I have to agree with this, and I want to believe that was the needle Comey was threading. I am concerned, however, that his tone in the last hearing (eg. "mildly nauseous", Abedin email forwarding mistakes, immigrant investigation mistakes, etc.) was so flippant that he was almost asking to be fired. By design or by accident, he's departing more independent now than ever.
I'm glad I wasn't the only one who thought his tone was inappropriate. Leave that for the tabloids to sell, don't bring it into the political institution.
