More news from the border

This gives me the willies:

Homeland Security Secretary Tom Ridge met publicly with top Mexican officials last week to discuss border security and smuggling rings that could be used to slip al-Qaeda terrorists into the country. Weeks prior to Ridge's lightning visit, U.S. and Mexican intelligence conferred about reports from several al-Qaeda detainees indicating the potential use of Mexico as a staging area "to acquire end-stage chemical, biological, radiological and nuclear material." U.S. officials have begun to keep a closer eye on heavy-truck traffic across the border. The Mexicans will also focus on flight schools and aviation facilities on their side of the frontier. And another episode has some senior U.S. officials worried: the theft of a crop-duster aircraft south of San Diego, apparently by three men from southern Mexico who assaulted a watchman and then flew off in a southerly direction. Though the theft's connection to terrorism remains unclear, a senior U.S. law-enforcement official notes that crop dusters can be used to disperse toxic substances. The plane, stolen at night two weeks ago, has not been recovered.
