In Sweden it's fairly safe to tell someone, anyone really, to go fuck themselves. I don't care how much in the right I would have been had this been in Catalunya and the officer in question had been with the Guardia Civil - no way I would have said so then. I'd have been in BIG trouble!
So Gus, my advice to you is this - come to Sweden, but you'd have to do better than being on the phone while driving to get pulled over, and say what you have to say here. Don't worry about language barriers either. Most Swedes speak decent English. He'll understand. 🙂
