This is an outstanding Washington Post article/opinion blog post by Erik Wemple on the Diane Sawyer interview with Hillary Clinton.
I learned long ago that the conjuction "but" wipes away all that was said just prior to it; it's a word that allows the user to look like they are doing something, all the while - in reality - avoiding it.

"The accountability-heavy moment came when Sawyer’s slow and steady line of questioning on Benghazi security prompted Clinton to utter this self-contradictory and sure-to-be-repeated statement: “I take responsibility, but I was not making security decisions.”
For the record, possible-presidential-candidates-in-abeyance should never attach conjunctions to their declarations of responsibility-taking."
This moment in time with Diane Sawyer may be looked back on as a water-shed moment - an opportunity to look into the contradictory thinking/communicating patterns of Mrs. Clinton.
Her opponents should take note.
No "buts" about it.
