According to members of both the F.B.I. and the Homeland Security Department’s Immigration and Customs Enforcement agency, the government’s policy of deporting illegal aliens belonging to MS-13, the gang named Mara Salvatrucha has been working in the gang’s favor.

…a deportation policy aimed in part at breaking up a Los Angeles street gang has backfired and helped spread it across Central America and back into other parts of the United States. Newly organized cells in El Salvador have returned to establish strongholds in metropolitan Washington, D.C., and other U.S. cities. Prisons in El Salvador have become nerve centers, authorities say, where deported leaders from Los Angeles communicate with gang cliques across the United States.

A gang that once numbered a few thousand and was involved in street violence and turf battles has morphed into an international network with as many as 50,000 members, the most hard-core engaging in extortion, immigrant smuggling and racketeering. In the last year, the federal government has brought racketeering cases against MS-13 members in Long Island, N.Y., and southern Maryland.

Very interesting story, one that indicates the need for a change of policy where dealing with MS-13 members is concerned.

It is certainly bad enough, thanks to our porous borders, that we face a veritable infestation of illegal aliens in the United States –Mustang at Social Sense has a great post on our lax border security situation and the illegal alien problem that continues in a long, highly informed comment thread, well worth checking out — but to be infiltrated also by gangs of violent criminals who make our own domestic gangs seem like weak amateurs is an inexcusable breach of homeland security.
