From the Wikipedia page on police corruption:
Case of Marc Dutroux[edit]
In 2004, the high-profile case of Belgian serial killer and child molester Marc Dutroux resulted in outrage in the community amidst allegations of police corruption and incompetence. Dutroux was meant to be under police surveillance the night he kidnapped two of his victims, but the police had programmed the camera to operate only during the day. The police failed to locate two living victims being held captive during a search of Dutroux's home in 1995. A locksmith who was accompanying the police during the search said he heard children's cries, but was dismissed by the police. The police claimed that they did not view seized videotapes of Dutroux constructing his "dungeon" as at the time they had no VCR. Dutroux claimed he was part of a sex ring that involved high-ranking members of Belgian police and government. The widespread anger over the continued failings of the police and Dutroux's sex-ring allegations, as well as residing judge Jean-Marc Connerott's dismissal, led to the "White March" in 1996, demanding reforms to Belgian police and judicial systems. Connerotte testified that the investigation was deliberately hampered by officials. Dutroux also escaped from police custody in 1998 before being apprehended. A parliamentary commission into the Dutroux case in 1998 found that the defendant benefited from police corruption and incompetence. Although police were cleared of direct compliance in Dutroux's crimes, the report cited major gross negligence throughout Belgium's police system, and an overhaul was called for. The case severely damaged the Belgian community's trust in their police and law enforcement systems.[34
So once again I ask: do sceptics think that Operation Grange is corrupt, and has been set up specifically to deflect from the crimes of the McCanns by focusing solely on stranger abduction and have they set out to pervert the course of justice by deliberately ignoring any evidence that pointed back at the parents?
