So, 19 foreign hijackers infiltrate America, take flying lessons, and murder 3,000 people. And nearly four years later, illegal aliens are still able to enroll in U.S. flight schools and leave the country without getting caught:

ATLANTA, Georgia (CNN) — An anti-terrorism task force headed by the FBI has issued a special alert bulletin concerning a man who authorities said took flight lessons while in the United States illegally.

The man, Zayed Christopher Hajaig, has been located in the United Kingdom, said Steve Emmett, a special agent with the FBI in Atlanta. Hajaig has not been taken into custody, Emmett said, but the U.S. Federal Aviation Administration has been alerted, and his name has been placed on a “no-fly” list.

The Atlanta Joint Terrorism Task Force — a special anti-terrorism unit of local law enforcement and federal authorities — issued the bulletin Thursday night. Hajaig took lessons at a flight school near Atlanta in Gwinnett County, Emmett said.

Someone from the school alerted authorities when Hajaig attempted to have his instructor upgrade his flight rating when he wasn’t yet qualified, he said. Emmett also said Hajaig attempted to have the flight school accelerate his training schedule.

“All flight schools after 9/11 have been asked to increase their state of alertness,” Emmett said. “They’ve been asked to report any suspicious behavior.”

Behavioral profiling? Shhhhh. Don’t tell the ACLU.
