Why didn't Amanda give the police hints that it was Rudy? Why would she have left the evidence of Rudy if she didn't want him caught?
Rudy was taboo for her. She had never mentioned his name before he was caught, even after that she did it very rarely.
However, she did give indirect hints by not flushing the toilet.
"I see that now in an expanding round of racist charges against Amanda it is speculated that she knew she was being recorded and therefore named Shaky in a conversation in order to have the police suspect him."
She did not name Shaky in that conversation, Raffaele was guessing who she was talking about (which is in itself interesting). He came up with the name and person.
In terms of the overall theory of the PGP this is the greatest single weakness. Why set him up and then finger others?
She couldn'r finger Rudy, because he had been really there and his name or person did not emerge at that time. Naming him would have really implicated her deeply.
Naming Lumumba was a panic decision on seeing Raffaele's support evaporate.
