I visited the Ai WeiWei installations at Alcatraz on December 13. One of the participatory pieces called "Yours Truly" was an opportunity to send postcards to political prisoners around the world. I sent several, and brought a couple home for my remembrance. Li Tie is a Wubei writer and human rights activist who has been sentenced to 10 years in prison for subversion of state power. He wrote an essay called "Human Beings’ Heaven Is Human Dignity." Dilmurod Saidov is a Uzbek journalist sentenced to 12.5 years in prison because of his efforts on behalf of farmers' rights in the Samarkand region.
