That is a good question. I would think the prosecuting attorney would have demanded it be shown.
The one shocker is that the cop who did the shooting on the video was NOT the cop issuing the commands to the victim. That cop was a more senior officer. In my opinion, he should have been brought up on charges as well. His spoken commands were nonsense. It was as if he wanted the victim to be shot for noncompliance with his orders. According to the news article, he “retired” shortly thereafter and moved to The Philippines.
That's exactly what I thought as I listened to the audio myself. Personally I could never have physically complied with some of the orders he was shouting out, especially the part about having one's legs crossed behind them while kneeling.
Someone like me would've been shot just for that! (I'm partially disabled, btw.)
