Smile, you're on...
London's candid camera. These cameras MAY help ID some suspects. Although I disagree with the cable TV and press queried "experts" (like I know) claiming that the attack took large #s of people and many months to prepare, I do not agree that one or even two folks are in on it. My guess is a single digit # >2. Very telling that low tech explosives were used. In the real world, the facts of the situation are often stranger than we imagine based upon our preconceptions. Who called the OK City or WTC scenarios before they happened?
