The Olympic torch relay in London was unceremoniously greeted with demonstrations and protestors who tried to snuff it out with a fire extinguisher, grab it away from a runner, and threw themselves in front of its path. At one point, the torch had to be put on a bus to get away from a surrounding crowd of demonstrators. French police officers are mobilizing for the next leg of the journey, and San Francisco has canceled any police days off on Wednesday for the torch run there.
