My bet is, Garland has realized he, the DoJ, and FBI have screwed the pooch on how they went about this raid. Now Garland is scrambling to try and put a fig leaf of credibility on it. If that weren't the case, the warrant wouldn't have been sealed in the first place. The operation wouldn't have been a surprise raid like it was.
If Garland, the DoJ, and FBI can't convince the public-at-large that the raid was on the up and up, they just handed Trump and his wing of the Republican party a huge issue that will cause them to turn out in larger numbers in November. For the Leftists here, that's the reality of this, like it or not.
