Hmm...
Well, in 40k and similar places, how that works is that a single hand had extreme difficulty grasping a lot of stuff, especially with barbarians (demons) at the gate *see Fall of Rome*
As such, an "underground" is established that would act that way...actually, Kadia came from that.
So, in an imperium, we have
A) Imperium vs. Common folk
B) Templar vs. Demons
C) Police vs. Underground

I think if you mixed B) with C) you'd be good...
Actually, I can reference another source that is similar to this - Hex Coda. Essentially, one large Corporation owns everything, but the Hex Coders try to make freeware and the like illegally and compete with these guys.
