"That's exactly what makes it important to have a legible legal procedure which says, we think this person has a ninety-two percent chance of being guilty, which is over the eighty-five percent threshold that all the cities use for non-souldeath murder. So he goes to the Last Resort, which is the place that has to accept you when nowhere else would accept you any more."
"What's the alternative? Pretend to be certain? Pretend that a court in Golarion that claims to be totally certain of its findings, won't actually be wrong at least one time in seven if not more? When your courts output probability judgments, you can check against the cases where the criminal files a confidential report with the Confidential Criminal Court Calibration Commission saying what actually happened, or the cases where decisive evidence turns up later.

"Is it the fault of the number, seventy percent, that you're ending up unsure?

Not reasoning in numbers isn't going to help you not be sure."
