The human rights situation in Singapore remains a cause for concern. Although the rights to free speech, peaceful assembly and association are constitutionally guaranteed, the government continues to impose restrictions in the name of security, order and public interest. Religious practice is allowed as long as it does not violate any other regulations, and most groups worship freely. However, religious actions perceived as threats to racial or religious harmony are not tolerated. Academics do engage in political debate, but their viewpoints rarely deviate from those of the government on matters related to the country. The Societies Act requires that organisations of more than ten people register with the government, and only registered parties and associations may engage in an
organised political activity. Political speeches are tightly regulated. Although citizensâ€™ right to privacy is generally respected, the Internal Security Act and the Criminal Law Act permit warrantless searches and arrests if national security, order or public interest are perceived to be under threat. Meanwhile, ethnic Malays continue to lag behind ethnic Chinese or Indians in terms of education and income levels, and they reportedly face discrimination in employment. What is more, Singapore continues to sentence people, including foreign nationals, to death for a number of crimes (particularly drug-related ones) and is amongst the countries with the highest execution rates compared to the number of citizens. In 2011, at least four people were hanged according to Amnesty International.
