Bradley Manning has confessed in open court to providing vast archives of military and diplomatic files to the antisecrecy group WikiLeaks, saying he wanted the information to become public to make the world a better place". Appearing before a military judge for more than an hour on [Feb. 28], Private Manning read a statement recounting how he joined the military, became an intelligence analyst in Iraq, decided that certain documents should become known to the American public to prompt a wider debate about the Iraq War, and ultimately uploaded them to WikiLeaks. Before reading the statement, he pleaded guilty to 10 criminal counts in connection with the leak, which included videos of airstrikes in Iraq and Afghanistan in which civilians were killed, logs of military incident reports, assessment files of detainees held at Guantanamo Bay, Cuba, and 250,000 diplomatic cables. The guilty pleas exposed him to up to 20 years in prison. But the case against the slightly built, bespectacled 25-year-old - who has become a folk hero among antiwar and whistleblower advocacy groups - is not over. In a riveting personal history, Private Manning portrayed himself as thinking carefully about the categories of information he was divulging, excluding the sort that would harm the United States. He said he was initially concerned about diplomatic cables in particular, but after doing research learned that the most sensitive ones were not placed into the database to which he had access, and he concluded that those might prove "embarrassing" but would not cause harm.
