A complete guide to all the abbreviations that have cropped up in Line Of Duty so far…
For instance, who the hell is H? Is DS Steve Arnott’s addiction really going to result in him being killed off? Is DI Kate Fleming a) falling for DCI Jo Davidson, and b) truly on her way to becoming a bent copper? Can AC-12 leader Ted Hasting ever hope to shake off his past disgraces? Who killed the CHIS? And…
Well, what even is a CHIS? Or an AFO, for that matter?
You see, that’s one of the many, many, many things we love about Line Of Duty: it never dumbs things down for its audience, with complex police terminology being no exception.
But, while we do appreciate the show’s writers assuming the best of us, it’s still pretty tricky trying to keep up with all those acronyms and abbreviations.
