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
