As in several other cases since 9/11, it was alert private citizens who notified the Department of Homeland Security of Mullawala's suspicious behavior. (They will no doubt be labeled Islamophobes and bigots by the usual grievance-mongering mob.)

And once again, it was enforcement of immigration laws that played a critical role in detaining him. Like some of the 9/11 hijackers and several al Qaeda operatives identified in the United States over the past decade, Mullawala was here on a temporary student visa that he had overstayed.

Must I remind you that the 9/11 hijackers obtained some 364 separate pieces of identification, including driver's licenses, in order to conduct their murderous business? Hijackers Hani Hanjour and Khalid Almihdhar conspired with illegal alien day laborers at a Falls Church, Va., 7-Eleven to obtain government-issued photo IDs. Three other hijackers obtained IDs at an Arlington, Va., DMV.

Terrorist truck bombs have killed hundreds of Americans in Beirut, at the Khobar Towers, and Iraq. For the operatives behind the wheel, a license to drive is a license to kill. Over the past two years, the FBI has put law enforcement officials on high alert for U.S.-based operatives connected to al Qaeda who may be in possession of commercial driver's licenses and may be planning to use truck bombs.

In Boston, suspected al Qaeda agent and illegal alien Nabil al-Marabh obtained a license permitting him to drive semi-trucks containing hazardous materials, including explosives and caustic materials.

In Minneapolis, suspected al Qaeda operative Mohamad Elzahabi, who obtained a green card through a fake marriage, was able to obtain a commercial driver's license to drive a school bus and to haul hazardous materials -- despite FBI knowledge that Elzahabi had been tied to terrorism.

Earlier this year, more than 200 Somalian and Bosnian immigrants illegally obtained Missouri commercial driver's licenses or certifications to handle hazardous materials through a West Plains truck-driving school that had a contract with the state, according to federal prosecutors. In just a few short weeks, Democrats led by Nancy Pelosi -- a staunch opponent of strengthened ID laws and strict immigration enforcement -- will reassume power in Washington. An open borders-friendly White House has expressed willingness to deal with them. So we know who supports illegal alien workers and potential terrorist drivers waiting for amnesty. But who will stand up for us?
