The shooting was on the 22nd. in Alanta. I won't debate the legalities, but I like how the second shooter spun back to the crowd ready for anything, but the pistol was pointed at his feet and ready for whatever else was going to pop up.
My understanding of the event is another person had already shot the suspect, out of camera view. His SA was spot on in my opinion knowing there were many people behind him, but not knowing if there was a threat there too.
This post is strictly about the tactics on camera.
