Lesser of two evils: plunge a country and a region into chaos and civil war (with the associated tens to hundreds of thousands of casualties on all sides) or take out a few innocent bystanders during the apprehension of terrorists?

If we don't have the intelligent gathering capabilities to find terrorists we certainly have no business invading countries now, do we?

Why are we in Iraq when the mastermind of 9-11 is still free?

Gee whiz, Germany managed to put terrorists on trial and find them guilty.

Any person caught breaking U.S. Federal laws has Constitutional rights whether you like it or not. If you don't accept that then you are breaking your oath of service to this nation because you are failing to uphold the Constitution as you are required to do (and part of that Constitution is the Fifth, Sixth, and Eighth Amendments the last time I checked).
