In "Freakonomics", there is an interesting chapter on how the Ku Klux Klan lost its terror potency. Apparently, someone infiltrated the KKK and began to leak out KKK code-words and important meeting decisions to the press (and these were passed around my newspapers and radio stations). Needless to say, this left the KKK discombobulated and they have never been as strong since.
Wonder if we can do something similarly creative to bust open SIMI,etc.
Even if think the above is wishful thinking, I think it's a lot more sensible than saying "All Muslims are terrorists"
