The Murder of Louis Allen/One Child at a Time/The Library

The Murder of Louis Allen - Steve Kroft's 18-month investigation into a 47-yr.old murder in a Mississippi town sheds light on an unsolved civil rights killing near the top of the FBI's list. One Child at a Time - Wars can literally shatter children's lives and Elissa Montanti is on a mission to make some of them whole again through a network of volunteers. Scott Pelley follows the progress of one of them, a badly maimed Iraqi boy. The Library - No one is allowed to borrow a book from the Vatican Library - except the pope. And no wonder: the archive holds some of the oldest and most precious works of art and treasure known to man. Morley Safer and "60 Minutes" cameras get to see the best of the best.
