NightSide - Professor Paul Crawford Explains The Crusades

BOSTON (CBS) - In a speech given at the National Prayer Breakfast, President Obama talked about religions being corrupted by evil extremists. In his remarks, the President referenced the Crusades and slavery as examples of Christianity being perverted, before then going on to condemn ISIS as a "death cult." Do you think President Obama undermines his own strong words against ISIS by bringing up events from hundreds of years ago? Does comparing the dark times of Christianity to the current evil we are facing send the wrong message? Dr. Paul Crawford from California University of Pennsylvania explains the crusades.
