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:

Friday, December 4

Near Monterrey, a group of more than 20 gunmen attacked a police detention center and freed 23 inmates. Two federal officers were killed during the attack. Witnesses reported that the inmates were driven away in at least five vehicles. Earlier on Friday in Monterrey, clashes between the army and dozens of gunmen left 13 people dead -- 12 suspected cartel members and one civilian.

The clashes began when soldiers came under fire as they raided a ranch where hostages were thought to be kept. A firefight ensued between the soldiers and an estimated 50 gunmen, seven of whom were killed and nine captured before the rest managed to escape. The gunmen that escaped later ran into another unit of soldiers, and five of them were killed in the gun battle that followed. A civilian was also killed in the crossfire. Several of the dead gunmen were ex-cops suspected in the death of a municipal police chief who was murdered in November.

Saturday, December 5

Thirty-six people were killed in drug-related violence across Mexico, including five federal agents. Additionally, a public security official in Chihuahua was kidnapped by gunmen as he drove on a highway, and remains to be found. Of the dead, 14 were murdered in Chihuahua, eight of them in Ciudad Juarez. Near Culiacan, Sinaloa, a state police official was found dead (along with an unidentified woman) in a bullet-riddled car. A three-year old who was in the backseat survived. In Guerrero, three policemen and two gunmen were killed in a firefight.

Tuesday, December 8

With the late night killings of four youths in Ciudad Juarez, the total body count this year from Mexico's drug war passed the 7,000 mark. In a 24 hour period, 13 people were killed in Ciudad Juarez, three in Sonora, seven in Guerrero, four in Sinaloa, and four in Mexico City and the surrounding area, bringing the yearly total to 7,026. Of these, 2,991 took place in Chihuahua, mostly in Ciudad Juarez.

Wednesday, December 9

In a report released Tuesday, Amnesty International blasted the conduct of Mexican government forces as they fight against drug traffickers. The report cited five cases involving 35 people that the organization thought were representative of the rampant human rights violations in Mexico, and accused the army of torturing civilians, capturing suspects illegally, and killing prisoners. The report was especially critical of Mexico's civilian authorities, who have refused or failed to investigate allegations of abuse on the part of the army. Complaints against the army are handled entirely by the Mexican military justice system, and out of the thousands of complaints, only a few have been investigated.

In Hermosillo, several locations were attacked in coordinated grenade attacks, leaving four people wounded. In Nogales, near the border with Arizona, five people were executed by gunfire in what appears to be an attempt to take over the local drug trafficking corridor. In Chihuahua, ten people were found murdered, eight of them in Ciudad Juarez.

Total Body Count for the Week: 174

Total Body Count for the Year: 7,056
