It's time to close down the San Francisco Animal Detention Center, euphemistically known as "the Zoo." The most unfortunate and tragic tiger attack reminds us that Siberian tigers belong in ... Siberia.

Since their abduction, detained animals have no legal recourse and suffer privations of limited space and insufficient species company. From a city whose majority opposes our government's conduct at Guantanamo, I expect nothing less than dismantling and repatriation.
