 There are an estimated 150,000 personnel in the PSO.
 The Central Security Organization, which is part of the Ministry of Interior, maintains a paramilitary force and also has its own extrajudicial detention facilities.
 Also attached to the Ministry of Interior is the Criminal Investigative Department (CID) of the police, which conducts most criminal investigations and arrests.
