Boston street gang linked to al-Qaeda cells

This is why we need to secure the southern border:

A burgeoning East Boston-based street gang made up of alleged rapists and machete-wielding robbers has been linked to the al-Qaeda terrorist network, prompting Boston police to "turn up the heat" on its members, the Herald has learned. MS-13, which stands for La Mara Salvatrucha, is an extremely violent organization with roots in El Salvador, and boasts more than 100 "hardcore members" in East Boston who are suspected of brutal machete attacks, rapes and home invasions. There are hundreds more MS-13 gangsters in towns along the North Shore, said Boston police Sgt. Detective Joseph Fiandaca, who has investigated the gang since it began tagging buildings in Maverick Square in 1995. In recent months, intelligence officials in Washington have warned national law enforcement agencies that al-Qaeda terrorists have been spotted with members of MS-13 in El Salvador, prompting concerns the gang may be smuggling Islamic fundamentalist terrorists into the country. Law enforcement officials have long believed that MS-13 controls alien smuggling routes along Mexico.

Illegal immigrants and drugs, while bad for America, are not the most dangerous things that can slip across the Rio Grande.
