Mexican Drug War became the starting point of the war between the government and the drug cartels. Calderón escalated his anti-drug campaign, in which there are now about 45,000 troops involved in addition to state and federal police forces. In 2010 Calderón said that the cartels seek "to replace the government" and "are trying to impose a monopoly by force of arms, and are even trying to impose their own laws." As of 2011, Mexico's military captured 11,544 people who were believed to have been involved with the cartels and organized crime. In the year prior, 28,000 individuals were arrested on drug-related charges.
Chief of police sheriff is the chief of a county law enforcement agency. Although sheriffs are not usually counted as police chiefs, their agencies usually have the powers and role of a police department. Some sheriffs' agencies are limited to non-policing matters such as courtroom security. The usual difference between a sheriff and a police chief is that sheriffs are elected (except in New York City, Rhode Island and Hawaii) and responsible for a county whereas a police chief manages law enforcement in a city or town and is appointed by its local government.
