Yup, totally standard line.  The whole story talks about an injury incurred by Ryan while in the car before Finicum got out.  So the story is entirely wrong in your mind.  You ignore that the cops shot at the car before Finicum got out.  No reason.  I watched the video carefully multiple times.  I do not believe Finicum reached for a gun.  I think he was stumbling around in deep snow trying to maintain his footing.  Just because he had a gun on him does mean he went for it.  What he said is irrelevant.  Just keep asking yourself.  Why did they open fire on the car the instant it crashed?  No reason.  They were pissed, in my opinion, and in their anger decided to take him out knowing that folks like you would eat up anything excuse they gave.
