I have not shifted my opinion, I’m simply saying Hersh should protect his sources. However, as a result, the case he is presenting is weak, since he also failed to provide additional evidence. Considering that in the recent years he has also claimed that 911 wasn’t done by Bin Ladin, as well as Obama’s Seal Team 6 operation did not kill Osama, his credibility alone isn’t enough to convince me at this point.
