This morning I was looking at some charts at the hospital where I work in order to decide whether some patients had infections or not. You might think that would be pretty straighforward, but a lot of medicine is not black and white, but varying shades of grey. In the case of infections, there is no one test that means "infection" vs "not infection". The doctor needs to put oa lot of things together to decide if the evidence is leaning more toward infection. That made me think of discussions I 've been reading lately about the evidence in the JBR case and I thought I might shed some light on/remind people about ways to look at evidence. There are certain things that have only one explanation; those things are evidence of all by themselves. For example, a skull fracture is evidence of an injury to the head. Some things about the skull fracture might be evidence suggestive of a particular set of circumstances or a particular item causing the injury. But, the skull fracture by itself only tells you that there was a head injury. Evidence that is suggestive of something points in a particular direction, but does not mean that is the correct direction. The more evidence suggestive of something that points in the same direction, the more likely it is that it's pointing correctly. But, it may be that the people who are looking at the evidence are only looking in one direction, or only have experience in that direction - or have a bias toward going in that direction. One joke in medicine is that if you go to a surgeon, he/she will suggest surgery as the solution, no matter what the problem is. It can be that way in anything. The final thing to remember is that the coroner doing an autopsy already knows that the person is dead and He/She is looking for things that could possibly have caused the death. That doesn't mean that the cause(s) listed is written in stone as the reason this person died or that anyone with a similar injury would always die, only that it was one of the things that was so out of the normal that it was a likely cause.
