The letter makes the final report sound more positive toward Trump than I expected. I'll be interested to see the final report, especially the obstruction-of-justice part which seems less conclusive and which the AG's letter only briefly summarizes.
On the negative side, Mueller did snare a pretty routine, average member of the Washington District of Criminals, Manafort.
And he entrapped very unfairly, Flynn.
Those events stand as warnings to any who would think of going against the swamp.
