UPDATE: Karen, who has plenty of experience dealing with the army's bureaucratic errors (not to mention its substantive errors), puts it in perspective on her blog:
This "Dear John Doe" error is not the worst thing the Army has done and sadly if won't be the last "unfortunate mistake" they make. These kinds of errors, however unintentional, are so painful to a family member who lost a loved one. I wish the Army could get it right the first time. We deserve better.
