On 13 May 2002 , judge Cecilia Polack Boluarte issued warrants for the arrest of 11 senior army officers who participated in the raid . The warrants allowed the accused to be held for 15 days before formal charges were filed . The judge 's decision provoked an outcry ; the ministers of defense , justice and the interior all criticized the arrest orders . However , Attorney General Nelly Calderón supported the measure . In a statement made on 20 May 2002 , to Radio Programas del Perú ( RPP ) she said , " We prosecutors are supporting the action taken by prosecutor Saavedra , because he has done a careful investigation ( and ) unfortunately the evidence suggests culpability . That evidence has to be collated to determine what degree of responsibility each arrested officer bears . " On 16 May 2002 , two amnesty proposals were announced in congressional committees , one submitted by the American Popular Revolutionary Alliance party ( APRA ) of former president Alan García , the other by the National Unity party ( UN ) . The UN bill " granted amnesty " to army General José Williams Zapata , who headed up the operation , and to the " official personnel who participated in the freeing and rescue of the hostages . " Human rights organizations such as Human Rights Watch ( HRW ) strongly protested the move . " The successful rescue of the hostages turned these commandos into national heroes , but the evidence of illegal killings is compelling . National gratitude is no reason for shielding them from justice . " the organization argued in a press release . HRW argued that the amnesty proposals clearly conflicted with the principles enunciated by the Inter-American Court of Human Rights in its March 2001 ruling against the Peruvian government in the case of the 1991 Barrios Altos massacre . In that case , which involved the amnesty law passed in 1995 by the Fujimori government , the Court declared the amnesty null and void because it conflicted with Peru 's human rights treaty obligations ; it later interpreted that ruling as applicable to all similar cases
