Target Corp has some crazy AP technology. They actually hold seminars and train the FBI. They setup the surveillance for the entire downtown Minneapolis area. They also rushed some tapes to make critical identifications in big cases to their AP division. They do large busts, including international fencing rings and stuff. They are absolutely huge when it comes to assisting the law enforcement community and have won a few awards.

I don't think consumers have anything to worry about. Who really cares what you buy at a Target store? If you are willing to let the cashier know then why not the AP staff? The odds are so ultra low anyways that they actually are paying attention to you.
