"Making a Murderer" directors Laura Ricciardi and Moria Demos spent 10 years of their lives following the story of Steven Avery and, at the Netflix Television Critics Association event yesterday, the two were on the defense as they were grilled about leaving some key evidence out of the 10-part series, according to the Guardian.

"This is a documentary," said Ricciardi. "We're documentary filmmakers, we're not prosecutors, we're not defense attorneys. We did not set out to convict or exonerate anyone. We set out to examine the criminal justice system and how it's functioning today."

"It would have been impossible for us to include every piece of evidence that was presented during Avery's court trial," she continued, according to the Hollywood Reporter. "Of course we left out evidence, there would have been no other way to do it. We're not putting on a trial, but a film. The question is, of what was omitted, was it really significant? The answer is no."

The media has been swept up in the question of Avery's innocence and whether or not he was treated fairly by local authorities.

"The media are demonizing this man in order to prove his guilt," said Ricciardi.

Avery recently filed an appeal of his conviction and claimed that authorities used an unacceptable warrant to search his home and that one of the jurors on his case was out to get him, according to ABC News.
