Generally, disarmament, demobilization, and reintegration (DDR) programs and truth commissions have operated independently of one another. This has resulted in missed opportunities for strengthening DDR and truth commissions. DDR’s reintegration aims may be furthered by increased truth-telling, and from the perspective of truth commissions, ex-combatants are often key witnesses. Aggregated data from DDR programs can also aid in documenting the larger causes and patterns of violence.
