Over at Volokh Conspiracy there's an interactive poll that lets readers watch a video of the police tasing a D.C. Occupy protestor & then indicate whether the police were acting appropriately. The comments are great demonstration of how people with different ideological predispositions will actually see different things in a situation like this, a recurring phenomenon in the reactions to use of force by police against Occupy protestors. I'm pretty sure the author of the post -- Orin Kerr, who'd be a refutation of the phenomenon of ideologically motivated reasoning if he weren't a mere "N of 1"-- designed the post to make readers see that with their own eyes regardless of what they "saw with their own eyes" in the video. Nice.
