So, what is the "official" reason that Stevens was in Benghazi (terror central) on 9/11 with no security, no advance team, no escape plan. Are they hiding a CIA op? I think so. Why? To what end? The op is blown, or maybe they don't know that.
The story changes every time an unexpected consequence arises. The goal seems to be avoiding consequence rather than establishing a cover.
The meanderings reveal a lack of discipline in an arena that requires complete dedication and to an extent, the willingness to give no answer even when it may project a political image that is unpleasant. The evolution of the story is not consistent with revealed facts but seems to be the approach of a the average school age child who has not yet recognized that the world does not conform to imagined scenarios.
If this is a cover for an op, that is being handled very poorly.
