Loose lips lead to arrest:

Federal agents met a Southwest Airlines flight at the Raleigh-Durham International Airport and arrested 11 male passengers suspected of illegally entering the United States, authorities said Wednesday.

The 11 men boarded their flight Tuesday by showing federal agents one form of identification -- a Mexican voter registration card that contained a name, age and photo, said Thomas O'Connell, resident agent in charge of U.S. Immigration and Customs Enforcement in Raleigh.

Southwest Airlines spokeswoman Marilee McInnis said the incident was the first time that she knew of that immigration agents boarded a Southwest flight to check passenger identification.

The events leading to the men's arrest began when an air marshal observed a group of men on a flight from Las Vegas to Chicago, O'Connell said. The marshal overheard the men discussing how they were smuggled into the United States.

Good for the air marshalls on this one, but bad for airline security. Read that second graph again--how did the illegals get on that plane? By presenting a "Mexican voter registration card that contained a name, age and photo." That should not be sufficient ID to board a plane in the post-911 United States. And yet it is.

Chances are, by the way, that the "voter registration card" in this story is actually a matricula consular card. Those cards are issued by the Mexican government to...well...just about anyone:

“Federal officials have discovered individuals from many different countries in possession of the matricula consular card. … At least one individual of Middle Eastern descent has also been arrested in possession of the matricula consular card. The ability of foreign nationals to use the matricula consular to create a well-documented, but fictitious, identity in the United States provides an opportunity for terrorists to move freely within the United States without triggering name-based watch lists that are disseminated to local police officers. It allows them to board planes without revealing their true identity.”—McCraw, FBI

As we've now seen demonstrated conclusively.
