It's probably too much to hope for, but the possibility has been raised that backup tapes for Lois Lerner's damaged, then destroyed, hard drive may still be available. It would be like finding Judge Crater.

The House Oversight Committee continues to seek answers about the selective scrutiny by the IRS for conservative fund-raising groups seeking tax-exempt status. Ms. Lerner headed the office in question, and has taken the Fifth Amendment when questioned about what happened. She has since resigned from the IRS.

The tidbit on the backup tapes for Ms. Lerner's computer originally came in testimony from IRS Deputy Associate Chief Counsel Thomas Kane. He reported it's possible that not all the backup tapes for Ms. Lerner's hard drive had been recycled.

Unfortunately, new IRS Director John Koskinen was unable to shed any more light on the matter during recent questioning by the Oversight Committee. He did promise, however, to look into the matter. So the search for truth goes on.

We can only hope that the IRS is not as assiduous about recycling as it has been about who gets a tax break in the political fundraising department.

Emails released by the House Oversight Committee last week provided further evidence of that mindset, as Ms. Lerner described Republicans as "crazies" and worse.

But back to Judge Joseph F. Crater, who disappeared in 1930 after getting into a cab on a New York City street and being driven away. For years, he was the paradigm of the unsolved mystery, but who remembers him now?

A collective lapse of national attention may be what the IRS hopes for, too, as the Lerner affair continues to drag out month after foggy month.
