Ft. Hood: A female MP is being credited with heroism in the latest Ft. Hood shooting. She confronted and fired at gunman Ivan Lopez before he killed himself. Specialist Lopez used his own .45 caliber pistol, which is prohibited to have on the base, but soldiers are not searched when they enter to report for duty. Lopez spent several months in Iraq but was never in combat. He had sought help for depression and anxiety and investigators are looking further into his psychological troubles.

Nation: The Senate Intelligence Committee voted to release part of its report on the “brutal” treatment and interrogation of terror suspects by the CIA in the post 9/11 “War on Terror.” Part of the report says the CIA misled the Bush Administration about the severity of its methods.

It chronicles a stain on our history that must never be allowed to happen again. This is not what Americans do.”

The moon Enceladus, which is only 300 miles wide, was first discovered to have giant ice crystals on its south pole in 2005.
