A good start, hopefully the "authorities" will expand this effort to include apprehending potential terrorists who are trying to ENTER the country.
Just checked CNN: the Feebies ran them through their handy-dandy Terrorist Computer List ( Acme Terror Finder- $15.95 plus tax )and released them. It is noteworthy that they were released in smaller, more manageable groups: not enough to take over an airplane without weapons.
Adios, muchachos !
