pay off your CC and get flagged by homeland security

An interesting article here about a couple who paid down a large chunk of debt on their credit card.  Apparently all such transactions are monitored by Homeland Security, and it was blocked until homeland security could investigate them and determine if they were evil people or not.

I wonder what little things we all have done to get on the check em out list.  Even briefly.  It would be interesting and probably scary to learn the answer.  How many people are flagged a day?  How many times has that actually helped us catch or prevent a terrorist act?  Could that have helped stop 9/11 or various other acts?  Would it do anything to stop our own home born terrorists (think Oklahoma).
