El Salvador is a constitutional multi-party republic. In 2009 voters elected Carlos Mauricio Funes Cartagena of the Farabundo Marti National Liberation Front (FMLN) as president for a five-year term in generally free and fair elections. Free and fair legislative assembly and municipal elections took place in March 2012. Authorities failed at times to maintain effective control over the security forces. Security forces committed human rights abuses. The principal human rights problems were widespread corruption; weaknesses in the judiciary and the security forces that contributed to a high level of impunity; and abuse, including domestic violence, discrimination, and commercial sexual exploitation against women and children. Other human rights problems included isolated unlawful killings and cruel treatment by security forces; lengthy pretrial detention; harsh and life-threatening prison conditions; some restrictions on freedom of speech and press; trafficking in persons; and discrimination against persons with disabilities and persons with HIV/AIDS. There was also widespread discrimination and some violence against lesbian, gay, bisexual, and transgender (LGBT) persons. Child labor and inadequate enforcement of labor laws also were problems. Impunity persisted despite the government taking steps to dismiss some officials who committed abuses in the penitentiary system and within the police force.
