Yes, cops are always very cool here in Denmark. Drunk (I need to watch my language)s can insult them very badly, and they wouldnt care.In fact, drawing out a weapon(Did they pull out their guns in this case where you got caught speeding?)
is rare. Shooting is reason to get fired unless you were about to die.
And yes. You can get arrested for insulting. But in most cases, cops dont do this.
A formal investigation is conducted each time a cop draw and gun and fires the gun - even if it is only a warning shot...
