I don't think the European cops are all that much better people, even if not as murderous.
Living in Paris a couple of years ago I used to regularly see cops street racing to a local restaurant for lunch with their sirens on. Their driving style was basically exactly what you'd expect street-racer kids in Eastern Europe.
That kind of casual abuse of power is very telling.
I live in northern Europe. It's not uncommon that our cops carry submachine guns and their cars are massive. Your generic middle eastern or african paramilitary would be rather jealous of their equipment.
