She didn't say she got flashes of Patrick because she was told she had amnesia. She said the police harassed, yelled, and forcefully insisted she was there and the person in the text message was who she met at the cottage and they had proof she was there, and they wouldn't let her deny being there as an option, and the cherry on top is manipulating her by telling her she has amnesia, transforming the vague police reconstruction forced into her mind as the only story they were accepting into "memories." A coercive interrogation resulting in a false statement isn't an exciting new revelation and has a significant historical basis. And your last point is wrong, by admitting to being at the scene of a staged break-in that she later informed the police was genuine, she was very clearly implicating herself in the crime. The real killer probably would have remembered they spent hours staging a break-in and discovery and not tell the police they invited the killer in through the front door.
No, you just throw out one straw man after the other. Raff lied after caving into strong threats from the harassing police, thinking he was choosing the easy way out by cutting his losses with this girl he just met that the police insisted was involved in a murder of a girl he barely knew. It was a poor strategy on his part but interrogation tapes of the cops saying "protect her and we'll beat you to bloody pulp and put you in prison for 30 years" probably wouldn't play out favorably for the cops. And again, it makes little sense to immediately give up his accomplice to the police if she can implicate him and take them right to his knife.
