Why didn't they do this sooner?

Opening a new front in the war on terror, the DoD is now highlighting perceived errors in MSM reporting on an open web site. They take on, for example, a Newsweek article:

INCORRECT NEWSWEEK CLAIM: “In the countryside over the past year Taliban guerrillas have filled a power vacuum that had been created by the relatively light NATO and U.S. military footprint of some 40,000 soldiers, and by the weakness of Afghan President Hamid Karzai’s administration.”

RESPONSE:

* Qari Mohammed Yousaf Ahmadi, generally viewed as the Taliban’s current chief spokesman, stated publicly on Sept. 15, “The Taliban forces have conducted a tactical retreat.” It is difficult to fill a power vacuum if your forces are retreating. ....

It seems unlikely that this, or any effort, would cause the MSM improve its accuracy. But it is, at least, helpful for the public to have access to more information.
