Wolfie directly contradicted himself on the sniper tape. When Lynne refers to it as "terrorist propaganda" at 4:15 on the tape, Wolf gets defensive and says "it was not terrorist propaganda". That's at about 4:15 on the tape. Then at about 4:55, after getting slapped around a bit by Lynne, he says that CNN "clearly identified the tape as propaganda".
The poor guy was clearly outmatched.
