Mexican drug trafficking organizations make billions each year smuggling 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 more than 28,000 people, the government reported in August. The increasing militarization of the drug war and the arrest of dozens of 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:

Wednesday, September 15

In Tamaulipas, 22 gunmen were killed during a two-hour gun battle with the army. The incident began when soldiers investigating suspicious activity came under fire. Twenty-five rifles and several grenades were seized during the incident.

In a separate incident, 19 gunmen were killed in a clash with the army in Nuevo Leon.

In Ciudad Juarez, a young photojournalist was shot and killed in a parking lot. Luis Carlos Santiago, 21, worked for the Juarez daily El Diario. He became the second reporter from the paper to have been killed in two years. In 2008, the newspaper's lead crime reporter was shot and killed outside his home. A prosecutor assigned to his killing was also assassinated. A second photojournalist was critically wounded.

On Sunday, El Diario published a front-page editorial directed at the cities drug cartels, asking "What do you want from us?" and said that the cartels had become the de-facto authorities in the city. That prompted strong criticism from the Calderon administration, which said you cannot negotiate with criminals.

Friday, September 17

In Ciudad Juarez, eight people were killed when gunmen opened fire inside a crowded bar just after 4:00am. The seven men and one woman were aged between 20 and 35. The former owner of the bar, Wilfred Moya, was shot and killed at the same location about two years ago.

Sunday, September 19

In Guerrero, the bodies of six police officers were recovered from a ravine. This brings the total death toll from a mass abduction of nine police officers who were taken captive by gunmen in the community of El Revelado to eight. Of the bodies that were recovered Sunday, four were dismembered. A note threatening authorities was left alongside the bodies. No motive or suspects have been announced in the attack.

Monday, September 20

In Ciudad Juarez, authorities released four men who had previously been accused of 55 murders, due to a lack of evidence. The men had been in custody in Mexico City for two months before being returned to Juarez, and are mandated to come to another hearing on Thursday, although they are no longer incarcerated. All four are suspected of belong to the Artist Assassins, a local drug gang which is allied to the Sinaloa Cartel.

Tuesday, September 21

Near Ciudad Juarez, a mob beat to death two alleged kidnappers. Federal police intervened, but the crowd blocked their squad cars and the two men died of their wounds. The town of Ascension, where the incident occurred, has been particularly hard hit by drug-related kidnappings and killings.

Wednesday, September 22

A Ciudad Juarez newspaper editor has been given asylum because of threats against his life in Mexico. Jorge Luis Aguirre is the editor of the online newspaper La Polaka. Last year, he testified to the Senate Foreign Relations Committee about his experiences as a journalist in Mexico. More than 30 journalists have been killed or have vanished since 2006.

Total Body Count for the Week: 187

Total Body Count for the Year: 8,049
