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 5,000 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:

Twenty-three people were killed in drug-related violence in the state of Chihuahua. Eight of these killings occurred in the capital city of Chihuahua, and 12 occurred in Ciudad Juárez. In Chihuahua, four men and a teenager were killed when the vehicle in which they were traveling was ambushed by a group of gunmen. In another part of the city, an eight-year old boy was killed after being hit by a stray bullet. Among the dead in Ciudad Juárez was a woman who was badly burned after an explosive device went off in the brothel in which she was thought to work.

An army officer and six gunmen were killed in two separate gun battles in Zacatecas and Michoacan. In Zacatecas, the army repelled an attack by gunmen, killing five and capturing eight. They also seized five vehicles, weapons, clothing and food. In Michoacan, an army officer was killed after a military convoy was ambushed by gunmen in a hillside community. Two other people were killed in drug-related violence in Michoacan, six in Ciudad Juárez, and one in the greater Mexico City area.

At the Calexico, CA border crossing, authorities seized more than 6,000 pounds of marijuana hidden in a shipment of door knobs. Dogs alerted officers to the truck in which more than 458 wrapped packages of marijuana were found. A 30-year old Mexican national was taken into custody.

In Tijuana, three men were shot and killed by suspected cartel gunmen wielding AK-47s. The killings came just hours after a firefight between soldiers and drug traffickers at a gas station left one soldier wounded in the foot. In another part of Baja California, six men were arrested on suspicion of being tied to a known drug trafficker, Raydel Lopez Uriarte, aka "El Muletas" ("crutches").

Seven people were killed in Chihuahua, six of whom were killed in Ciudad Juárez. One of the murders occurred just feet from soldiers that were guarding the city's main plaza, where national security officials were meeting to analyze drug-related violence. In Chiapas, an anti-mining organizer was killed by a gunman on a motorcycle. Mariano Abarca was head of the Mexican Network of Communities Affected by Mining.

In Reynosa, police rescued a US citizen who had been kidnapped a week earlier in McAllen, Texas. Raul Alvarado, 36, was forced into a vehicle at gunpoint and taken to a safehouse in Reynosa, where he was bound and beaten. His abductors demanded a ransom of $30,000 and two luxury cars. It is unclear if any ransom was paid. There has been an increase in kidnappings on the US side of the border, most of them linked to illegal activity.

In Mexico City, a protected state witness was gunned down in a Starbucks. Edgar Enrique Bayardo, a former federal policeman, was killed by two gunmen wearing dark suits. His bodyguard was seriously injured in the attack, and a customer at a nearby table was also wounded. Bayardo was arrested last year on suspicion of being employed by the Sinaloa Cartel. Bayardo, whose lavish lifestyle raised suspicion, was made a state witness under the protection of the attorney general's office. He had apparently been followed by gunmen for several days, and it is unclear why he was not better protected or out in public.

Wednesday, December 2

In the Ciudad Juárez area, nine suspected assassins were arrested in an operation carried out by the army. The men are all suspected of working for El Chapo Guzman's Sinaloa Cartel and its enforcement arm, La Linea.

Total Body Count for the Week: 144
Total Body Count for the Year: 6,882
