Having spent 3 years in Central America as an officer in U.S. Army Special Forces, I can assure you the Mara Salvatrucha are indeed a group to be very concerned about. We trained Salvadorian officers to be the most efficient killers in the history of modern war-fare. The young enlistees only knew about war as children and they wanted the Russians & Cubans expelled from their country. The U.S. Army provided these soldiers with Green Cards since they had served under the direction of U.S. Special Forces. These trained killers were then allowed into the USA. While assuming America would reward them for expelling Communism from our hemisphere, these soldiers found a country that had little interest in their accomplishments. Many turned to criminal behavior with the same fervor they had for mutilating the enemy. These guys are absolutely ruthless. Tha Savadorian Army paid these guys a bounty. It did not matter who they killed, as long as they could produce a corpse, they got paid. Trust me, American law enforcement officials will not be able to thwart the Mara Salvatrucha from achieving their goals of linking up with the Colombian Mafia, Mexican Mafia or whatever group has the money to pay these American-trained professional killers. The Congress of the United States financed the entire operation in El Salvador and now their naive efforts are biting them in the ass. Good job!
