Chinese government attacked student protesters for democracy June 4, 1989 at Tiananmen Square in Beijing with assault rifles and tanks. The protesters were unarmed. The Communist government’s official death toll was 241 = 23 police/soldiers and 218 civilians. But observers say it was at least double that. Is it a defense that most of the deaths took place outside Tiananmen Square in western Beijing?
And the crackdown after was massive and cruel. All ranking Communist Party officials who opposed martial law were removed from office, except one or two who “corrected” their opinions.
We remember the hope of the students gathered and the cost of their sacrifice. In China they are intent on forgetting both. See USA Today
