Most traffic stops do not involve armed militants that resist arrest, engage in a high speed chase, try to dodge a road block and then jump out like an idiot after nearly running over an officer.  The agents had no idea what Finicum's intent was when he jumped out, or that of his passengers with their stash of  weapons.

The initial shots were fired high, I believe as warning shots.  Fincum was not ambushed and did not follow orders to surrender and kept reaching for his pockets.

About a week later in Seaside, two officers attempted to arrest a suspect who managed to fatally  shoot one of the officers while his hand was in his coat pocket.  

Case closed,
