Citizens did not have the ability to change their government. The government subjected citizens to rigid controls over many aspects of their lives, including denial of the freedoms of speech, press, assembly, association, religion, movement, and worker rights. The government operated a network of political prison camps in which conditions were often harsh, life threatening, and included forced and compulsory labor.Defectors continued to report extrajudicial killings, disappearances, arbitrary detention, arrests of political prisoners, and torture. The judiciary was not independent and did not provide fair trials. There were reports of female victims of trafficking among refugees and workers crossing the border into China. Forced labor was practiced domestically, through mass mobilizations and as a part of the re-education system. NGOs noted that DPRK foreign contract workers also faced conditions of forced labor.The government made no known attempts to prosecute officials who committed human rights abuses. Impunity was a widespread problem.
