Washington Post downplays WMD story - surprised?

Early Warning by William M. Arkin:

"The threshold for labeling something WMD in this world is low, if it exists at all. Many of the 'chemical munitions' found in Iraq were even 'unfilled' shells. That is, they had never been filled with chemical agent, according to the summary. But, as Rumsfeld says, 'they are weapons of mass destruction.'

The implication here is that we should drop to our knees and pray at the WMD altar, fearful and desperate to let the professionals deal with the 'men's work' of national security."

I wonder what the story would be if one of those "degraded gases" were released by an "insurgent" on the Metro or a subway in NY?
