This was classic lawyering - pay for your own autopsy to get the story you want. We know three thing, the guy who got shot:
1: Purchased a S&W 9mm pistol
2: That pistol was on his possession at the protest
3: A police office was shot with that pistol
The guy who got shot was then shot by the police ~50 times, so not surprising he was shot in the hand. That's not evidence of one's hands being up in the air.
