FILE -- In this photo from files taken on Feb. 24, 2013 and provided by the Vatican newspaper L'Osservatore Romano, Pope Benedict XVI delivers his blessing during his last Angelus noon prayer, from the window of his studio overlooking an overcrowded St. Peter's Square, at the Vatican. Planning for the moment when the next pope is proclaimed to the world, and for the installation ceremony a few days later, is a big-time guessing game. And that adds up to an ungodly logistical headache for the city of Rome. Nearly everything went smoothly for Benedict’s last public appearances, although some faithful panicked during the retired pope’s penultimate Sunday blessing from his studio window, when thousands of last-minute arrivals tried to squeeze through three narrow openings through a metal fence ringing the edge of the square.
