The whole video is a fraud. O'Keefe edited out the actual questions that were asked and then inserted his own voiceovers that had nothing to do with the questions:
http://www.newscorpse.com/ncWP/?p=26595"The controversy enters with O’Keefe’s narration that inserts the words “ISIS” and “terrorist” in place of what was actually said. Then O’Keefe slanders Scaffido by concluding that he is pro-ISIS and that Cornell welcomes terrorists to its campus...The problem that is apparent is that Scaffido’s answers above were not in response to the actual questions asked."
Disgusting, O'Keefe is.
