by Bernd Debussman Jr. Mexican drug trafficking organizations make billions each year trafficking illegal drugs into the United States, profiting enormously from the prohibitionist drug policies of the US government. Since Mexican president Felipe Calderon took office in December 2006 and called the armed forces into the fight against the so-called cartels, prohibition-related violence has killed over 12,000 people, with a death toll of over 5,800 so far in 2009. The increasing militarization of the drug war and the arrest of several high-profile drug traffickers have failed to stem the flow of drugs -- or the violence -- whatsoever. The Merida initiative, which provides $1.4 billion over three years for the US to assist the Mexican government with training, equipment and intelligence, has so far failed to make a difference. Here are a few of the latest developments in Mexico's drug war: Friday , October 16 In Michoacan, three bodies were found , all with messages attached. The messages were directed at the Zetas organization, and appear to have been from La Familia. La Familia was once part of the Zetas organization, but the two groups have been fierce rivals since the group split from the Gulf Cartel (and the Zetas) in 2006. In other parts of Mexico, two men were assassinated in Tijuana, and a boy who was jogging was killed after being caught in a firefight between gunmen and the army in Tamaulipas. Five people were murdered in Culiacan, Sinaloa, three in Hermosillo, Sonora, one in Durango, and six in the Ciudad Juarez area. Saturday , October 17 In Tijuana, the nude, mutilated body of a man was found hanging from an expressway overpass. It is the second such discovery found in the last two weeks. Local news outlets reported that the man’s tongue had been cut out, which suggests that drug traffickers suspected he was an informant. Additionally, a gun battle between police and drug traffickers left one police officer dead and two wounded. A suspected cartel member was also killed in the incident. Police recovered five assault rifles and vests with federal insignia from several vehicles used by the gunmen. The day before, the the decapitated body of a woman whose hands and feet had been bound were found in a different part of the city. Monday , October 19 Two people were killed after being ambushed by a group of heavily armed gunmen in Guerrero. One of the dead was a policeman, and the other was a civilian who was riding a bus that was caught in the crossfire. Additionally, five bodies showing signs of torture were recovered from various parts of Acapulco. Attached to each of them were notes threatening “kidnappers, thieves and traitors” and signed by Arturo Beltran-Leyva, the boss of the Beltran-Leyva cartel. 18 people were killed in drug-related killings in Ciudad Juarez. At least 21 other drug-related homicides were reported in Mexico, including nine beheaded bodies found in Tierra Caliente. Tuesday , October 20 In Guerrero, at least three banners were found which threatened police and Genaro Garcia Luna, the Secretary of Public Safety. The signs were signed by what appears to be a new, Guerrero branch of the “La Familia” cartel which is based in Michoacan. The signs also accused Garcia Luna of protecting the Beltran-Leyva cartel and the allied Zetas organization. In another part of Guerrero, the body of a bus driver was found by the side of the road, and showed signs of torture. A second body was found near Acapulco. Near the city of Ciudad Mante, police arrested a man who had 107 kilos of marijuana in a hidden compartment of his pick-up truck. Wednesday , October 21 A suspected member of the Juarez Cartel was added to the FBI’s ten most wanted list. Eduardo "Tablas" Ravelo, 41, is allegedly a high-ranking member of the Barrio Azteca gang. In exchange for a steady supply of narcotics, Barrio Azteca performs enforcement tasks for the cartel on both sides of the border, and can effectively be considered part of the Juarez cartel which operates on American soil. Ravelo is suspected of ordering the killing of another high-ranking gang member, David "Chicho" Meraz, during an internal power struggle. Meraz was killed in Ciudad Juarez last year. Ravelo is reportedly hiding in Juarez under the protection of the cartel. Earlier in the week, another man with suspected cartel connections was also added to the FBI’s ten most wanted list. Jose Luis Saenz, of Los Angeles, is suspected of killing at least four people (including his girlfriend) and is allegedly an enforcer for an unnamed Mexican drug trafficking organization. In October 2008 he shot and killed another gang member in LA County who apparently owed $620,000 to the cartel. Across Mexico, 40 drug-related homicides were reported in a 24-hour period, bringing the 2009 total to over 6,000. Thirteen of these were in Chihuahua, and of these, nine were in Ciudad Juarez. According to a running tally by El Universal, 1,000 people were killed in drug-related violence in Mexico in the last 40 days. The previous 1,000 had been killed over 41 days, and the 1,000 before that in 44 days. Since August 1st, an average of 24 homicides were reported daily, approximately one every hour. One out of every three drug-related homicides was in Ciudad Juarez. Much of the violence is due to the conflict being fought by the Sinaloa Federation and the Juarez cartel over control of the Ciudad Juarez-El Paso drug trafficking corridor.
