Our research examined the competing costs and benefits of several laws, doctrines, and guiding philosophies in the American criminal justice system that are justice-frustrating, meaning that they allow serious crimes to go unpunished and often unrecognized, whether inadvertently or by design. While much of academic literature has understandably focused on combatting causes of injustice, it is also necessary for a morally credible system of law to be able to control and prevent crime whenever possible.  Wherever we recognized a justice-frustrating issue, we constructed a detailed reform proposal aimed at fixing the root cause of the issue.
