Let me preface my comment by saying that I'm RDI, the note is fake, and it was written (and probably composed) by PR.
The thing is - it makes no sense for the kidnappers to have returned the body to the house, especially if she was killed because PR called police. Rationally, the Rs could not have expected the body to remain undetected for very long. So once the body was found it was obvious that the body had been there all along, not killed and returned after the police showed up. It would be obvious that she was not killed in response to the Rs not following instructions. How could the kidnappers have brought the body into the house right under the nose of the police?
So, the note may have originally been written to go along with a plan to dump the body somewhere? For some reason, that plan may have been abandoned. But then, why wasn't the note changed?
Once the 911 call was placed there was pretty much only one chance in a million that the body would not be discovered, so there could have been no plan (at least no rational plan) to dispose of the body after police left.
Chrishope,
This is pretty much how I see it too. I personally place little emphasis on the ransom note. Principally because it was a staged crime-scene artifact, it was not genuine forensic evidence, so to read into the ransom note the intent of its author, is I think to engage in the very process for which the author wrote the note, e.g. confusion.
The ransom note was a detour, a way for the Ramsey's to buy time. They possibly decided prior to dialling 911, precisely what they intended to accomplish e.g. phone friends over, mess up the forensics, relocate Burke, if possible fly to Atlanta ASAP, etc.
The R's thought they knew just how things might pan out. I reckon they had inside advice from both the DA's office and BPD so were going to attempt to bend the protocol, e.g. Pamela Paugh's supermarket sweep.
Assuming Patsy wrote the Ransom Note, all that mattered was that it be credible, the R's needed this to acquire the time needed to execute all their desired outcomes.
The R's thought JonBenet would be found rather quickly, they hoped the staged kidnap, would deflect attention from them to someone outside of the house. This is reflected in John's remarks to BPD officers about having scheduled business appointments to attend in Atlanta. So they expected to avoid due process, probably through their prior contacts and misplaced arrogance regarding their status?
A-priori the ransom note cannot be read as a map of events to come, since the R's would have had same expectations as everyone else. That is the discovery of JonBenet, resulting in possible arrest and interview, the most optimistic outcome for the R's might have been bail, with USofA travel restrictions, e.g. passport handover.
One aspect of the R's plans did not materialise, e.g. the discovery of JonBenet. Nearly everything else was attained including whatever JR did out of sight, except the end-game, the flight to Atlanta. So John Ramsey did improvise, he did put on a bravura performance along with Patsy once he
found JonBenet.
Notably they were not arrested, Det Arndt should have arrested them both on the spot, cuffed them and asked them to take a seat while she phoned her superiors.
Was JonBenet intended to be dumped way from the house, possibly. If she had been, even only a block away, I doubt we would be discussing the R's involvement, this was I reckon, after the size-12's and pineapple, their biggest mistake, leaving JonBenet in the house, casts serious doubt on the intruder theory. Since who kidnaps anyone to leave them behind?
