Secret police forces are typically associated with totalitarian regimes, as they are often used to maintain the political power of the state rather than uphold the rule of law. Instead of enforcing the law as ordinary police agencies, the secret police organizations are endowed, sometimes officially, to operate beyond and above the law. Secret police forces are accountable only to the executive branch of the government, sometimes only to a dictator. They operate entirely or partially in secrecy, that is, most or all of their operations are obscure and hidden from the general public and government except for the topmost executive officials. Secret police agencies have often been used as an instrument of political repression.
