The government has broad powers to limit citizens' rights. The government could and did censor the media (from television shows to websites) if it determined that the content would undermine social harmony or criticized the government. The Internal Security Act (ISA) permits preventive detention without warrant, filing of charges, or normal judicial review; in recent years, the government has used it against alleged terrorists and not against persons in the political opposition.The following additional human rights problems were reported: Caning is an allowable punishment for some crimes; restrictions existed on free speech and assembly; government intimidation led to self-censorship by journalists; there were some limited restrictions on freedom of religion; and some restrictions on labor rights.The government prosecuted officials who committed human rights abuses, although there were no instances of such prosecutions reported during the year. There were no reports of impunity involving the security forces.
