 Alternatively, the prior probability can be equated to \(1/n\) where \(n\) is the number of total possible suspects or wrongdoers who could have committed the crime or civil wrong under dispute at trial. This, too, is a plausible proposal. Since someone must have committed the wrong, absent any further evidence anyone could have committed it, so \(1/n\) is a reasonable starting point. But this proposal also quickly runs into difficulties. In some cases, whether a wrong was committed by anyone can itself be disputed. Or there might be cases in which an illegal act was certainly committed and the defendant took part in it, but it is not clear what illegal act it was, say murder or manslaughter.
