Exorcising Mexico's Demons

Roman Catholic priests in Mexico are turning to exorcism to fight the gruesome drug related violence that is engulfing the country. The drug war has claimed more than a hundred thousand people in the last decade and clergy say that this can only be the work of "those possessed by the devil". Many cartel gang members are also followers of the cult of St Death which priests say leads towards Satanism. As a result, Mexico now has more exorcists than any other country in the world. Vladimir Hernandez reports on their battle to conquer evil.
