I guess this really shouldn’t be surprising to anyone:

China locked down Tiananmen Square on the eve of the 20th anniversary of the crackdown on pro-democracy protests there.

Several hundred police, paramilitaries and other security personnel
swarmed over the square in the heart of Beijing, where the army crushed
seven weeks of protests on the night of June 3-4, 1989.

Police
examined visitors at security checkpoints dotted around the square,
scrutinised bus passengers disembarking on nearby streets and checked
the bags and papers of people approaching the square from surrounding
neighbourhoods.

Leading dissident Qi Zhiyong, who lost his
left leg in 1989 and is under nearly permanent police surveillance, was
forcefully taken out of Beijing early on Wednesday, he told AFP.

“Every
day I must send my daughter to school in a police car. Today after
seeing off my child, the police refused to allow me to get out of the
car,” Qi said in a text message.

“Instead two additional
police got in the car, forced me to sit in the middle, and they are now
taking me out of Beijing. They are going to take my phone away.”

Subsequent
calls to Qi’s phone went unanswered. Qi, 53, had earlier refused to
leave the capital after police had requested him to do so.

Hundreds,
possibly thousands, of people were killed in the Tiananmen crackdown,
and the events of June 3-4, 1989 remain a taboo subject in China.  [Herald-Sun]
