(AP Photo/William Hennessy) (Newser) – Three year after his arrest, Bradley Manning's trial finally began today, with both sides offering their opening statements and two conflicting narratives of the man emerging. Tasked with proving that Manning actively aided US enemies, prosecutor Capt. Joe Morrow told the courtroom that this was a case of "what happens when arrogance meets access to sensitive information," claiming Manning "systematically harvested hundreds of thousands of documents from classified databases and then dumped that information on to the Internet into the hands of the enemy," the AP reports. Manning's attorney David Coombs argued that the 25-year-old army private was "young, naive, but good-intentioned" and said he only released material he thought would do no harm and help make the world a better place. "He believed this information showed how we value human life," said Coombs, specifically citing a leaked video of a 2007 Apache helicopter attack by US forces which killed civilians. "He was troubled by that. He believed that if the American public saw it, they too would be troubled."
