&quot;Proof&quot; by evidence is an inherently statistical process. E.g. cops find a DNA match between a suspect and skin cells found under a murder victim&#x27;s fingernails under circumstances where it is clear she tried to fight off her attacker. Does that &quot;prove&quot; guilt? No, it proves that under similar circumstances, guilty is highly likely. The problem is not that the justice system is statistical. That&#x27;s unavoidable. The problem is the unfortunate confluence of the low standard of proof (&quot;more likely than not&quot; versus &quot;beyond a reasonable doubt&quot;) combined with the high ratio of illegal versus legal reasons for carrying large amounts of cash (<i>i.e.</i> a high prior odds ratio).
