How about something completely out of left field to explain the bs interviews of the R's...
What if LE concocted the R's story for them to present in order to get either or both PF and KK talking. Both are only communicating with LE through their layers (PF for sure).
The story would need to contain enough truths to convince both PF and KK that the other was talking to LE (first) to get the best deal. The story would need to be told, and relayed to PF first, in bits and pieces over days to be able to go back at him multiple times to say "look, she's talking. when it all comes Sunday, your time to talk is up. it's all on you now."
At the same time, go to KK and sell her the same story with a different slant. "we've given you (KK) a plausible (bogus) out, tying it all on PF. PF is buying it and has started talking. he's giving us details (that LE already knows). he's putting all of the planning on you. by Sunday, he's getting the deal if you don't talk."
If all of the info in the 3 part story was presented together at once, I think everyone involved would have the same reaction as we did - this is a fantasy fairy tale. Having layers tell the story makes sense in that they would know the legal conditions (with LE agreement) under which they could do this without being disbarred.
