TULSA, Okla. — Tulsa leaders on Thursday called for a peaceful response to a jury’s decision to acquit a white police officer who fatally shot an unarmed black man, and said more must be done to fight racial divisions in Oklahoma’s second-largest city.

The comments came after a jury Wednesday found Tulsa officer Betty Shelby not guilty of manslaughter. She said she shot out of fear Sept. 16 when she killed Terence Crutcher, who had his hands held above his head.

The initial reaction from the community in the hours after the verdict was peaceful. About 100 demonstrators gathered outside the courthouse and some briefly blocked a main street, but police kept a relatively low profile, standing about a block away.

Mayor G.T. Bynum said at a news conference Thursday that he respected the jury’s decision, but also called Tulsa’s racial divide the city’s greatest moral issue.

“This verdict does not alter the course on which we are adamantly set,” he said. “It does not change our recognition of the racial disparities that have afflicted Tulsa historically. It does not change our work to institute community policing measures that empower citizens to work side by side with police officers in making our community safer.”

At least four of the 12 jurors were crying as they left the courtroom Wednesday, and they did not look at either Crutcher’s family or Shelby. The jury comprised eight women and four men and included three African-Americans.

Crutcher’s family was quickly ushered out of the courtroom sobbing and wailing after the decision.

“Let it be known that I believe in my heart that Betty Shelby got away with murder,” Crutcher’s father, the Rev. Joey Crutcher, said outside the courtroom.

Shelby looked stone-faced when the verdict was read, but her lawyer said she was “elated” with the jury’s decision.

“She’s ready to get back to her life,” defense attorney Shannon McMurray said.

Shelby testified that she fired her weapon out of fear because she said Crutcher didn’t obey her commands to lie on the ground and appeared to reach inside his SUV for what she thought was a gun. Crutcher was unarmed.

Prosecutors told jurors that Shelby overreacted. They noted Crutcher had his hands in the air and wasn’t combative — part of which was confirmed by police video taken from a dashboard camera and helicopter that showed Crutcher walking away from Shelby, hands held above his head.

Shelby’s attorneys argued that in the two minutes before cameras began recording the encounter, Shelby repeatedly ordered Crutcher to stop walking away from her and get on the ground.

Shelby also said she feared Crutcher was under the influence of PCP, a powerful hallucinogenic known as angel dust that makes users erratic, unpredictable and combative.

An autopsy showed PCP was in Crutcher’s system, and police said they found a vial of it in his SUV.

Crutcher’s family said police attempted to “demonize” Crutcher over the drug possession to deflect attention from the fact that he wasn’t armed.
