Not agreed upon a definition of liberty

This was my first Varg Veum experience and I understand they've made quite a few of these things. To the late arrivals like myself, they should have explained the reason of his existence, throughout the film - as if the story wasn't full of inane plotholes already - I kept guessing is he an ex-cop or ex-military or ex-what-the-fuck. But otherwise, almost decent Norwegian attempt to outhamilton Sweden's Hamilton.
