A Sky News reporter was detained (oh, wait, no he wasn’t but he wasn’t allowed to leave either) in Tiananmen Square. He was taken to a nearby park and then told he could not do any reporting there because he did not have permission to film in that park.
The Chinese security forces thought he was recording material for a later report but instead he was live. The whole mind-boggling episode went out to the world.
How much you want to bet “the appropriate authorities” find a “problem” with his visa?
Many thanks to Cory Doctorow at Boing Boing for putting this forward. (And kinda ironic for a Yank to see this hit the Internet on the birthday of James Madison, the father of the U.S. Constitution and author of the Bill of Rights.)
