It is already impossible to take photos in the New York City region without being viewed and harassed as if anyone with a camera is a terrorist -- now this. While theory you only need permission if you are in groups and you are at the same place for more than half an hour but think about this: when there are no rules against photography or videography the police routinely round people up for this. What will they do when they have some kind of a vague law that they can twist in the way that works best for them?
