 FACT: The Indiana State Police cars that first appear outside of  Bobs Country Junction while the band is inside eating have a front  plate, Indiana automobiles only have one plate; on the rear.  Furthermore the uniforms worn by the Indiana State Police officers  in the movie are incorrect. They have never worn green and never  worn a jacket. Further along in the movie after the brothers are  spotted at the restaurant and during the road block on the bridge  the correct blue Indiana State Police uniform with upside down  triangle patch (probably worn by actual officers who were called in  to be extras) can be seen in the back (this is just after one of the  troopers wearing the green uniform finishes talking to the person  playing the FBI agent.)
