This video has the footage at normal and 20% speed.
From the normal speed, I really couldn't tell anything. At the 20% speed, I had known the guy was picking up the gun by the muzzle, but you can only really discern that in slow-mo.
The commentary from CNN to me was, well, CNN.
Still somewhat of a Monday morning QB job, but here goes:
Say the officer was responding knowing that the guy running had a gun, then for me, he gets a lot of the benefit of the doubt. Personally, I don't see what's so hard about dropping gun and not reaching for it when ordered so by an officer. Again, probably a Monday morning QB, but actually on what the guy who was shot and killed was thinking. Yeah, maybe he had good intentions of throwing the gun away, but if he's already viewed as a threat as armed with a gun and trying to run away from the officers, then well. . .
As for controlled pairs (still) being taught, I can confirm that it is still taught in some professional firearms courses. However, that also highlights the importance of seeking a variety of training. You don't know what you don't know.
