You have to be careful there. If you look deep enough you can find many elements that are compatible with a theory of guilt. It's especially so if you get to make up that theory to fit those found elements. Adding up the individual probabilities of each of the elements and claiming that they constitute proof if they reach some imagined threshold is invalid because it is a form of cherry picking.
I prefer 'probative' to 'compatible'. In fact, until this case, I had never heard of the latter being used in this context. But let's have none of this 'adding up probabilities' nonsense. The next thing will be bloody Bayesian statistics and I'll really start doing my nut. Psuedo-scientific cobblers for people who can't use ordinary words to express degrees of likelihood.
This whole "compatible" is really nonsense. These are simply elements that neither prove or disprove involvement. The reality is that there are many of these so called elements as there would be for countless people.
But they never really delve into the elements which are not compatible and in fact disprove their involvement. Like;
1. the distribution of glass in Filomena's room.
2. the lack of connection to Rudy.
3. the time of death.
Any and all of these should be considered enough reason to acquit both Amanda and Raffaele.
This is more like it. Look at the totality of the evidence and see what it tells you.
I'm wheeling out the case of David Gillroy once more because it is perfectly illustrative of what a circumstantial case looks like. He was convicted of murdering his former lover despite her body never being found. It's a Scottish case with these circumstantial elements:
1 he was a married man having a secret affair with the victim, Suzanne Pilley but she had broken things off shortly before and begun another relationship (motive - jealousy)
2 she arrived at work on the day she disappeared (CCTV) but never reached her desk (sudden and out of character disappearance suggesting violent end)
3 until that day, he had been sending her hundreds of text messages but then suddenly stopped (knowledge of her death)
4 that day or the next he bought a large quantity of air freshener (to erase evidence of disposal of the body)
5 he made a trip into the Scottish Highlands to a particular destination but the journey took a couple of hours longer than it should (disposal and concealment of body)
6 when questioned by police it was noticed that he had scratched on his hands and face which he had tried to mask with make up (involvement in violence, concealment)
7 (presumably as he did not testify and called no evidence, I think) no alibi
Look at each point individually, forgetting about the rest. Each can be innocently explained. This is normal. Cumulatively, however, they all point the same way and paint a clear picture. He attacked her in the basement of her office building, put her in his car, drove into the highlands and buried her. None of these facts could be directly proved. There are no contrary indicators (as there could be for each point and as Tesla lists above).
Forget about 'adding up probabilities'. That is a needless abstraction. When I catch a ball, I don't work out the maths: the precise trajectory, velocity, the mechanical movement of arms and fingers etc. I can catch the ball without all that crap. Likewise, there is no need to calculate the likelihood of a man innocently buying a large quantity of air freshener on a particular day, even if such a fanciful computation were possible (which it isn't) and add that to the probability that he might also innocently choose to stop texting someone. All pie in the sky. Go to a British court and see how it's done. No lawyer I know would bother with such nonsense.
Gilroy is appealing his conviction btw.
