Cop shows are all about flailing around for a few minutes, followed by a hacker/database identifying the subject and dispatch of the SWAT team. If the computers are down, the good guy beats up the suspect. If the show is on CBS, they do some sort of amazing thing using their MS Surface while driving a Chevy-something. (Bad guys like Fords and Chryslers)

Talk to a real cop. Whiz bang technology is the exception, not the rule. Successful detectives usually use their connections with the community to put two and two together.
