You haven't.
You've said you have questions but haven't told us what they are.
I'm assuming he meant this.
the arm movement thing is bothering me because I can't be certain if it's reaction or the dude going for something. I get the debate going on about it but I'm not quite convinced. That's why I want to see if more info comes out. I know if I was pointing my weapon at someone and they made a quick movement, I can't say I wouldn't do the same damn thing. It doesn't take long to react when you are already in position to use your weapon.
The breakdown that Bronzewolf made satisfied my questions about that. Seems like there's a big enough margin of error in those numbers that it's a for sure thing.
I have analyzed the video.
The Facts
From the maximum zoom and vantage point of the video, I would guess the microphone is positioned at no closer than 140 meters (Give by google maps estimations). According to research, average police officers take about 250 ms trigger reaction time. Sound travels at 340.29 m/s.
What should be the time difference between the perp's movement and the gunshot sound at the mike if he was shot after he moved?
At 140 m, the gunshot would be heard 410 ms after the officer completely pulled the trigger. If we add a faster than average reaction from the office at 200 ms, then the gunshot should be heard 610 ms after we see the perp's movement. Anything less than this difference would clearly indicate an unjustified gunshot.
Video Timestamps
Using Windows Movie Maker I was able to both slow down the video playback up to the milisecond.
01:51+500ms Perp starts to raise his arms
01:55+330ms Perp starts to lower his arms
01:55+600ms First gunshot is captured by the mic
Time difference: 270 ms
The conclusion
Of course an amateur video like this would be difficult to show with certainty the real timeline of events. A person reaction to a wound is very fast and it could be confused with a hostile movement from afar.
While my analysis is amateurish, everybody can do it with more advance tools that could a) clean the sound in order to pinpoint the 1st gunshot timestamp better and b) Do a better analysis of the distance between mic and the gun, the time difference is just way too small for the gunshot to have happened before the perp's moved his hands. EVEN with a camera right next to the gun, the officer would have to be 50% more accurate than average police officers in order to react in such a fast way to the shot.
