This is the enhanced video
When someone exits a vehicle with their arms in the air - that is a universal gesture of surrender. The Officer in the lower right places both hands on his gun, takes aim then you see a recoil - immediately after, you see Finicum lowering his arms to the position on his body where the officer had aimed.
The official statement from the FBI was that he was reaching for a loaded 9mm in his left pocket. All of the pictures of Finicum shows him wearing a .45 on his right side.
(ever since the Waco investigations, I have questioned the motives of my government, we are still allowed to do that).
now, to clarify, I am not assigning blame on the LEO's in this incident. Finicum has made several statements that he would rather be killed than taken to jail. But ... this really looks to me as if he was attempting to surrender. I am also finding out that none of the video released by the FBI has any audio. There are also no dashcam or bodycam footage to speak of. I question these things, not because I am paranoid, but because I know corruption in government is rampant.
Also, there was an 18 year old girl inside the vehicle with Finicum that made a statement that he bolted from the first stop because he was shot at when he stuck his head out the window. Now ... no way for anyone to determine if this happened or not, due to no audio being released. i am just reading this stuff around the interwebz and I do realize a lot of it is speculatory BS.
