The war between Mexico's cartels and law enforcement agencies reached a chilling new height this week. Assassins ambushed the acting chief of Mexico's federal police, Edgar Millan Gomez, as he walked into his apartment in Col. Guerrero in Mexico City early Thursday morning. The papers are saying the Millan Gomez murder is the work of the Sinaloa cartel. Put in perspective, this means violent criminal organizations are engaged in low-grade, pinpointed warfare against the whole Mexican law and order infrastructure -- and they're winning.

Thursday's high-profile assassination throws the country's entire anti-narco effort into a state of uncertainty, while narcotics continue to flow north and the killings go on incessantly. So far 1,000 people have died in the narco war this year alone. It just doesn't stop. It was another bloody week in the Mexican north, with a sex crimes investigator killed brutally in her driveway in Juarez on Monday. And just this morning, gunmen shot and killed a high-ranking federal anti-kidnapping agent, also here in Mexico City.
