Olympic Torch Politics: San Francisco Today, Buenos Aires on Deck

San Francisco police, sheriff's deputies, agents from the Department of State and the FBI are all gearing up for today's Olympic Torch Relay on San Francisco's Embarcadero. Meantime, the International Olympic Committee may curtail visits to other cities and it's backed away from a statement urging China to settle its conflicts with Tibet. When the torch was carried through crowds of protesters in London and Paris, guards included a Chinese paramilitary force.
