The story seems to read that he only was starting to cooperate once he heard the cop say he was going to taser him.
I think the officer accidentally drew the wrong weapon. It’s not an excuse for him, or that he shouldn’t face the consequences, I think he drew the wrong weapon.
And I think this will also force the PD to implement different training and placement of weapons if they are going to have both tasers and pistols.
I like to think he drew the wrong weapon too. Unfortunately, I guess we will never no. Nonetheless he should be given the same benefit of the doubt that you and I would be given in that situation, if you shot someone you had face down and prone being partially restrained by a couple of your buddies: Zero.
