I agree 100%, don't put yourself in the position to tempt LEO to shoot you, period.
That being said, a media co-worker brought up an interesting point. The snow looks pretty deep and that he was having a hard time balancing himself, based on this video, how do you know he was not trying to catch his balance?
Things happened pretty quick it looks like, I hope they release the other video they claim shows him reaching for the gun.
99% of the time I support LEO, they have a job that is harder than just about any e-expert out there. Unless you are in LEO, you don't have a job where your customers might shoot at you, try to run you over, spit at you, ect...
