It is very unlikely—if not impossible—that a guerrilla movement would voluntarily agree to demobilize if the cost is that a majority of its members will receive long prison sentences. For this reason, any peace accord between the Colombian government and the Farc (Revolutionary Armed Forces of Colombia) Marxist guerilla will not be able to adapt to a strict interpretation of the duty to investigate, judge, and penalize. The challenge in this context is to incentivize demobilization while fulfilling the accountability standards of criminal law.
