MICHAEL WALSH: ANOTHER LAUGHABLE BENGHAZI LIE:

More than two months after an Islamist attack on the American consulate in Benghazi that left four Americans dead, including US Ambassador to Libya Chris Stevens, we still don’t know what really happened that night — and, thanks to a secretive White House and an incurious Washington press corps, we probably never will. Not officially, that is.

But there’s no real mystery about it. From the evidence that’s emerged in dribs and drabs since the Sept. 11 calamity, it’s clear that Ansar al-Sharia, a Libyan al Qaeda-affiliated group coordinating with its allies elsewhere in the Muslim world, used the cover of riots in Cairo to launch a preplanned assault on our lightly guarded Benghazi consulate and a CIA safe house that may have been doubling as a secret prison. . . .

What’s also heart-rendingly clear is that our diplomats and security personnel understood the danger they were in, repeatedly requested more resources — and were left to die, as US military and intelligence assets monitored their deaths in real time, lacking the orders to protect them.

Benghazi was a first-class military and moral disgrace, and one that the Democrats paid absolutely no price for in the recent election.

But the questions won’t go away. Who gave the order to stand down as the consulate was under fire? Who came up with the cockamamie story — so eagerly peddled by UN Ambassador Susan Rice and other administration spokespersons right after the event — that the sacking and looting were in response to an obscure video that lampooned the origins of Islam and had been posted on You Tube for months?

And why did President Obama cling to such a risible explanation, and then (with a timely assist from Candy Crowley in the second presidential debate) turn on a dime and claim he knew the assault was terrorism all along?

It will come out in the end, I suspect. Meanwhile, Mr. Nakoula is still in prison, because imprisoning a filmmaker was convenient for the President at the time.

UPDATE: Meanwhile the NYT is rowing back the video story.
