I have spelled out for you that in all 50 States there is no penalty for knowing that answer as a non-sworn civilian, or even writing a book about it under the first amendment and in a free market economy. You don't have to get immunity for ANYTHING if you left that part out of your story, and otherwise solved the case. You said you could do so "EASILY". This all leads to the fork in the road
He gets it. Even this imbecile understands he does not need immunity.
He wants to use the immunity card for several reasons. One is that it keeps him from having to actually tell what we now all know, he doesn't know.
The other reason and to this sociopath more importantly is that by continuing to play the "I demand immunity" drama, he gets to come off as the dangerous man that he wishes he was instead of the lying loser that he is.
He hints at the one thing on which he will not get immunity - murder. He wants people to believe he has killed. I mean he has posted it hundreds of times. But in connection to these cases he wants to be seen as a mysterious man with "answers" but that will bring him danger.
Get it? He is playing everyone. He never has to put up or shut up as long people buy into this farce.
