I've researched BTC laundering, because I'm too curious to live. The main method of doing it is via "mixers", servicss that distribute your BTC among hundreds of accounts, and then pay you back (minus a small fee) via hundreds of other accounts. Theoretically, it's impossible to track a single payment through such a process, since the BTC paid back isn't the BTC paid in. Another possible security measure woukd be the use of multiple accounts, allowing legitimate purchases and purchases involving physical locations to be separate from illegitimate buys. The main weak point is your location; once a physical object is shipped to you, it's real easy to tie that to your illicit BTC wallet, and from there, you're hosed.
