Britons, take note: Darren Cullen has a timely reminder about the London Police's new powers. The new biting powers will be useful alongside the ASBO, detention without charge, the right to seize domain names, illegal harvesting of innocent peoples' DNA, the right to arrest you for reading things that might help terrorists, the right to kettle legal demonstrations, the right to shoot people in the street, the right to beat people standing near demonstrations to death, the right to arrest you for taking pictures that might help terrorists, and all the other legal doctrines that are so consistent with all the invisible words in our "unwritten constitution."
