Did you read the Sundance interview with Aldenberg that just hit about one hour ago?    I'm not sure if his prior belief that Barr is in coverup mode holds true now.  It may still be true, but the one thing that was made clear, is that now, without a doubt, they know, that we know the truth.  So this means that a coverup, in the normal since of hiding what is true, is not possible.  Barr can still refuse to prosecute, but the truth will still be known.
