According to the report, the catalyst is Director Brennans allleged desire to do away with the divide between analysis and the clandestine (collection?) service in favour of organising into self contained regional groups.
To this amateur, such a change introduces the risk of "groupthink" where collection activities are shaped to suit the ruling analytic paradigm and unwanted, perhaps contrary, intelligence that doesn't fit the desired narrative is simply not collected. I wonder if it also might negatively impact the security of clandestine assets.
I would like to think that critics of this move within CIA are motivated by a desire to produce "Frank and Fearless" high quality intelligence as opposed to just saving their careers.
I hope Col. Lang might like to comment on this situation.
