The county name on a plate also shows whether a vehicle is registered locally or not, which may be relevant in identifying suspicious behavior.”

and let police pick on those out of county types who were dumb enough to cross the county line.

This is reasonable. If the police are looking for someone from Sample County, it helps them ID the perp. Why not? They ought to be able to read the whole license plate.

Texas doesn't have county names on plates. The state said that I the frames hide the state mane, the vehicle can be stopped. It also said that the toll road cameras cannot send the "Pay by mail" charges to drivers.

Well, there is am impression of Texas in the center of every plate. Of course, that shape could be easily mistaken fo another state. < /sarc>
