Well, let's see:
You can no longer depend on privacy when you telephone your middle-east co-conspirators.
You can no longer board a plane with your box cutter.
You can no longer depend on the CIA and FBI to fail to share information, should they happen to have something incriminating on you.
If you are a non-American committing an act of war on the U.S. overseas, you can no longer count on a trial in the U.S.
Lots of liberties you lost!
