Thanks to Wikileaks publishing the Dutroux Dossier in 2008, we know hundreds of snuff films were recovered from the notorious pedo-rapist Marc Dutroux.
Just because the police keep those films as sealed evidence that are never published does NOT mean snuff films are an Urban Legend. I can see why the police always keep snuff films secret. Imagine what would happen if snuff films were uploaded all over the Internet? There would be mobs of angry villagers armed with torches and pitchforks descending on jails and prisons to lynch pedos. It would make harassment from QANONs look like school yard bullying.
