But _did_ Li know?
>Li surely knew he was tempting fate with even an oblique reference to the fact that China's government used tanks and troops to suppress and kill protestors on that day.
But did he? The irony is the Chinese government has been so throughly successful in wiping this event from common knowledge that many people have no clue it ever occurred. Li must be well versed in navigating government censorship laws to have become so successful, so it seems unbelievable he'd make such a mistake. It seems more likely he simply didn't know, but now he surely does. Streisand effect ftw.
