Number of people required to keep quiet about it: 1000+
Sorry, the people in the government are about as smart and savvy as everyone else, with some exceptions both ways (keep in mind that many people in the military are only there because the judge said it's that or you're going to jail). And back in the days when there were only a few people per operation reporting to only a few people with little oversight, yeah, maybe you could keep some things secret. But not anymore - too many people are involved. Things like torture will eventually come out, unless it's done locally and not in a real organized, authorized fashion over in places where things like that are very commonplace anyway, i.e. Iraq and Afghanistan.
