Could you provide some contemporary examples in Scandinavian or Western Europe of where organized crime has had a blind eye turned to it as a result of using mafia-sponsored "muscle"?
Scandinavia is the poster child for ethics, and from what I know I would say rightly so, but it's not representative of Western Europe as a whole.
Your inclusion of Sarkozy surprises me. Googling for Sarkozy and mafia is bringing me a bunch of antisemitic sites and a site called info-resistance — do you have any reliable sources?
So there's a long history of shady ties at the very top of the French institution, pretty often in the form of what was deemed as a "necessary evil", but corruption nonetheless. That's pretty much summarizes the spirit of the French Fifth Republic, anyway: "we go to do what we got to do, and the public wouldn't understand".
