Didn't ring true to me. But I only watched the first episode -- and I just finished watching all "Shetland" episodes and am spoiled. I'll have to give it a second chamce. But, really, a woman threatening an officer with two, count'em, two knives and the other officers just do nothing? Another officer is punched in the face and, later, spit on by the same person, and only the intervention of a bystander resolves the situation. Really?
