The "Polite" began because they were like Pigs with the Community, foreign occupying Soldiers. They are African Bodysnatchers of a Family unit, explaining some of their behaviour. Local Police are excitable about Crucifixion & things that produced Apocalypse in Biblical Times.
The "Roman Soldiers" we're not as portrayed in Movies, rough looking & vulgar in fact. They burst into Public areas talking up violence with support nearby & forced their way to the Bar as they move Traffic with sirens only because it's on their route.
