This maybe slightly off-topic but is it really surprising that the DHS may be concerned regarding money flows through bitcoin?

Just watched Zero Dark Thirty the other day where the CIA tracked down an al-quaida suspect because he transferred 5000$ to another al-quaida member's bank account. Not the smartest move obviously.
Reminded me of bitcoin as it's the perfect tool for almost any illegal activity one can think of.  

If I was responsible for tracking down terrorists and tracking down their donators, bitcoin would piss me off big time.

(btw Zero Dark Thirty is a pretty good movie)
