I’m not so sure about that. In my country (Hungary) actually all big crimes have to go through the prime minister, he’s working together with the national bank and lots of other politicians, bankers and lawyers to steal the EU money that the country gets. Otherwise it’s a peaceful country (that is getting less peaceful as the government steals more of the economy).
Big crimes make the news, small crimes are when people are getting mugged. Both types of crime are significant, but small crimes are vastly more common.
