回复：还是因果问题。没有军队开枪，群众也不会扔石头，不会骂“法西斯”；没有装甲车朝人群碾去，何来群众投掷燃烧瓶？

"没有军队开枪，群众也不会扔石头". You are wrong. I watched CNN before 6/4/89. Even CNN showed that somebody threw a big brick at a soldier. hit his head. The soldier fell down immediately. He lost conscious. Another soldier picked him up and waked away. They did not even try to fight back.
I am a pliceman in US. If somebody treats like that,( I mean that he try to attack me,and when I feel my life or my parter life in immediate danger), I shoot him.
