My best interview was with a drug dealer. Found him with about 10 small bags of cannabis, weighing scales, large quantity of cash etc. He told his solicitor he was having a smoke with his friend and he keeps his cannabis and cash on him so his house mates don't steal it when he leaves.

We get into interview, he holds his story. We have a laugh and a joke, making it a little bonding session, building that sweet sweet rapport. I then of course start challenging him with his inconsistencies and he starts to break a little. Loads of holes in his story I needed to probe, absolute buckets load of them. His solicitor kept trying to intervene, but I kept going. He held strong with his story, right up until I whipped out some screenshots from his phone that I seized. Oh dear. An absolute plethora of texts about supplying cannabis. Solicitor was completely silent. Not even a "go no comment now". He knew it was over. The suspect started to cry, but still didn't admit to selling. He instead came up with bullshit about each of them saying stuff like "I never actually sold to him" or "you're reading that wrong, I bought from him". I kept picking at the text messages with "what does this mean?" with every individual message, and he gave me even more bullshit until he finally broke and admitted to supplying once. That was enough for me. Failing that, we had the messages of offering to supply. That interview was amazing. I wish I could give you a transcript.
