Welcome songdog and attyjay. As a relatively new poster, who mostly is a Columbine researcher, with just a passing interest in the JBR case, I think that the more you learn and explore this website and the plethora of postings, the more you'll see (as I did), that the IDI theories just do NOT hold any water.
The only issue here really is figuring out which RDI, TBPFH. I tend to lean towards BR whacking her on the head and either PR and/or JR administering the lethal garroting, and the PAINFULLY obvious staging scene and ridiculous RN (authored by PR).
Foreign Faction,
Although you can produce evidence and scenarios for each of the remaining residents in the Ramsey household, they do not explain away the anomalies and counter-examples, over the years you tend to see people exhibiting
confirmation bias when promoting their favorite RDI theory. Consider the books written each with a well thought out theory suggesting it was either PDI, JDI or recently BDI, they cannot all be correct.
Consider this we assume JonBenet was killed around midnight of the 25th, so if it was one of the parents they had all night to cleanup, e.g. run all JonBenet's forensically contaminated clothing through the washing machine, why was this not done, why elect to dump a bloodstained pink nightgown into the wine-cellar and destroy a staged crime-scene?
Why did John or Patsy not cleanup the breakfast bar, or even insert that JonBenet snacked pineapple prior to going to bed, into their version of events?
We know that Patsy can invent accounts since she has one regarding the size-12's, yet there were no size-12's in JonBenet's underwear drawer, so why did Patsy not place the size-12's into JonBenet's underwear drawer, so to match her version of events, answer: because she was ignorant about the size-12's.
Then there are the hair ties on JonBenet's head. When did they arrive, after she was put to bed sleeping by Patsy, or after she was killed?
This all suggests to me, since I reckon if the case was either PDI, JDI or both then the crime-scene would be more consistent with the R's version of events, that the parents arrived late on the crime-scene and enacted a quick cleanup and staged JonBenet's death.
BDI is the only theory that explains away nearly all the anomalies and inconsistencies, even down to Hunters behavior, and the GJ result.
