> A researcher who focuses on a range of surveillance technologies, Maass said he has a particular problem with license plate readers because every driver needs a tag to get on the road. It’s a requirement, he said, “that was not designed for this purpose.” “There’s not a lot you can do to protect yourself from them other than just stop driving,” Maass said. “They’re set up in this way that, in order for you to get to work and to travel freely, you have to submit to your data being monetized by a private company and then sold to law enforcement.”

There's a few videos on the youtubes where perfectly law-abiding citizens were pulled out of their vehicles at gunpoint due to false positives from systems like this.
