The wave of violence in Mexico is becoming even more gruesome. Twelve bodies of federal police officers were found on the side of a remote highway in Michoacán, Mexico, with signs of torture. The ambushed officers were apparently killed execution style, with single shots to the head. The killings are the latest in violence spurred by President Felipe Calderón's declaration of war on the drug cartels in 2006, which has since led to the deaths of almost 10,000 people. In the past month, 13 other bodies have been found along the same stretch of highway, and 16 police officers were wounded over the weekend in Michoacán, with at least 32 people killed in the past few days.
