Good one. If only you had bothered to click the link in my comment, you would see a well sourced article that does in-fact thoroughly debunk this propoganda that you've internalized so much.

Some highlights:

• Full tank man video (he leaves the square unharmed)
• An eye witness account from a Latin American diplomat
• CBS News agrees

There's more, but if you're not willing to even consider that you've been lied to about this event, then there's really no point in me putting in any more effort.
