Castle Onslought with a Cardboard Tank

In case anybody was wondering about the NATO summit, it went very smoothly. There was a plot to disrupt electricity to the summit area, but those responsible were caught about a week before the event took place, so nothing tremendously exciting happened. Demonstrators made a large cardboard tank and tied a knot in the barrel, then two of them carried it up to the police line guarding the summit, and dropped it there. Then they walked away. So, nothing tremendously bad. Two years ago there was an IMF summit here, and that resulted in Molotov Cocktails being thrown and a number of destroyed buildings and such. This year the police were much more well-prepared.
