China had deported six members of the group Students for a Free Tibet after they hung a banner on the Great Wall that read “One World, One Dream, Free Tibet 2008.” The group included three Americans: Leslie Kaup of St. Paul, Minnesota; Nupur Modi of Oakland, California; and Duane Martinez of Sausalito, California. Earlier this week, Amnesty International criticized China for failing to improve its human rights record ahead of next year’s Olympics in Beijing.
