Courtesy of POAC, I came across this story:
Homeland Security Investigates 'Unusual' Credit Card Payments
That's right, you didn't read that wrong. PAYMENTS, not charges. I'm interested in hearing any possible explanations for how a large credit card payment is any kind of security risk. I wasn't sold on being sent to the long security line if someone else buys your plane ticket for you, because apparently al Qaeda and your parents have that in common.
Really.
