The people who wanted the unredacted memo released wanted to show that Barr was acting on his own and had already made a decision. The judge agreed and ordered the memo released. The memo showed that indeed Barr was following the recommendations of those in the DOJ and not acting on his own. The reasoning of the memo was sound. There was no crime to cover up. There was no evidence hidden, there was no falsification of evidence. There was no obstruction.
You can be sure the judge is disappointed.
