I understand, selection bias. I mean I don't know how Mark chooses his interviewees (he never says and he's never shown on the street) but many of them are extremely unsympathetic (certain pimps, for example), a couple are simultaneously likeable but clearly evil, and some are super boring, so I don't think there's any kind of intentional bias.
