From Abu M:
Some folks in the public affairs shop at the Pentagon were predictably upset that they were not in the loop regarding the report's release, but this is Pentagon spokesperson Geoff Morrell speaking today on behalf of his civilian boss, the Secretary of Defense:

[The report] is exactly the type of candid, critical self-assessment that the secretary believes is a sign of a strong and healthy organization. This kind of honest appraisal enriches what has been a very real and hearty and vigorous debate that, frankly, has been taking place within this building, within this department and within this government for years now.

Well that's my earlier puzzlement answered why in the public domain.
