PROF. JOSEPH CAMPBELL: Four weeks on: No answer from WaPo about empty links to Jessica Lynch stories.

Why is some of the Post’s content about the Iraq War — and Jessica Lynch — freely available online while the more embarrassing material shows up as empty links?

Is this a matter of digital scrubbing, akin to Vogue magazine’s excising of a flattering profile of the wife of the Syrian dictator, Bashar al-Asad? The Post last month described the Vogue matter as “an almost-unheard-of step for a mainstream media organization.”

Periodically over the past four weeks, I’ve asked the Post’s ombudsman, Patrick Pexton, about the digitally unavailable versions of the newspaper’s reports about Lynch.

Pexton has promised to look into my questions.

But four weeks on, he has yet to offer a substantive reply.

That’s just embarrassing.
