When it finally came time to acknowledge the inevitable and seek to dismiss the charges, the U.S. attorney couldn’t resist taking one last stab at vindication, saying of Dr. Wecht, “He wasn’t acquitted of anything. It was a hung jury. However, in our society, everyone is innocent until proven guilty.”

Indeed. And as Ms. Buchanan spectacularly failed to prove Dr. Wecht’s guilt, that last insinuation of guilt was inappropriate. It is time for Ms. Buchanan to take responsibility for her failure and resign before President Barack Obama asks for her resignation, which he could not now be blamed for doing.
