This document discusses how the extradition of 18 paramilitary leaders from Colombia to the US has obstructed investigations into human rights violations in Colombia. It notes that no agreements exist between Colombia and the US to guarantee victims' rights to truth, justice, and reparation. The Colombian "Justice and Peace" process, which offers reduced sentences for paramilitary confessions, has stalled with only 4 of the 18 extradited paramilitaries continuing their testimonies. The extradition has served as a further means for impunity in Colombia.
