June 5 however, saw one last act of defiance: a solitary man who placed himself in the way of a row of tanks, as if -- with nothing but his skinny body and two shopping bags -- he might take on the entire military. The tanks tried to reroute around him, but he stepped back into their line and continued to block them. He climbed onto the first tank and knocked against its hull -- in an act at once staggeringly defiant and yet oddly pleading. Then he disappeared into the crowd, never to be identified. Twenty years later, the impact of his actions remains as uncertain as his name.
Even 20 years later, it remains like that man we all remember, known everywhere and yet unknowable.
