The WWII memorial is administered by the National Park Service. As are most? all? memorials. Do you know how much security is involved in these memorials these days??? The entire National Mall is one big metal detector. That takes manpower.
I don't give a damn what the Murdoch Washington Examiner has to say. If I felt like spending more than a minute on the story, I don't doubt I could debunk damn near the whole thing.
Speaking of debunking, Avik Roy was a Romney advisor, and his stuff has been debunked here for years. Burn the Ships often referenced it.
If all this information is so legit, why not use credible sources?
