Target has cameras that feed to off site storage. Most business cameras feed to an off site storage. They can triangulate cell phones to a few yard range. If you were looting and had your phone on you they know.

Arrest will trickle in for the next few weeks. Lawyers are lining up to sue the looters. If 1000 people looted a store and burned a store, and if for some reason only 1 person was caught, that person can be sued to recover the entirety of the damages. I hope these people will enjoy 10% of their paychecks for the rest of their lives being taken for a open and close legal judgment.
