Though personally I subscribe to the Dean Knight "you might not be interested in intensity, but intensity is interested in you" school.

“See, this Dr Avery fellow says the only reason he confessed was because you were framing him. You didn’t wear gloves, so your prints are on the murder weapon you say you found. And you’ve just finished telling me how you snuck into his bedroom, a fact I now have to disclose to the defence.”

“You chaps have a warrant for any of this? No? Well first things first we’re going to have to section 30 in literally everything you just told me.”
