This is a very good point. There seems to be no coverage of whether the actual perpetrator was ever caught. We employ and compensate the police, admins and fund the judicial system, at least partly in order to serve as a deterrent to criminals. If our system has a high percentage of false positives or punishes innocent people then that reduces the efficacy of the system as a deterrent. I'm reminded of this exchange between a journalist and a British justice minister where the minister seems incapable of understanding that punishing people who turned out to be innocent isn't an effective system. https://www.youtube.com/watch?v=_DrsVhzbLzU https://www.youtube.com/watch?v=_DrsVhzbLzU
