What does the FBI think about Bitcoin, in brief? Also related: The context of FBI involvement with Bitcoin

The FBI document regarding Bitcoin that was leaked in May 2012 is very long. Is there a brief summary of the most important points somewhere?
The most interesting part of the document isn't that long, as half of the pages explain some terminology and how Bitcoin works.

The main points made are:


Bitcoin is the world's first decentralised currency, thus it is hard to audit and control it
Bitcoins can become popular among criminals as they offer a lot of anonymity
Bitcoins can be used to commit money laundering
It is very likely that people wanting to steal Bitcoins will target third-party services (such as exchanges), and users' wallets
It is hard to link user's identity to their Bitcoin address, but can be quite easy when they convert their Bitcoins into a fiat currency


There are also a couple other, smaller points made and it is generally a good read. As a side note, the paper appears to have a small mistake on page 4 - listing Bitcoin's lowest price since the bubble as 4$, whereas it was as low as 2$ at some point.
