Charlotte, n.c. — In the shaky video she shot on her cellphone, Rakeyia Scott can be heard trying to save her husband’s life.

“Don’t shoot him!” she shouts to the Charlotte police officers who surrounded her husband this week in the parking lot of a condominium complex. “He has no weapon.”

As police officers scream at 43-year-old Keith Lamont Scott — “Drop the gun! Drop the gun!” — his wife tells them: “He doesn’t have a gun.”

Soon four shots can be heard, followed by Rakeyia Scott’s screams.

“Did you shoot him? Did you shoot him? Did you shoot him?” she screams as she walks closer to the scene, still shooting from her phone. “He better not be dead, he better not be … dead.”

Soon, she was using the phone to call 911, her husband’s body splayed on the ground.

Attorneys for the Scott family on Friday released the first publicly available video of Tuesday’s shooting as Charlotte continued to reel from days of protests that have focused, in part, on city officials’ refusal to release police footage of the incident.

“Release the tapes!” has become a familiar refrain on Charlotte’s streets. Republican presidential nominee Donald Trump has called for an end to “the rioting” in Charlotte, while Democratic nominee Hillary Clinton zeroed in on the video, calling for release of the footage “without delay.”

The debate in Charlotte has once again highlighted the uneven level of transparency that exists in cases of police shootings across the U.S.

Days earlier, police in Tulsa, Okla., had quickly allowed the public to see disturbing video of another line-of-duty shooting, this one involving a white police officer and a black motorist who died with his hands in the air.

Many cities do not have fixed policies about when to release crucial footage of a police shooting, and such killings frequently turn into chaotic political struggles. In many cases, family members, activists and social media users turn up the pressure on local officials, as happened on Friday in Charlotte, by releasing their own footage.

The public now may have media tools as good as or better than those of the police. Encounters with police are sometimes now live-streamed as they happen, a tactic clearly intended to influence the outcome in real time.

After a shooting, members of the public can release their own footage when they believe that police have not described an incident truthfully.

Such pressure is unusual for police investigators, who in other kinds of cases are typically allowed to hold off on releasing video recordings of an incident. The reasons are many. A video of a crime, for example, can often be used to test whether a suspect is lying or a witness is remembering an incident accurately.

Indeed, release of a video may cause confusion about whether a witness is describing what they saw during a crime or what they saw on the video.

Charlotte Police Chief Kerr Putney has said release of the official video would be counterproductive and could potentially compromise the integrity of the investigation — though in a small concession, he did permit Keith Scott’s family to view it.

“It’s not that I want to hide anything,” Putney said at a news conference on Friday morning. “I want to be more thoughtful and deliberate. If I were to put it out indiscriminately and it doesn’t give you good context, it can inflame the situation, exacerbate backlash, increase distrust.”
