Yup. Same old same old. Two-handed baton thrusts to a guy's head while he's on the ground.
I disagree with you that he used extreme force. I do not care for LE being in my business, but in that situation, where he is way out numbered, and he needs to gain the upper hand quick, I have no problem with what he did. The guy should not have hit him. If the guy had not struck him, and was just mouthing off and the cop did this, I would have a major problem with it.
Side note, what Octoberfest is that?
