We're on season 3, it really goes fast when the seasons are only 5 or 6 episodes.
Throughout the seasons, I can't help but point out how many times a situation would have been different if the cops were armed. One of the Icelandic detective shows I watched on Netflix had a scene where they were at a warehouse, heard gunshots, and had to call their supervisor and explain the situation and why they should be given the combination their vehicles lock box where the firearms are stored. It's just so unnatural to my American mind.
