This is indeed tragic but I'm wondering why in the heck he would walk back to his door and reach into his truck. It's a shame we don't have access to the full audio feed but I could never imagine the officers saying "with your hands up please mosey on back over to your door and grab some ID through your window".
@schuylaar why would you consider this "the litmus if there ever was one"?
Just 2 minutes worth of digging reveals that at one point during his lifelong criminal career we have this incident, which was before the 4 your prison stint he recently served for trafficking:
"Records obtained by The Associated Press on Tuesday show that when Crutcher was ordered to exit the vehicle for a pat-down search, he began making a movement to his right ankle before an officer managed to get control of Crutcher. A .25-caliber pistol was found in his right sock, the arresting officer wrote in an affidavit."
