OK, that's not exactly my question, but it's close enough.
I recently did a quick lookup on the birth family of the wife of my grandmother's first cousin (just wanting to fill in some names and dates, you know), and found myself reconstructing some unusual biographies -- notably for her brother, who was by profession a spy. (He worked for American military intelligence, and he probably retired before the CIA was established.)
I looked here for a category for "Spies" as a profession and found none. The one relevant category seems to be Spies and Traitors. It seems to have been set up for a sub-project of the Blacksheep Project. The mission of the Spies and Traitors project is "to highlight the profiles of those who were either suspected or accused and convicted as a Spy or Traitor." That's all well and good for people like Mata Hari, Nathan Hale, Kim Philby, and Benedict Arnold, but does everyone who did this as their profession truly belong in the Black Sheep category? (I don't think so.) Can we work out a scheme that distinguishes this profession from the glamorous Black Sheep category?
