The most serious human rights problems were impunity, an inefficient judiciary, forced displacement, corruption, and societal discrimination. An inefficient justice system subject to intimidation limited the government's ability to prosecute effectively individuals accused of human rights abuses, including former members of paramilitary groups. The availability and influence of drug-trafficking revenue often exacerbated corruption. Societal discrimination against indigenous persons and Afro-Colombians at times restricted the ability of these groups to exercise their rights.Other problems included extrajudicial and unlawful killings; slow pace of investigations, trials, and indictments in cases related to extrajudicial killings; insubordinate military collaboration with members of illegal armed groups; forced disappearances; overcrowded and insecure prisons; harassment and attacks against human rights groups and activists, including death threats and killings; violence against women and girls; trafficking in persons; and illegal child labor.The government continued efforts to prosecute and punish perpetrators of abuses, including members of the security services. It increased resources for the Attorney General's Office, prioritized human rights cases, and employed a contextual analysis strategy to analyze human rights and other cases. Nonetheless, the system generally failed to close out cases quickly and efficiently.Illegal armed groups--including the FARC and the National Liberation Army (ELN), as well as organized crime groups (some of which contained former paramilitary members)--committed numerous abuses, including the following: political killings; killings of members of the public security forces and local officials; widespread use of land mines and improvised explosive devices (IEDs); kidnappings and forced disappearances; sexual and gender-based violence; subornation and intimidation of judges, prosecutors, and witnesses; infringement on citizens' privacy rights; restrictions on freedom of movement; widespread recruitment and use of child soldiers; attacks against human rights activists; and killings, harassment, and intimidation of teachers and trade unionists. Illegal armed groups continued to be responsible for most instances of forced displacement in the country.
