More than 12,000 people have died this year as a result of Mexico's drug prohibition war, although officials said the number could be higher. Through November 30, 12,456 people were killed, making 2010 the deadliest year since Mexican President Felipe Calderon began a government crackdown against traffickers in 2006. In a recent survey, 59 percent of respondents said organized crime groups are winning the drug prohibition war against federal forces; a different poll said 80 of the respondents believe there is more violence in Mexico than a year ago.
