It is ‘redacted’ because the law says so.
If there is Grand Jury testimony in it, it must be redacted, as GJ testimony is secret and must remain so until or if there is an indictment. The law requires it.
Barr would be breaking the law if he released it unredacted. And Dems and the Mediots know this.
But they know their base is too ignorant of common law to know, so they wave the bloody shirt of ‘cover-up’ all across the airwaves and cable outlets to enrage their base with ‘fake news’.
Also, if there are any National Security issues, such as Foreign Intel Agencies involved or foreign assets (read SPIES) names, they must be redacted, for the same reasons, the law requires it.
But the LIV won’t know any of this, they’ll just get their daily dose of SOMA from the MSM and be told to HATE TRUMP, some more...........................
