I guess the problem is there's no such a thing as a person having "a 10% chance of being innocent" Either he is or he is not. He might have certain probability of being declared guilty (which is entirely different), but I don't think there's a way to estimate that.
BTW 99% is a very low accuracy. If we accepted that for aircraft, 13 would crash weekly.
