Too Little Too Late

This sort of response (at Cal-Berkeley) might have been effective early on in the protests; now it's just going to enable the protestors. Note particularly that despite some pretty vigorous thrusting of the clubs by the cops, none of the protestors seems seriously injured. They back up a bit, but none of them make a significant effort to get away. I'm forced to conclude that the beating was not as brutal as it might appear at first glance.
