rashomon,
What you posted is ambiguous on two counts. So I'll restate my opnion.
Patsy prior to turning up for the Atlanta interview was already aware JonBenet had been redressed in size-12's e.g. either via the media or/and her legal team, take your pick?
This is privileged information, were you present that night?
You really must read the interview, you will be rewarded. Patsy is anything but evasive, although she does have recurring amnesia at points. She tells us that she purchased two packs of Bloomingdales size-12's on her trip to New York, and that she placed one of those packs into JonBenet's bathroom panty drawer!
So via the size-12's she links herself to the crime-scene!
There are no size-12's in JonBenet's bathroom panty drawer, and since Patsy arrives at the interview forearmed with the knowledge that someone had redressed JonBenet in size-12's, why should she concoct a story that may be falsified?
All she needs to say is I left the size-12's in the wine-cellar/basement. I guess the killer must have redressed JonBenet in them?
The facts are simple.
1. Patsy states she purchased size-12's from Bloomingdales.
2. JonBenet was discovered wearing a pair of size-12's
3. No size-12's were found in the Ramsey house.
Patsy lied to the interviewer about the size-12's, in such a maner that she was immediately contradicted. Why does she need to do that if it was her who redressed Jonbenet and disposed or hid the remaining pairs? Surely she could dream up some other explanation, even one involving JonBenet's killer e.g. he took the underwear with him as a trophy.
The only reason Patsy lied in the manner she did was because she is covering for someone else, and did not know the size-12's were missing or that just prior to the wine-cellar staging, someone had redressed JonBenet in those size-12's. If she knew she would have had cover story ready one that may not be correct but certainly one that could not be disputed never mind contradicted?
This why she starts forgetting stuff during the interview, she has already stated she purchased two packs of size-12 underwear, one for JonBenet at her request, and another as a gift for her niece Jenny. So in theory there should be 13 pairs of size-12's in the house, Patsy is queried on this indirectly when asked that there should be an unopened pack of size-12's lying somewhere in the house, Patsy agrees!
Patsy is attempting to keep her version of events consistent, and in doing so overcomes her amnesia.
So I reckon someone had already redressed JonBenet prior to her arriving in the wine-cellar. This is consistent with JonBenet being redressed in longjohns and wrapped in a blanket, simply not required unless you want to hide something e.g. the size-12's.
That is at the time of the wine-cellar staging Patsy was not aware that JonBenet was wearing size-12's!
If I understand you correctly, you're saying PR came to the interview with the knowledge that JBR had size 12s on. Have I misunderstood this point?
Assuming I have understood correctly, why wouldn't she simply say she put the two packs of 12s in the basement and she doesn't know what happened to them?
