Yes, Bourne, she was behind for the first 3 parts of the race. An Austrialian (the previous world record holder... don't remember her name) was ahead.
Then she made the turn into the freestyle with the force of Michael Phelps, took a small lead, and swam the freestyle leg in a little over 58 seconds. Just absurd.
I don't believe in circumstantial evidence. I also feel that the IOC does a pretty good job of testing (although didn't Marion Jones get away with it for a while?), so I'd like to give the kid the benefit of the doubt. But it's really tough, given that China's Olympians have a history of cheating, and she's only 16.
