I don't think AB thinks RA is innocent at all.
I think AB got stung and can't let it go. I think AB thought he could successfully hamstring the State, wanted to get the SW thrown out (bye, bye cartridge in a keepsake box) and introduce an elaborate SODDI story which would open the door to certain individual SODDIs in order to create some kind of doubt among jurors. Unsuccessful with the judge, I think he took to Frank's motions and youtubers to inform infect the jury pool with unsupported, fanciful implausibilty.
IMO there is NO WAY the AB used to think it was a sacrificial offering to Odin, was enlightened, then knew it had to be RL and KAK because of RD's incredible wealth of credibility.
Victims moved and brought back.
Airpods plugged in.
Batteries removed.
Altogether unsupported nonsense.
Just like the narrative that secret hearings were held for which RA's counsel was unaware, only to find out that attorney specifically did not represent RA.
AB should consider going back to his fetal position.
Frank is dead.
