You can try to get some information from the google cache: www.google.com/search?q=site%3Ahttp%3A%2F%2Fbitcoinpolice.org
blockchain.info contain great information about who/where/when/how.
But, probably no one, except Security Services, can get all of information about credits, who got bitcoin on one place, who spent bitcoin on other.
Plus, if we start to look at the distribution of the markets and popularity of bitcoin, and keep in mind, that Credit Card fraud are still alive, then anybody can get anonymously great amount of bitcoins and anonymously transfer it to any Earth's point.
We discussed for the best way for terrorists to get money.
Mining of bitcoin is not a best way for terrorists to get money, but to transfer, its looks like greatest one. (1 hour = 6 confirmations, and one terrorist have completely paying another for service)
Anyway google will help you to get more information.
And don't forget to looking for same question:
Can my transactions be traced back to me even if I do this?
