None of which informs me that PF knew that KK was in WP over Thanksgiving.
Assumption only: According to CBS or the R's telling CBS, KK is cooperating with the FBI. That must be why she has a lawyer, and LE/FBI is still investigating and using SW's. If for example only, KK provided details about where to search for evidence in KB's townhome claiming PF murdered her, that information implicates KK as present at the scene, but it is only KK's statement about PF implicating him.
My reasonable doubt meter on the case against PF was at Swiss cheese level in prior threads, but it is on Tilt at this point. I can easily see a scorned woman doing all of this, perjaps with some unknown helper. I hope LE/FBI have not made a deal only to find out they chose the devil. I have already mentally tossed one solicitation charge against PF because I believe the foundation is R's- BFF employee - KK as related in the first R interview what BFF told them in October - I see it as a fabrication by KK. If this goes to trial against PF, KK is already the worst possible sort of witness and any incompetent lawyer will make mincemeat out of her nonsense.
Cui bono?
