Jury selection began Monday in the manslaughter trial for Tulsa police officer Betty Shelby, whose fatal shooting of an unarmed black man along a quiet, two-lane Oklahoma roadway last September was caught on video and witnessed by her husband.

The shooting put the city on edge, prompting protests outside Tulsa police headquarters and a call for calm from Oklahoma Gov. Mary Fallin. Now the case again draws the spotlight, and a citywide “Prayer and Call for Justice” featuring the the Rev. Al Sharpton is scheduled for Wednesday.

Shelby, who is white, says she shot Terence Crutcher after he repeatedly ignored her commands to show his hands and kneel down. Ryan Kiesel, head of the ACLU of Oklahoma, says Crutcher was murdered “in cold blood.”

Shelby says she was driving to another police call when she came upon Crutcher, standing alongside the road, then saw an SUV straddling the center line with its engine running and doors open. Moments later, backup arrived and dashcams and a police helicopter’s camera began to roll. In the helicopter was the pilot and a police spotter — Shelby’s husband, David.

The graphic videos show Crutcher, 40, walking toward his SUV with his hands up and his back to multiple officers. Crutcher appears to place his hands on his vehicle when he falls to the ground, shocked with a stun gun fired by one officer and shot by Shelby. In the video, no one immediately attempts to provide aid to the fallen man.
