"Guatemala, a small, impoverished nation, is setting a commendable example by confronting institutionalized corruption in a region where it is widespread. Rooting out the type of graft that has become business as usual in much of the region is vital to attracting foreign investment, creating more equitable prosperity and restoring the trust of citizens in their governments.The remarkable evolution of Guatemala’s criminal justice system began a decade ago when the United Nations established the International Commission Against Impunity in Guatemala, a team of foreign experts who provide technical expertise and political cover to local authorities pursuing complex, high-profile investigations. While the backing of international experts has proved to be transformational, dismantling a culture of impunity will ultimately require empowered civil society organizations and political will.
