I wish the article would go into more depth about how FinCEN was used to spot Spitzer's transactions. Was it a person scanning the database, or some algorithm the Feds use to identify suspicious transactions? They say that only transactions exceeding $10,000 are entered in the system -- so then how did they see that Spitzer had many suspicious transactions just below $10,000? Pmarca has an a partial transcript of Spitzer's conversations at http://blog.pmarca.com/2008/03/life-lessons-fr.html http://blog.pmarca.com/2008/03/life-lessons-fr.html
