Josh Nowlan (R) leaves Arapahoe County District Court in Centennial, Colorado April 27, 2015. Nowlan was shot in the left calf and right arm during a mass shooting in Aurora on July 20, 2012. Colorado's long-awaited cinema massacre trial began on Monday with opening statements in which jurors were asked to decide whether gunman James Holmes was insane when he killed a dozen moviegoers in 2012, or a calculating mass murderer who deserves execution. Holmes pleaded not guilty by reason of insanity to multiple charges of murder and attempted murder for opening fire inside a midnight screening of a "Batman" movie at a Denver-area multiplex in July 2012. Twelve people were killed and another 70 were wounded in the shooting. REUTERS/Evan Semon
