The first week of Tulsa police officer Betty Shelby's manslaughter trial produced a whirlwind of revelations about the chance encounter that left Terence Crutcher dead and the contentious aftermath of the high-profile police shooting.
A white Oklahoma police officer charged with manslaughter in the fatal shooting of an unarmed black man has testified that a training video ran through her mind as she pulled the trigger.
Shelby's attorneys brought up some of Terence Crutcher's criminal history in court Monday.
On the sixth day of trial, Shelby testified that videos she saw in training indicated that if suspects are allowed to reach into their cars, "they can pull out guns and kill you", the Tulsa World reported.
Crutcher ignored her order - and also ignored orders from her and another officer, Tyler Turnbough, who arrived on the scene, Shelby said.
Another police supervisor testified that he told Shelby not to talk about the incident because he knew it would be racially explosive. He said Crutcher was "noncompliant" and "defiant", resulting in a stun gun being used twice.
Shelby told the jury that she was taught during law enforcement training that if a suspect reaches into an area like a vehicle, an officer does not let them pull their arm back because they might be holding a gun, the Tulsa World reported from the court room.

Shelby's attorneys called her to the stand around 11:30 Monday morning, asking her about her training and career. They blame her for turning a routine traffic matter into a deadly confrontation by acting unreasonably and escalating the situation.
On Monday, Shelby took the stand in her own defense. She asked Crutcher about the SUV, including whether it was his, but got no response. The 12-member jury consists of three African-American jurors after an African-American alternate juror replaced an Asian juror who fell ill on Monday.
"It's a small gesture, but it means a lot", she said.
Several members of the gallery wore purple and green ribbons Monday in support of the Crutcher family.
During cross examination, Assistant Tulsa County District Attorney Kevin Gray asked Shelby why she didn't use her Taser.
He said she later apologized to the class.
Jurors will hear from additional witnesses on Tuesday.
