The immediately obvious answer would be “over the prosecuted if you’re only ‘testing’ the courtroom itself, over all the people if you’re ‘testing’ the whole system”, but I’m not sure what the ‘ideal’ thing for a courtroom to do in terms of P(C|Prosecution, G) and P(C|P,I) if the police is ‘non-ideal’ so that P(P|G) is not close to or greater than P(P|I) to start with. Or even whether this question makes sense… I’ll have to think more clearly about this when I’m not this tired.
Are we restricting to cases that are prosecuted or doing this over all people?
