I think the profiles of every single person in L.A. or other areas are already there for the police to use. Either with or without the network, the police can investigate someone's profile and, even with that option, they won't bother someone's profile unless they have something suspicious. If having their profiles in the system considered as a privacy breach, I think we all have our privacy breached since we were born, because our birthday, name, and such information were being kept track of since.
