After the 1953 coup, the Shah's government formed the SAVAK (secret police), many of whose agents were trained in the United States. The SAVAK monitored dissidents and carried out censorship. After the 1971 Siahkal Incident, it was given a "loose leash" to torture suspected dissidents with "brute force" that, over the years, "increased dramatically", and nearly 100 people were executed for political reasons during the last 20 years of the Shah's rule. Nevertheless, the Shah generally dealt with dissent in a relatively mild manner compared to most autocratic leaders. After the revolution, SAVAK was officially abolished, but was in reality "drastically expanded" into a new organization that killed over 8,000–12,000 prisoners between 1981 and 1985 alone, and 20,000–30,000 in total, with one prisoner who served time under both the Shah and the Islamic Republic declaring that "four months under (Islamic Republic's) warden Asadollah Lajevardi took the toll of four years under SAVAK".
