Did Robert Mueller's press conference Wednesday make anybody happy?
Especially when he set a new, impossibly high standard, for Trump.
The “I couldn’t exonerate him” point is discomfiting for another reason, which is: Since when do prosecutors exonerate people? That isn’t a prosecutor’s job. Maybe in the aftermath of a wrongful conviction, with irrefutable physical evidence, prosecutors will say something exculpatory. But even in most of these cases, they usually drop charges on grounds of insufficient evidence, not positive proof of innocence.
