Later , some members of Grupo Colina were put on trial . Fujimori signed a controversial law that granted amnesty to anyone accused of , tried for , convicted of , or sentenced for human rights violations that were committed by the armed forces or police . When a court found this law unconstitutional , Fujimori signed a new law removing the right of judicial review over amnesty laws . This second law was known as the " Barrios Altos Law " because it ensured that those members of Grupo Colina who committed the Barrios Altos massacre would be freed . Eventually , the Inter-American Court of Human Rights struck down both amnesty laws
