Individual Perspective

In reply to Marc's comment on Ignorance is Bliss, I will offer my personal perspective on the CIA investigation.
As someone who has had to closely follow "Rules of Engagement" in many executions of my duties to avoid legal repercussions, I can speak with authority on how this will affect the CIA agents performance and motivation.
It is a real moral destroyer when your superiors who sanctioned your "Rules of Engagement" do not support you publicly to worry about the opinion of critics.
In the case of the CIA, the agents will be more fearful of prosecution, than gathering information. The work standard plummets, security is compromised and some will move to the private sector.
The replacements will be a watered down version of a once powerful intelligence agency, dictated to by politicians who prefer a new viewer friendly CIA.
The politicians are already in place.
I'm certain the new training policies will be announced soon.
