I mean by tracking criminals cell phones locations, watching how they walk. Checking the network effect ie if a person contacts a previous criminal in the same gang network. Matching photos form surveillance cameras and public social media pictures. Matching walking pose you can pretty much track down criminals. The power is when you combine the different databases and build a profile of the person. It is very similar to how advertisement companies like Google build up profiles of customers(gmail,search behavior,dns name resolution tracking,cookie tracking) only in a different field. It is probably even more powerful when you combine physical behavior with online behavior-
