Mexican officials have announced they intend to deploy 10,000 police officers for Pope Francis' visit to Mexico in February. The Pope's trip is expected to draw over 2 million people, with an estimated 300,000 attending Mass in Mexico City. What presents a significant challenge for security forces is the Pope's destinations are in areas known for extremely violent activities because of drug cartels. The Pope always travels with one of the most respected security organizations in the world, and given his personable nature and fondness for interacting with crowds, this visit will present an enormous challenge for security forces.
