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 16,000 people, with a death toll of over 7,000 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, January 22

At the Otay Mesa border crossing near San Diego Border Patrol officers seized 708 pounds of marijuana hidden under a truckload of white sea bass. A 34-year old Mexican national was taken into custody.

In Sinaloa, police discovered the body of a man who had been tortured and strangled. The letter "H" had been carved into his chest with a knife. It is unknown to what or whom this refers. Police believe this may be related to an incident which occurred last week, in which three dead bodies were arranged to form the letter "H". At least five other drug-related homicides occurred in other parts of Sinaloa, and one in Queretaro.

In Durango, a federal police official was shot dead and another was wounded after being ambushed by gunmen. Four people were killed in Ciudad Juarez, and one police officer was wounded after attempting to stop an assault.

In Chihuahua, a gunfight ensued after a Cessna aircraft flown by drug traffickers was forced to land by a police helicopter. After being forced to land, several men who were in the Cessna opened fire on the helicopter, wounding the pilot, who managed to safely land the helicopter. The men who were on board the Cessna managed to escape. 200 kilograms of marijuana were found in the Cessna, and the pilot and passengers on board the police helicopter were later rescued by elements of the Mexican Army. The incident took place in a remote area of the state where there are no roads, and which is known for the cultivation of marijuana and poppy plants.

In other incidents, 12 people were killed in Chihuahua, seven of them in Ciudad Juarez. Eight people were killed in Baja California, and another eight were killed in Sinaloa. A minor was killed in Durango.

Monday, January 25

In the town of Doctor Arroyo, in Nuevo Leon, six people were killed in a gun battle between soldiers and suspected cartel gunmen. Two of the dead were soldiers, and the other four were gunmen. The firefight began when an army patrol came under fire. Three of the gunmen were killed inside a home and the fourth was killed in a vehicle. Additionally, in Veracruz, the body of a court official that had been missing was found dead. A note was left with the corpse, which is indicative of a drug-related murder.

Tuesday, January 26

In Tijuana, four men were killed in various incidents in different parts of the city. In the first incident, 41-year old Cipriano Medina was shot dead by gunmen wielding assault rifles. At least 33 spent shell-casings were found on the scene. In another incident, two men, aged 22 and 30, were gunned down with automatic weapons. At least 90 people have been murdered in Tijuana so far this year.

Total Body Count for the Week: 162

Total Body Count for the Year: 602

Total Body Count for 2009: 7,724

Total Body Count since Calderon took office (December, 2006): 16,807
