He wasn’t tasered.

Say the people that lied about how many shots were fired. One OSP officer acknowledged that he drew his taser but was never asked if he deployed it. Finicum’s movements indicate that something hit him before the first gunshot. Tasers will not penetrate heavy clothing. The autopsy goes into great detail about the clothes he was wearing, several layers with an coat. When I was trained on the taser the instructor clearly stated that deployment when the subject has on heavy or several layers of clothes that the barbs will not penetrate. This is well documented and discussed. Taser even made longer barbs to try and solve the problem.
In previous grand jury testimony that was leaked out to the media, a Department of Justice agent investigating the FBI agents actions said that an Oregon trooper with a taser was getting ready to use it, but of course everyone with guns pointing at LaVoy opened up first with lethal rounds.
