You can agree to whatever method of classification you like.It's how scientists worldwide classify deaths.
Otherwise (if they did it some different way) a person could get shot in the belly, die a week later from sepsis from the wound, and the murderer gets off.
It wasn't the gunshot that killed them; it was the infection that did it.
You tell me, what killed this person. The bullet trauma or the subsequent infection they would not have gotten but for being shot in the ******* belly?
But that isn’t science.
And I didn’t realise science and scientists (rather than legal principles and judges/juries) determined the causation element of a criminal offence.
You’re all over the place.
