The dichotomy of Rifts

[Bill]

That's also a valid interpretation. There isn't a canon answer though.

Great easy for me to munch up the burbs though.

The cs isn't dumb.
Letting a few powerhouse D-bees live in the burbs, serves several purposes.
Information.
Enforcer.
Shows that as long as you know your place subhuman trash doesn't always need to die.
Follow the rules, fight for us when needed, and never expect to be treated as anything more than a stray dog, you just might live.

The CS isn't dumb, but I doubt that it is a conscious decision of theirs to allow any particular "powerhouse D-bees" live in the burbs. I would expect that it is merely a result of insufficient manpower devoted to patrolling the burbs. I would expect them to temporarily supplement that manpower if they became aware of numerous or powerful supernaturals in the burbs.

I don't know if that jives with the numbers from CWC and other sources. Could be just as plausible a reason for supernaturals to be there as evasion or complicity though.
