WHAT?
That's the scariest thing I've heard in ages. It's been my experience that even the most immersion style players of D&D go on complete psycho rampages when they try an espionage (well, supposedly espionage) game. I don't understand it at all. I try playing a character with style and panache, I get "co-workers" who carry around flame throwers and custom-made 8 gauge shot guns that fire slugs instead of shot. I try running a game where the mission is to make a contact, and return with a report. The PCs want to requistion a van with concealed machine guns, an EMP grenade (the info they're looking for is on a computer) and a remote control car to load full of plastic explosives.
And Spycraft is coming out with GTA inspired rules supplements? I need to forget about a James Bond style game for at least 20 years, don't I?
