So what new constitutional rights violations do we have here? Next they'll be doing door to door warrant checks, with SWAT teams. Here's the rub, these cops go around randomly scanning license plates, and let's say you borrow your brothers car, which he loaned to some guy that killed his girlfriend. Next thing you know, your being pit maneuvered, and tasered. Or, that $100 parking ticket you payed never got entered into the system to get you taken off the hit list, and just as your leaving work after a long day of "customer care", your arrested for a parking ticket. That you payed. But for some reason the cop doesn't believe you and thinks your being resistive, "taser time".  Or how about the "pre-crime" deterrant they are just implimating in New Jersey. This gizmo has a camera on a light pole, with a bull horn, AND a high powered red light that can light up a person a block away, in sync with the camera. High def. camera of course. "This has the potential of stopping crime before it happens", yeah, in 1984. And now police have UAV's (drones) just in case some terrorists happen to be planting IED's in your neighborhood. Right now, these drones are armed with "non-lethal" means of assaulting American's with bean bags, and tasers, but once these cops figure out it's impossible to hit a moving target with a bean bag while trying to avoid jet liners, and trees, they'll move up to fully automatic, heatseeking, laser guilded, infra-red,  self-arming, night vision, weaponry of military grade. Just think soon we'll have no police, to speak of, just a couple of guy's with joy sticks, doing law enforcement from hundreds of miles away, with drones that have automatic license plate readers.
