Pope Francis' terrifying security breakdown during his Brazil trip

Thousands of Catholics swarmed Pope Francis on his first overseas trip as pontiff aimed at marking the biennial World Youth Day in Rio de Janeiro. Security was tight — but not enough to withstand the crush, and at one point, the swell of bodies was so deep that his car was actually forced to a halt. American security experts slammed the Brazilian security procedures.
