Hullo hullo hullo...what have we got here then? Why officer, it's an episode all about the worst coppers of all time. We invited on QI elf, novelist, lateral thinker and ex-policeman with over 30 years service Stevyn Colgan to join us in settling the subject. As you'd expect, there's plenty of disreputable plods and dastardly inside jobs including brothels, speed cameras, three-card tricks, cross-dressing, lollipops and a very enthusiastic revolutionary. Have a listen and we're sure you'll agree it's a fair cop.
