This is what I have believed all along too.
In his radio broadcast last February Peter Boyles called JR the Albert Speer of the crime. If any know the history of the Holocaust, Albert Speer was Hitlers right hand man who helped keep the wheels of the persecution of the Jews going, even though the war was lost. Afterwards, when war criminals were captured, Speer made every effort to show he didnt even know about the final efforts to continue and hide the extermination of the Jews. (It was a big fat lie). But Speer came out of the situation pretty good and was spared the death penalty. He even wrote a memoir.
When I have read the thoughts about JR really being somewhat of an innocent bystander to PRs or BRs murderous rage, or possibly only somehow just making an instant decision that late morning (?) of the 26th to help PR, imo and respectfully, Ive some niggling issues with that idea. And I also begin to have a sense about Boyles comparison.
Starting with the 911 call that morning, while I havent heard the voices at the end, others have. There is a significant change of vocal intonation after PR thinks she has hung up the phone. Assuredly, JR and PR had been married long enough that he knew why her tone changed.
There are also the lies to LE about when he was in the basement (at least 3 times it turns out) and his false allegations about what he moved down there.
Later there was the request to PP to retrieve his golf clubs from the basement. Middle of winter and ya need the golf clubs.
JR was also heard muttering, as though speaking to JB, Im so sorry, Im so sorry at his friends home after the homicide. When asked what he was sorry about, he said he was sorry he did not protect JB. Innocent apology or does he know exactly what happened to JB? IIRC, JR was the first one in his family to be lawyered up, and his lawyers were hot on the tail of FW. Why?
Finally, we have the mystery of the garotte and the black fibers from the inside of JBs new size 12 bloomies.
I dunno, (the extent of his involvement) but just cant give JR a free pass. All moo.
