Its still to be detremined what crime as been commited,so no proof he is wrong,I doubt you'll accept that.
Never say never, but for the moment I disagree.
The two investigations were opened / reopened based on an assessment of facts, and opportunities to further explore what happened to this little girl and who (if anyone), was criminally responsible for an - as yet - undetermined potential criime.
So far, ok.
Both jurisdictions stated that the parents weren't suspects. Although that could always change, so far it hasn't.
I find it absurd to imagine that both police forces had ignored any of a list of criminally liable possibilities involving the parents prior to stating that they weren't suspects.
Since when would two independent police investigations in two countries be (re)launched to concentrate on proving or disproving a theory of one particular officer (and his entourage) who coordinated the investigation for its first 5 months?
There are always going to be supporters of the "thwarted hero" amongst conspiracy theorists whatever the
subject. Although conspiracies do exist, IMO there are far more theorists than actual ones. Conveniently, it feeds into the current populist zeitgeist narrative of David v Goliath, or whatever represents a particular archetype.
