Other people read this forum, too. Some of them work for the military and maybe even at Walter Reed. By posting the problem in public, it opens the possibility that someone, somewhere will do something to fix it.
It's sort of like when reporters sneak fake weapons through airport security to show the TSA's failings. Would you rather that they not expose the problem?
I want the problem fixed, of course....but I also don't want to futher endanger our wounded troops....a few calls to Cap Hill might get the job done.
