If you want proof that this is never going to work, do a search for "HSPD-6 terrorism nexus criteria." There are so many fingers in the pot that this program can't possibly function properly.

From the FBI, a bunch of hogwash:

"TSC (Terrorist Screening Center) is leading significant improvements in counterterrorism information sharing among federal, state, local, and international agencies by distributing information about encounters with known or suspected terrorists reported to its 24/7 call center."

"The TSC has no authority to conduct intelligence collection or other operations. The TSC does not collect intelligence, but only receives identity information collected by other governmental entities authorized by law to do so, with their own policies and procedures to protect privacy rights and civil liberties. The TSC maintains information on known or appropriately suspected terrorists only; it does not maintain information on persons who have no nexus to terrorism."
