Does this have any bearing on whether Madeleine's case is close to being solved? The Germans don't seem to have convinced you.
There has been a progression over the past fifteen years even if your preference is for ground hog day.
Who knows ~ if the PJ had carried out due process earlier in 2007 to the logical conclusion fresh eyes eventually reached there might have been time.
There was no evidence against the McCanns. There never had been any. Had that been accepted and other options followed we could have been at the stage we are at now of investigating Brueckner either to eliminate him or bring him to trial.
It isn't as if he didn't have a presence in the area and one iota of the time spent checking McCann phone data might have turned up a lot more which was actually pertinent to the case.
The fact the phone he was using actually had been recorded in the files but hadn't been checked out will probably emerge as one of the big fails of investigators.
