Peru's Truth and Reconciliation Commission determined that the group [the Tupac Amaru Revelutionary Movement] was responsible for 1.5% of the deaths investigated. In its final findings published in 2003, the Commission observed:

Unlike Shining Path, and like other armed Latin American organizations with which it maintained ties, the MRTA claimed responsibility for its actions, its members used uniforms or other identifiers to differentiate themselves from the civilian population, it abstained from attacking the unarmed population and at some points showed signs of being open to peace negotiations.

Nevertheless, MRTA also engaged in criminal acts; it resorted to assassinations, such as in the case of General Enrique López Albújar, the taking of hostages and the systematic practice of kidnapping, all crimes that violate not only personal liberty but the international humanitarian law that the MRTA claimed to respect.

It is important to highlight that MRTA also assassinated dissidents within its own ranks.[2]
