In both New York and in Portland, to my knowledge, the police chose the middle of the night to break up the Occupy movement encampments. Now, there may be argument abouts the propriety etc. of these encampments (personally I support them), but what was the reason for the nighttime raids? The only reason I can think of was to make it more difficult for onlookers to videotape or capture photographs of the process. Lord Bloomberg practically said so when he claimed journalists were excluded "for their own protection." TSA de facto does the same thing, no matter what they say on their website. Again this is part of the strategy behind the security state, which is to operate in the dark, literally so in the case of the Occupy raids. In TSA's case, of course they can't actually turn out the lights in the checkpoints (now that's a creepy thought!) but instead we see multiple examples of retaliation, such as deliberate withholding of complaint forms, blocking videos from being made, intimidation of persons making videos etc. The point that the security state is endangered media attention cannot have made more graphically than in the images of the brutality inflicted on 11 UC Davis students who were committing the terrorist act sitting on a sidewalk with their heads bowed and their arms linked. On the other side of the coin, the extent to which the security state feels it is immune to challenge is shown by the open carrying out of the chemical attack by the officer in question before numerous witnesses.
