Remember that statement when Hillary or Daschle or some other Dem is in charge and says "Round up all the usual suspects." You or I, nor anyone else for that matter, will be able to say a damned thing when they pick us up as part of "the usual suspects."
Why? Because the precedent has been set. As a result of Padilla's case, the Feds can round up anyone they please, anytime they want, and hold them incognito for as long as they want -- just because the President or some "unnamed source" says that we are suspect.
Welcome to the future.
I hate to be the one to break this to you but the precedent was set in 1942, Ex-Parte Quirin. I'm a blue collar schlub and even I know that.
