The FBI has also created a virus to get around PGP. An email goes through the backdoor of your computer (I don't know what the F--k the backdoor is but it's compurter lingo), then it is able to record all of your keystrokes and secretyly email them to the feds. This allows them to record your keystrokes when you type your password into PGP. If you are using keys it can also go into PGP and send the keys to them.
This is expensive and time consuming and they use it to go after much bigger fish than someone buying a few bottles of test and deca. It just shows that even with the most up to date encryption technology the feds can pretty much any info they need.
