I'm honestly not sure, but I was under the impression that bitcoin wasn't really anonymous. All transactions are publicly logged to prevent double spend, so you can trace a coin from the first time it was used. If you happen to know that an address maps to a specific someone, you can begin to create a pretty identifiable picture.

See, eg: https://bitcointalk.org/index.php?topic=241.0

I thought this too, but after looking into it I understood how it could be used anonymously: http://www.jefftk.com/news/2013-01-28
