Whatever your views on what David Blaine is doing or trying to prove there's no denying that the stunt itself is a spectacle and is pulling in the crowds. I thought I'd stop by as I was in London for the day and was amazed at how many people were here just gazing up at this guy in his box. They wave and he waves back. Meanwhile, somewhere else in the world, another person dies of starvation. I expect that nobody was there to wave them off.
