By the way, at your Youtube link there, the guy is misreading what the article he quotes says about the taser. That article doesn't say the taser was used. It says the officer with the taser stepped through the snow toward Finicum, and that he was attempting to subdue Finicum with less than lethal force. However, at that moment, Finicum reached for his weapon and he was shot by other officers. He was never tased. The taser was not deployed at all, and that article doesn't say that it was.
He was messing with the wires. You can see it on the video. :)
The gun in his pocket was not the same type of gun he carried in his holster. You know that.
