The documentary maker's latest series has got people talking.

Louis Theroux is back at it again and this time it’s in a three-part series called Dark States. The second documentary from the series, Trafficking Sex, aired last night and included the moment he sat down with a former pimp. Shederick Smith is currently serving a 42-year sentence in prison in Amarillo for trafficking a 15-year-old girl, known only as LD in the court documents. During his conversation with Theroux, Smith seemed completely unapologetic for his work as a pimp, claiming that many of the girls he “worked with” enjoyed the work.

“Some women are just hoes. You know? They’re prostitutes, and that’s all they're gonna be.”

In official documents, LD said there were times she didn’t want to work with Smith and that he treated her badly. Smith defended himself by saying the girl in question was only with him for seven days which wasn’t enough time to be “too horrible”. The interview was chilling to watch but was praised by viewers who again commended Theroux for his incredible skill.

Louis Theroux is simply a master of journalism. Although he focuses on others, it’s him I find fascinating.#LouisTheroux #DarkStates

Louis having a polite and probing conversation with this pimp over a jail phone might be the most British thing I’ve ever seen #LouisTheroux

Louis Theroux shows us time & time again that the way to get the most vulnerable to talk is to listen, be subtle, & listen again #DarkStates
