The militant Jihadist group ISIS released video of the beheading of journalist James Foley in retaliation, it says, for the U.S. air strikes in Iraq. Foley went missing on Thanksgiving day, 2012, in Syria. In the video Foley is kneeling against a desert landscape, wearing something resembling an orange prison jump suit. ISIS is threatening to kill another journalist they are holding if air strikes do not stop. Has the role journalists play in war zones changed? Missouri School of Journalism professors Mike McKean, Earnest Perry, and Amy Simons discuss.
