Thousands of people are persecuted,tortured and oppressed each day. And most of the time,perpetrators can feel secure in the knowledge that they won't ever be held responsible for their actions - unless witnesses are brave enough to stand up and testify in a court of law.Witness,an organization founded by English musician Peter Gabriel,helps victims find their voice. His idea: arm as many people as possible with cameras to raise the world's awareness of human rights abuses. Without NGOs like Witness and the organization's staff - people who often risk their lives for their work - much of the evidence against war criminals would not come to light. Bukeni Waruzi spent six years collecting filmed material on child soldiers - video that was used in the case against Congolese warlord Thomas Lubanga at the International Criminal Court (ICC).
