Giving you contradictory orders is standard operating procedure whenever cops need an excuse to abuse or kill you:
Cop1: “Get on the ground!”
Cop2: “Don’t move!”
Cop1: “I SAID GET ON THE GROUND!”
Cop2: “I SAID DON’T F*CKING MOVE!”
But hey, you were being “uncooperative” and that’s what the record will show, even though it’s literally impossible to follow both orders at the same time.
