It might be offensive to some people, but it is not illegal for a central Missouri grandmother to have a license plate on her car that reads ARYAN-1. The United States Supreme Court has upheld a lower court ruling thatthe state’s denial of the plate to Mary E. Lewis is a violation of her free speech rights. She lives near Hermann. She’s been fighting with the state about her license plate for 15 years. Her lawyer says the state has no business deciding what political opinions are acceptable for license plates.
