Sure it sounds insane and I'm not sure if I believe it but I don't think it's outside the realm of possibility that organizations like that exist. Read about the Marc Dutroux case, really creepy stuff. https://en.wikipedia.org/wiki/Marc_Dutroux

This suspicion that Dutroux had been, or was being, protected was raised when the public became aware of Dutroux's claims that he was part of a sex ring that included high-ranking members of the police force and government.[16] This suspicion, along with general anger over the outcome, culminated with the popular judge in charge of investigating the claims, Jean-Marc Connerotte (fr), being dismissed on the grounds of having participated in a fund-raising dinner for the girls' parents.[16] The investigation itself was wrapped up on the grounds of conflict of interest. On the witness stand, Jean-Marc Connerotte (fr), the original judge of the case, broke down in tears when he described "the bullet-proof vehicles and armed guards needed to protect him against the shadowy figures determined to stop the full truth coming out.[16] Never before in Belgium has an investigating judge at the service of the king been subjected to such pressure. We were told by police that [murder] contracts had been taken out against the magistrates." Connerotte testified that the investigation was seriously hampered by protection of suspects by people in the government.
