That's another problem. Every human on the planet is an agent, since there are no rules for non-agent characters.

*sigh*
They are called NPC classes.
So Geoff, do usualy run or play d20? If you play, you just need the PHB.
If one RUNS a d20 game, the PHB, DMG, and MM are considered manditory. D20 games like SpycraftFading Suns and Deadlands sort of make assumptions that the GM will know what to keep and what to toss out. In the DMG, one could still use NPC classes despite the shift in the genre and pardigm. To paraphase the DMG and my Star Wars book, "These NPC classes are not really playable for heroes. They represent the rest of the people in the world around the PCs: hardworking professionals who don't go on adventures or battle dangerous foes."
The NPC classes in the DMG would be those such as the Expert, Aristocrat, Warrior, and (ahem) the Commoner. Perhaps it would help to rename the NPC classes to modern nomeclature for you. So try Academic, Politian/Movie Star, Law Enforcement and Average Joe.
As an aside even the MM has some uses since it has animals (guard dogs, sharks and spiders) Other MM entries can be genegineered beasts (Dire Animals), or for a supernatural campaign.
Or if one has the STAR WARS book, one could use it's versions of the NPC classes, such as the Diplomant, Expert and Thug. The Star Wars book also has some NPC multiclass/prestige templates that would make sense for a modern campaign (I'll just rename some to make them fit the 21st Century.)
Those classes are Adminstrator, Generica Assassin, Generic Bounty Hunter, Generic Con Artist, Generic Crimelord, Generic Elite Trooper, Generic Fighter Pilot, Generic Gambler, Generic Medic, Generic Mercenary, Generic Military Officer, Generic Outlaw, Generic Pirate, Generic Smuggler, Generic Spy, Generic Tech, Generic Theif, Generic Thug, Generic Trader, Bounty Hunter(PrC), Crimelord(PrC), Elite Trooper (PrC), Figther Jet Pilot (Starfighter Ace), and the Officer (PrC).
So there are some decent rules for non-agent characters for those humans who aren't Player Characters in the basic three books needed for d20 before you even use the Spycraft rules. One just has to use a little tweaking for the setting and you are good. If one happened to snag the STAR WARS book, then one has plenty of sample characters.
Perhaps if you don't plan to run a d20 game, then a Spycraft purchase wouldn't be in the best interest right now. If you would like to run d20. Get the other two books and read throughly first.
