Unfortunately I also saw the videos and pictures of tanks grinding bodies into pulp and washing them down drains shortly after this… That one certainly made me think.

No you didn't, because no such video exists. No such video exists because that story -- of pulping bodies and "washing them down drains" -- is ridiculous, impractical nonsense made up by someone who wasn't even there (I forget if it was student leader Chai Ling or one of the reporters sitting in their Beijing Hotel room who is responsible for that specific gem, but both lied about witnessing things they weren't there for).

Why do you need to lie about what you have seen in order to defend your thesis? Aren't these real and serious events that deserve to be treated with gravity? I don't feel particularly inclined to speak so flippantly about the people who actually did die on June 4th -- incidentally the day before the Tank Man video, which is of him obstructing tanks leaving the square.
