Arizona’s legal woes could delay the trial of alleged Tucson gunman Jared Loughner up to six months. Federal officials have declared a judicial emergency in Arizona because of a lack of judges to handle a flood of immigration-related cases and the death of the state’s chief federal judge, John Roll, in the Tucscon attack. Doctors for wounded Rep. Gabrielle Giffords, meanwhile, have upgraded her condition to good from serious. Giffords has been moved from an intensive care unit to a rehabilitation hospital in Houston. The news comes as more details have emerged on Loughner’s actions before the attack. According to the Washington Post, Loughner conducted extensive online research in the weeks before the attack on lethal injection, solitary confinement and political assassinations.
