Having seen the video, it looked more like he was trying to shield his eyes from the light the police was shining directly at him _from across the street_. I don't know why this isn't reported more accurately, they shot the guy from what looks like a good 20-30 meters away.
Because they're already laying the groundwork that it was his fault, not the trigger happy cops.
Right, I said "ostensibly" above, but the cynic in me thinks, "the police got ahead of the narrative by saying he moved first". I don't really know what happened (other than a person got shot by the police when they absolutely should not have).
Yea, they wouldn't say that, because obviously it's not acceptable to shoot someone for moving their hands further up, but these days up is often down.
