If you can’t get 13/20 in this Line of Duty trivia quiz, you’re a bent copper

Or will we, yet again, mistake corruption for incompetence?

With Buckells revealed as the fourth man, Steve and Kate imprisoned in the world’s most awkward friendship, and Hastings raging against the dying of the flame, Line of Duty could well have reached its natural conclusion.

But how well have you been paying attention? Do you know your trapdoor from your pear tree? Your AFO from your UCO, from your OCG, from your RTA, and so on?

We’ve devised a Line of Duty trivia quiz so hard it’ll make you feel like Buckells. If you can’t get 13 or higher, I’m afraid you must be a bent copper.
