Your post might have assumed some validity were you capable of arguing exactly what did not replicate the circumstances which ~ in my opinion ~ led to the assumption that a formula which had resulted in conviction and therefore kudos??? for the investigators, was worth trying again in similar circumstances.
The parallels even included the opportunity to make a bob or two from best sellers written by cops on both cases. I rather suspect you have no argument (what's new?) for the simple reason none exists ... the hypothesis being very reasonable.
My query was around your assertion that there was a "determination to replicate......" implying, by the use of the word determination, that it was deliberate on the part of the PJ.
I don't need to put up a cogent argument contrary to yours, it is down to you to justify your stated position and field questions preferably without your customary sneering, goading and boasting.
