Suppose LE have 10 facts that only the killer would know. Why wouldn't they release 8 and keep back 2? That should be enough.
Unless they're hoping someone trips up during an interrogation and says a fact only known to the killer and LE.
"I can assure you it's not what they're experiencing today" quote makes me think the killer posed the girls as if they're...in hell somehow? That would indeed be bizarre
I'll just say this. Do not underestimate the importance of religion, specifically evangelical Christian theology and its concept of salvation, in the lives of both these particular investigators and the Delphi community. You have to look at what they say through a lens of understanding because they are actively using an evangelical model of faith in God/the afterlife to cope with the murders of Libby and Abby.
We have heard from Abby's mom that one of her first thoughts on learning of Abby's death was regret that she didn't have Abby baptized immediately upon her profession of faith a few months prior (source: podcast Scene of the Crime). We have heard from the FBI special agent in charge Jay Abbott that the investigators started each day of work with prayer. Tobe Leazenby has explained that he is a man of faith and that this particular belief leads him to think the crime will be solved because evil cannot triumph over good in his theological worldview. And most prominently, Carter has spoken openly in the press conferences about his ideas of coping with tragedy through faith. Unfortunately, his attempt to analogize the situation in Delphi with the fictional portrayal of a Christian take on forgiveness and redemption, was clumsy and was then seized upon and twisted by listeners into other meanings IMO.
When Carter spoke with anger about "how you left them...is NOT what they are experiencing today" he is not referencing anything specific about the crime scene other than the killing of two young children is always senseless and that these two particular girls - in his opinion - are in heaven now. His concept of what heaven is like would have been shared by most everyone in attendance at that press conference IMO and would have been understood to mean that the girls were now "saved," "with Jesus," and "no longer in pain or fear."
All MOO
