Since President Felipe Calderón launched a crackdown against cartels in 2006, more than 28,000 alleged criminals have been successfully killed. Of the total drug-related violence 4% are innocent people, mostly by-passers and people trapped in between shootings; 90% accounts for criminals and 6% for military personnel and police officers. In October 2007, President Calderón and US president George W. Bush announced the Mérida Initiative, a plan of law enforcement cooperation between the two countries.
