It was such a powerful movement, the government had to bring in soldiers from the rural areas of the country to squash the protest. Even the local soldiers would not move against the protesters. It had a powerful impact and the world will not forget, no matter how much the Chinesse government would like them to.
Let us not forget the Kent State University Massacre, power hungry politicians are world wide. Every living person must be vigilant of their own governments misuse of power. I remember nothing happening to anyone involved in those killings either. Not one of the students was with 100 yards of the guardsmen that opened fire for thirteen seconds on unarm students.
There are no safe places from those in powerful positions. Power corrupts, absolutely!!!
