Caldéron's crusade against drug cartels

Five years ago, Mexican President Felipe Caldéron launched a "crusade against the drug cartels" in a bid to reduce the consumption and trafficking of drugs. Despite these efforts there have been new outbreaks of violence in regions previously protected. One example is Acapulco whose crime rate has increased 350% in just one year. Three months ago, the Mexican government multiplied its efforts to protect its inhabitants, particularly in schools. Laurence Cuviller et Matthieu Comin report.
