Self confessed mass murderer and right-wing extremist Anders Behring Breivik (C) moves a water jar at the central court in Oslo on April 20, 2012, on the fourth day of his trial. Breivik, who killed 77 people in Norway last July, took the stand again on the third day of his trial, after having already told the court he would carry out his attacks again if he could.
