(First time posting, some thoughts IMO and hope to contribute to peoples questions)
I do like you thoughts on this, my only addition might be that objectively it might show that he is not one to shy from physical force when a confrontation arises, which does run contrary to the gentle giant narrative. IMO when confronted with a being up to no good as a child I would usually try to talk my way out of it before resorting to physical force.
Well I know in Canada its center of mass, but given the amount of shots fired in the frame of time we have (based on the video when the gunshots in the background) I would suspect muzzle jump would be a factor, basically the recoil from firing your shots, more shots fired would reduce your accuracy significantly (based on my own experience with firearms)
Darren Wilsons sidearm was suggested as being a Sig Saur P229 .40 Caliber. According to a post from the S&W forum.

Listening to the video it sounds more like it then a Glock .45, which is very common in law enforcement these days.
To show some idea of muzzle jump I got a link of someone firing a Sig .40 at a shooting range, note the recoil, granted the person firing the firearm is likely a novice based on how sloppy her grip is, but still unless OW is a hulk of a man, and considering he was supposedly injured, the recoil would likely have not been negated

By Comparison a Glock .45 which is common in law enforcement

Too close together to be casings IMO, also given the # of shots it would seem odd there are not more casings in that spot if it were.
Sorry for the long post, was a lot of things I wanted to touch on.
