When Lavoy is out of the PU, why are they shooting through the cab roof?
The shot that went into the roof was while the truck was approaching the barricade, before he swerved into the snow bank on the left.
At 5:22 you hear the first shot hitting the cab and Finicum says "hang on" and then the girl says "they're shooting", followed by the sound of the second shot hitting the cab.
These officers who are all on the pavement and behind the vehicles realize that at his rate of speed he will not be able to stop.
The first two officers abandon their position and move into the snow bank on the right side of the road
By 5:25 the third officer is moving into the snow on the left side just as Finicum is swerving to the left. If the snow had not stopped the truck, the third officer would have been run over.
People really need to watch and listen to the whole sinc'd video. It appears from that video that the three shot fired at Finicum were fired when he ignored multiple verbal commands and dropped his hands to his jacket. We will never know if he heard those commands because he was too busy screaming "go ahead and shoot me!"
Had he complied at the first stop instead of yelling at agents to go ahead and kill him, he would be in jail with the rest of his compatriots.
