Michael Sullivan, the departing director of the Bureau of Alcohol, Tobacco, Firearms and Explosives, says the gang's dependence on shocking violence to advance extortion, prostitution and other criminal enterprises has frustrated attempts to infiltrate and disrupt the insular group's activities.
"MS-13's foothold in the U.S. is expanding," Sullivan says. Kaiser says the street gang is in 42 states, up from 33 in 2005. "Enforcement efforts have been effective to a certain extent, but they (gang members) keep moving," he says.
MS-13 is the abbreviation for the gang also known as Mara Salvatrucha. The group gained national prominence in the 1980s in Los Angeles, where members were linked to incidents involving unusual brutality. [FBI: Burgeoning gangs behind up to 80% of U.S. crime, February 1, 2009
