Try arguing with a Norwegian police officer. Even calmly. Odds of ending up in jail overnight are pretty high, though you might find one with a sense of humour now.
Norway is one of those countries where shouting insults at a police officer can be illegal where shouting those same insults at a random strangers would not be - there explicitly is one law for public officials and one for the rest.
The idea of public officials being above the rest is deeply embedded in the Norwegian system, and only started fading with the growth of the labour movement, and steady inclusion of the labour movement into the establishment starting with the first lasting Ap (labour party) government in 1935 onwards. Even then, Ap took up the baton (..), and wielded it against the groups to their own left, with extensive illegal political surveillance for decades.
The reason Norway is now as civilized as it is, is simple:
Norway eventually got filthy rich thanks to the oil. The average salary in Norway is about 70% above the average salary in the UK, for example, and the salary curve is far flatter.
We've had social democratic ministers from a party that used argue for revolution and was an early member of Komintern that are millionaires. A long range of our past "threats" to the establishment are now wealthy and firmly embedded in the establishment. The class struggle in Norway is largely "on hold", and the police is being wielded against immigrants instead.
