A sweeping federal takedown confirms that Mexican drug cartels have penetrated the United States and have affiliated drug gangs in hundreds of American cities

A total of 678 gang members from 168 cities were arrested by an Immigration and Customs Enforcement (ICE) task force targeting gangs with ties to drug trafficking organizations. More than 46% of those arrested were affiliated with 13 different Mexican drug trafficking organizations, ICE officials said. Of the 678 arrested, 447 were charged with criminal offenses and 421 were foreign nationals. The operation, Project Southern Tempest, was conducted from December 2010 through the end of February 2011. In addition to the arrests, the operation also seized firearms, large quantities of methamphetamine, cocaine and marijuana, and more than $70,000 in cash, according to ICE officials. Transnational gangs are not only working the drug trade, but are frequently working in human smuggling, weapons smuggling and other crimes with a nexus to the border. One criminal arrested was Rodimiro Burquez-Cortez, a Mexican national and Surenos gang member who was deported once, but re-entered the country and now faces narcotics and weapons charges. His criminal convictions include illegal re-entry, assault, DWI, carrying a concealed weapon and drug possession. Another suspect arrested in the sweep, Shawn Allison, a Jamaican, is a member of the Jamaican Posse whose rap sheet includes convictions for possession with intent to distribute and criminal contempt, according to ICE. Now Allison faces an even more serious charge: attempted murder.
