According to RDM:
I think that some of the Colonies have developed very different cultures and attitudes from one another and that it's rich ground for us. We alluded to some differences here and there, but mostly we talked about the "Federal" (for lack of a better word) governmental structures. We do know that there was a sizable opposition to the Colonial government. Leoben claimed to be an arms dealer supplying freedom fighters or terrorists, depending on your point of view, and Tom Zarek was the jailed leader of a sometimes violent opposition, so it stands to reason that there are a wide variety of views, some of which come into violent conflict with one another. It's also worth bearing in mind that one of the uses for which the Cylons were originally used by the Colonies was as soldiers in their wars against one another
- CIA : Colonial Intelligence Bureau. CIA = Colonial equivalent to the Central Intelligence Agency. Whereas the Colonial Investigation Bureau handles law enforcement, the CIA is more concerned with intelligence, including extremist groups such as those on Sagittaron.
- CIB : The Colonial Investigation Bureau is the Colonial equivalent to the FBI. Investigates federal crimes and crimes crossing colonial jurisdiction boundaries.
