Some people say that America has a mass incarceration problem: Too many people are in prison. That’s only possible if one of two things is true: (1) Large numbers of incarcerated persons were wrongly convicted; (2) We are incarcerating people for frivolous reasons.
Regarding (1), human epistemic limitations will always result in some people being wrongly convicted of a crime they did not commit. However, given the safeguards of our judicial system (innocent until proven guilty, appeals process, etc.), this is bound to be a very small percentage of the incarcerated population.
