Gotta run, but it looks like the police "swept" Salt Lake City, Denver, and Portland. I'm not sure how much that matters with horizontal scaling. When you cut a rhizomic plant in two (like the highly invasive Japanese bamboo) you get two plants. And if you rip the plant up and scatter the bits, each bit grows into a new plant.
I think that's what's going to happen. 2012 is going to be a very interesting year.
NOTE On the other hand, the ME and IA Occupations seem to be going just fine. It's a big, big continent.
