One place where law and morality are supposed to agree is that there should be no crime without a criminal mind, what is called “mens rea” in criminal law. But there have been a proliferation of crimes that do not require knowledge or intent, contributing to over-prosecution and overincarceration. Conservative and libertarian lawmakers have claimed the moral high ground over progressives in advocating that people who do not intend and do not know they are breaking a law be excused for their criminal conduct. Is this correct, or is it just a cover to make white-collar crimes harder to prosecute? Today we look at the battle over mens rea reform in the criminal justice system, the moral theory underlying the idea that being culpable for wrongdoing requires an objectionable state of mind, and why it is that human beings care so much more about mindset than they do about conduct.
