OK two FOA disagree. I actually think it should be used. In fact it IMHO is one of the key pieces of evidence which disproves the Massei/Mignini theory. We know a lot about couples that engage in rape/torture/murder.
Male -- Sadist, sexually dominant, psychopathic
Female -- Extreme masochist. Identifies with victim is highly aroused by demonstration of power.
If we want to argue this was a deliberate rape torture murder with Amanda taking the lead; then she is expressing a very highly masochistic sexuality. I want her profiled. I want to see evidence from Amanda's lovers of extreme masochism. For example Karla Homolka, freaked out many of the men she had relationships with by how rough she liked it.
Similarly Raffaele. Is he sexually functional without domination? Is he sexually aroused by non sexual violence?
Or maybe it was Rudy. Same thing. Was Rudy sending off the vibe and Amanda was switching over.
The prosecution wants to have Amanda playing the female role in a rape/torture/murder but also be motivated by jealousy. Now there are female killers who explode in jealous rages, and they have an entirely different psychological makeup. This is the sort of nonsense that litters the prosecution's case; where they don't stick to one theory.
So we disagree here. I'd like to see profiling given the nature of the prosecution's claims. Profiling, I think would knock a huge hole in their silly theories.
