One of the frequent claims from supporters and profiteers of illegal immigration is that illegal aliens are just here to work, and no Mexicans/Central Americans have been involved in terrorist attacks. First, that's false: two of the 9/11 hijackers were able to get Virginia driver's licenses with the assistance of an illegal alien from El Salvador.

And, one illegal alien was even willing to help provide fake ID that he was told was for Khalid Sheikh Mohammed (KSM):

An "admitted illegal alien from Mexico" was arrested Wednesday for producing a half-dozen fake identification, Social Security and permanent residency cards and selling them to undercover police officers, the Butler County [Ohio] Sheriff's Office said Thursday.

Abel Gaston Gudino-Arenas, 33, of Middletown, was charged with six counts of forgery — a fifth-degree felony — and no operator's license — a misdemeanor — for manufacturing fake documents, according to a news release from the sheriff's office. Deputies said the man admitted to manufacturing the cards for more than three months.

Gudino-Arenas was arrested after he allegedly delivered a fake ID to undercover officers for Khalid Sheikh Mohammed of Pakistan, the self-proclaimed mastermind behind the Sept. 11, 2001, terrorist attacks. According to the news release, officers asked Gudino-Arenas to produce the ID for Mohammed "in an attempt to see how far (he) was willing to go."
