Knowing that nothing will satisfy Democrat Congressman Hell bent on taking down this President, Attorney General Barr gave them a head start. By color coding the redactions according to the 4 criteria he defined, he keeps them from asking on each one of the redactions what is behind the blackout. That way they can move right along to some other inquest item. Simple for simple minds.
Unable to get President Trump on collusion, they are turning their attention to Barr who will now suffer the slings and arrows that go along with anyone who does not act on their whims. They may have found the worst thing to happen to them since naming strict Constitutionalists to the Supreme Court; a person who actually follows the laws they passed!
