It used to be that such abductions by the government didn't happen here in the U.S.--but now we have the Patriot Act, and it does.

Suddenly you're in the Spanish Inquisition, 21st century version.
So we can no longer be smug that these things don't happen to us. Though they are still less likely to happen to those of us who have white skin--unless they think you're an "eco-terrorist" or a white supremacist militia member.
I hope the pressure lets up when everyone leaves Beijing and the government there is less concerned with foreigners seeing their dirty laundry.
