That's not what you said in post 14:
"LaVoy went to the Taser prongs sticking out of his left back - not his shoulder holster."
You keep flogging this Taser hypothesis with no evidence on your side. In fact, the video argues against you.
I initially agreed with your analysis, but no longer agree after having watched the video a few more times.Based on the video, the officer to the left was not a shooter, but was using a taser. I say this for four reasons:
(1) He has the weapon in his left hand in a single handed grip, and I see no evidence of recoil in that left hand;
(2) He reaches with his right hand for his right hip while using the weapon in his left hand. This movement only makes sense if he is reaching for a pistol for the event that his less lethal weapon is ineffective;
(3) He would not have a safe shot. Police are not known as the best shots, and his line of fire would have exposed the entire roadblock to his fire; and
(4) It appears as if you can see this officer stripping (like in fly-fishing) wire from the taser as he walks around Lavoy.
I don't think anyone at the roadblock shot Finnicum. Going back to point (3) above, none of the police at the roadblock would have had a safe line of fire because of the position of the officer in the upper left.
The only shooter was likely the officer in the lower center as he was the only officer with a safe line of fire.
With this said, it seems that the officer in the center shot much earlier than the officer with the taser, and it seems likely that Lavoy was reacting to the impact of bullets when he went for his side.
Overall, this isn't open and shut and the video doesn't resolve doubt as to whether Lavoy was murdered or justifiably killed by the officers at the roadblock...
But it was that close.
I had to go with the transparent metric ruler. :)
