The Mueller probe avoided any approach that would "result in a judgment the President committed crimes."
Today we see that is *not* what Mueller Report says
It states DOJ does not allow that - not for Mueller, not for AG- and thus the Report details evidence.
No charges possible means no charges possible, not by Mueller or by Barr.
So Barr's letter was incorrect in its depiction of Mueller. (Barr can reach his own separate views.)
