Yesterday in Mexico, drug lord Marcos Arturo Beltrán Leyva was shot dead by navy personnel during a raid on a luxury apartment complex near Cuernavaca. Known as “The Boss of Bosses,” Beltrán Leyva had always been on the radar of president Felipe Calderón, who even approved a $2.4 million bounty. And back in August, U.S. Attorney General Eric Holder announced a federal indictment against the drug lord for smuggling billions of dollars worth of cocaine across the U.S./Mexico border. After this slow ratcheting up of pressure, Calderón finally made the move to apprehend Beltrán Leyva after the severed heads of five police officers and a prosecutor were found in streetside garbage Wednesday morning by sanitation workers in the state of Durango. President Calderón is touting the Beltrán Leyva killing as a success in his much-publicized drug war, which many observers had seen as little more than a highly destructive standoff. But even in the afterglow of yesterday’s events, government officials admit that unless the U.S. demand for cocaine diminishes, Beltrán Leyva simply represents the latest in a long line of drug lords.
