From the Washington Post:
Two elderly Tibetan women lay prostrate before the Potala Palace on a recent day, venerating the 1,000-room hilltop monument that was once the seat of an independent Tibetan government and the Dalai Lama’s winter residence.
About 30 feet away, two helmeted Chinese guards observed the display of traditional Buddhist devotion. Elsewhere in the Tibetan capital, other guards barred entrance to the city’s most celebrated temples. Residents moved about their business, nervous and subdued.
One month after the explosion of violence that catapulted remote Tibet into the international spotlight, protests over Chinese policies here continue to unfold in many parts of the world, undermining China’s effort to make the 2008 Beijing Olympics a display of progress at home and amity abroad. But here in Lhasa, the most visible outcome has been relentless street patrols by men in People’s Armed Police uniforms who carry automatic rifles, check Tibetans’ identification cards at random, and guard intersections and gasoline stations.
