For every story I hear about "Police disrupt criminal plan to ..." I hear a hundred about "Police are investigating < fill-in-the-blank crime> committed yesterday...".
If one of them commits a crime or even conspires to commit a crime, they can be imprisoned.
That certainly worked well with Mohammad Atta and his Merrie Band, didn't it?
Perhaps you're planning on hiring John Anderton to do this "good police work". You might want to sign up the Tooth Fairy, too.
And afterwards, we can all have milk and cookies.

No, it didn't. But, good police work is what we need to take down the violent Muslims in the US. What you are advocating (the identification and incarceration of millions of law-abiding citizens solely for their religious affiliation) is illegal, immoral, counterproductive, and impractical. If you can't see that, I'm wasting my time even discussing it.
And to the other FReeper who mentioned our incarceration of hundreds of thousands of Japanese in WWII--that was reprehensible, too. Those poor Japanese were wrongly held for something they had absolutely no control over--their ethnic heritage.
