I think you mean the Police Chief must be delusional. He's the one who stated the purpose of the cameras which have license plate readers...
"At the May 19 regular council meeting, Fulshear Police Chief Kenny Seymour said his goal is to install 25 license plate readers to help his department solve burglaries and break-ins; only about 15%-20% of those cases are ever solved."
They are in use in my small town as well, and I have personally witnessed an officer confront a person who came up as suspicious (not a county resident) based soley upon their license plate at our local dump.
Your officer probably had a reader in their car, many police cars are equipped with them.
