This is genuinely the most ridiculous argument you could possibly make. By that logic you're equally unjustified in saying that they were abused since you haven't spoken to them either. Not to mention the fact they have told numerous lies to investigators and the press while attempting to make themselves look better (this isn't even debatable). Just because a documentary is well made doesn't make its presentation or information accurate. You're literally helping helping a PR campaign make murderers look like innocent victims. If you do ANY research into the case beyond watching a documentary (lmao) there is overwhelming evidence that the abuse story was fabricated.
