There are quite a lot of strange things about the entire case handling which has lead to the suspicions growing.
The big question is as you rightly ask, if they were involved in coverup or ring, why are they not in jail?
The evidense is NOT conclusive, and the investigation is hampered from a high level.
Now the Portuguese policeman may well be a liar?
But he did get sued by McCanns and he won his case at Supreme Court since his book tells only facts.
He is convinced they done it or know who done it.
A retired police officer in Portugal wins his appeal against a court ruling that he libelled the parents of Madeleine McCann.

the top detective in uk who captured many prolific sex offenders was happy to take the case but when he started getting strange directives on what he can and cant investigate he pulled out. He was not allowed full control of how or what he investigates. which is similar to one of the claims of the Portuguese detective.
Now does that make McCanns guilty?
Not definitely.
But the stench of something odd is reeking with whole thing.
If and its a big if, but if powerful people can obfuscate the law then perhaps it is a cover up of something.
And if the if is possible then it might explain why the investigation is hampered by power.
But with so little trust in the powers that be, its hard to trust anything you read on the matter.
If sally from haghill abandons her kid in the house and nips out to pub popping back every hour. Is she likely to get millions of pounds worth of investigation and become rich and famous should she pop back and find the door open and her kid missing?
