Not a major point, but...
The problems are with basic maintenance at the facility. Unless U.S. Army generals are supposed to be spraying fungicide on the walls and crawling under beds to set rattraps, the slovenly conditions at Walter Reed are not their fault.Mold growth is not caused by failure to spray fungicide or to clean thoroughly. It's caused by moisture, usually from roof leaks or plumbing problems. The problem is apparently one of infrastructure deterioration.
One of the ironies that I've seen while in the Naval Service is that I've never been in a Navy building that didn't have at least one leak in the roof.
It amazes me that we can operate submarines.
