The whole principle behind the notion of "information sharing" is the common sense idea that two heads are better than one. All concerned parties get together, share what they know on a given subject, bat the facts around to come up with analysis and ideas for what action to take. "Brainstorming." It works in business, it works in the law, it works in daily life, and it works in the Intel Community.
For example, you bring analysts from different intel agencies together under the direction of John Brennan, they brainstorm ideas, and then Peter Strzok writes up the Intel Community Assessment the way John Brennan wanted it from the beginning. Then they foist the ICA on 1) an unsuspecting public, and 2) a cynical and witting political establishment. What a concept! What could go wrong? Well, Donald Trump, Devin Nunes, Bill Barr, John Durham, an aroused American public.
Eric Felten has a wonderful article on intel sharing today at Real Clear Investigations, and you need to read it all:
How an FBI Team in Rome Gave Steele Highly Guarded Secrets. Wait a minute, you say? The FBI shared "highly guarded secrets" with a private citizen of a Foreign Power? That can't be right--that can't be approved! Information sharing is all fine and good, but there have to be some restrictions when it comes to "highly guarded secrets," right?
Indeed there are, but they only apply to chumps like you and me. Certainly not to High Bureau Officials. And so Felten chronicles--it's all there, buried deep inside Michael Horowitz's FISA Dossier--how the FBI shared "highly guarded secrets" with Christopher Steele, knowing full well that he was working for the Clinton campaign.
One's first reaction is bound to be: Should I laugh or cry? Is the US lead Counterintelligence agency being exposed as the Keystone Kops of the Intel Community? But rest easy. There was a very good reason for the FBI to share its "highly guarded secrets" with Steele. To understand why, you need to understand the context of the meeting at which so much of the sharing went on.
As you'll see when you read Felten, the meeting in question took place in Rome. It took place on October 3, 2016. The FBI had, by that time, received most of Steele's "information", but they needed more. In light of that, consider the timing for the Rome meeting. The date of October 3, 2016, means two things: The meeting took place
after the Crossfire Hurricane investigation was opened, but
before the Carter Page FISA was applied for. So, what kind of information was provided to Steele?
This kind of information:
