From the Wash Times link above re: al-Qaeda and the Americas -
"Although they are actively involved in alien, drug and weapons smuggling, Mara Salvatrucha members in America also have been tied to numerous killings, robberies, burglaries, carjackings, extortions, rapes and aggravated assaults including at least seven killings in Virginia and a machete attack on a 16-year-old in Alexandria that severely mutilated his hands.
The Salvadoran gang, known to law enforcement authorities as MS-13 because many members identify themselves with tattoos of the number 13, is thought to have established a major smuggling center in Matamoros, Mexico, just south of Brownsville, Texas, from where it has arranged to bring illegal aliens from countries other than Mexico into the United States"
Now you know that these are just honest hard working illegal aliens. Please, let's not confront this reality. I'm too fragile. ;-)
