We've certainly learned a lot this year about the surveillance state. Thanks to the cache of intelligence documents leaked by Edward Snowden, as well as the hoards of legal records we liberated through our Freedom of Information Act lawsuits, we've had immense amounts of new information to consume and process. But how many of the details do you remember? It's time for a pop quiz.

And Dec. 21 just happens to be the 100th anniversary of the crossword puzzle.

We've written about the word games top US officials play when defending the NSA's massive electronic surveillance system, so it felt especially appropriate to round-up the highlights in one big crossword puzzle. You can click the puzzle above for a larger image to print, or just download this PDF. 

UPDATE: TheDod made a slick interactive version of the puzzle that you can access here.

(A tip: Whenever we're asking for a name, we mean only the surname.)
