This note follows a very precise format and its structure is straightforward and direct. There's an attention grabbing introduction, and then an idea is stated, and then each idea is followed up with elaboration, and so on. There's a spot though, where writing about the delivery and pick-up that seems to lose focus-as if the writer is distracted, and then the next part gets really hardcore and focuses on JB' being murdered. So IMO, these parts may have been written right before and right after the final act of murder. In other words, the writer was distracted, left the note writing, murdered JB, and then went back to note writing. After Kolar's 's book came out, there was quite a bit of discussion on the time lapse between the bash and final strangulation, so IMO, writing the note, may be what the killer was doing during this lapse. Anyway, back to the format and structure. The author didn't identify himself until the very end, with the SBTC signature. IMO, this points to the name being made up during the writing, otherwise, he would have identified himself when referencing the small foreign faction. So, what does this mean? This is what I think. Because the note's structure follows a very precise format, it's my opinion that the last paragraph follows the same format...where each idea is followed by elaboration. IMO, the last paragraph is a personal plea to JR to unite with the author, and the follow up is elaboration. So, the, 'it's up to you now John! Victory!', is the author saying that united, they will be victorious, and the 'S.B.T.C', would be something along the lines of, 'Separate, Broken, Together, Complete', or Single, Bared, Together, Covered', etc. Anyway, it's moo based on the flow and structure of the note, that the author probably wouldn't have back referenced to the foreign faction or thrown in a random religious reference. all moo.
