’re out here. I’m happy to have them here.”

On Saturday, police released videos showing Scott’s shooting in the parking lot of a Charlotte apartment complex.

Putney acknowledged that the videos themselves were “insufficient” to prove Scott held a gun but said other evidence completed the picture.

Police said officers trying to serve an arrest warrant for a different person caught sight of Scott with marijuana and a gun, sitting in a car in a parking lot.

Both Scott’s family and protesters have disputed the police statements that Scott was carrying a gun.

Police released photos of a marijuana cigarette, an ankle holster they said Scott was wearing, and a handgun, which they said was loaded and had Scott’s fingerprints and DNA.

But Scott’s family, which released its own video of the encounter on Friday, said the police footage showed the father of seven was not acting aggressively and that the police shooting made no sense, with no attempt to de-escalate the situation. The family video, shot by Scott’s wife, was also inconclusive on the question of a gun.

In one of the police videos, a dashboard-mounted camera from a squad car showed Scott exiting his vehicle and then backing away from it. Police shout to him to drop a gun, but it is not clear that Scott is holding anything. Four shots then ring out and Scott drops to the ground.

A second video, taken with an officer’s body camera, fails to capture the shooting. It briefly shows Scott standing outside his vehicle before he is shot, but it is not clear whether he has something in his hand. The officer then moves and Scott is out of view until he is seen lying on the ground.

At least five people who appear to be police officers are seen in the bodycam video. Both videos show Scott moving at a measured pace with his hands at his sides.

Another lawyer for the Scott family, Charles Monnett, said, the family did not know enough of the facts to know whether the officer who killed Scott should face charges.

The two-minute video recorded by Scott’s wife on a cell phone showed the scene of the shooting, but not the shooting itself. In the video, Mrs. Scott can be heard telling officers that her husband has TBI, a traumatic brain injury.

“Don’t shoot him! He has no weapon” she cries as police yell at Scott, “Drop the gun!” Then shots sound.
