I'll give you a brief summary. An official Olympic Torchbearer was holding the torch marching down the streets of San Francisco. About 30 Chinese paramilitary "special police" (Communist police) are guarding the torch during the march through San Francisco, California. The torchbearer decided to carry a Tibetan flag during her run down a public street, in THE UNITED STATES OF AMERICA, choosing to exercise her 1st Amendment right in a public place. The Chinese paramilitary police ripped the flag from her hands and then San Francisco Police pushed her out of the march.
