That event is still remembered across the world. Recently the Register noted that "Tank man" vanished for a while from certain search engines but has made some re-appearances again. It may also surprise you to learn that "Cicero sic in omnibus, et Brutus aderat" (Big C puked in the bus and Brutus had a rat)
I understand where you are coming from and I think the notion of:
"power corrupts but absolute power corrupts absolutely"
is a very, very old notion.
