I stumbled across this article about Aili Malm, a GIS specialist (I think) who uses social network analysis to find the most probably locations of organized crime.
"I look at where organized crime groups are located and I study how these groups are linked to one another," she explained. "I can chart their cell phone use or e-mail communication or with whom they co-offend. Based on these connections, I try to isolate the important players. Then I take the social and make it spatial. I look at individuals important to the criminal network and map where they live and where they commit their crimes."
It's just like that show Numb3rs on CBS. Albeit, math and statistics is a bit glorified on the show, but hey, at least it's loosely based on reality.
