Book Review: Failed Evidence: Why Law Enforcement Resists Science

As of this writing, the Innocence Project lists 311 exonerations. If that number is extrapolated to cases in which DNA was unavailable, the number of wrongful convictions becomes far greater. Yet — except in rare instances — law enforcement officials have alarmingly failed to identify this as a systemic problem. A curious position, given that when the wrong person is convicted the real criminal roams free, possibly committing more crimes. Why do these officials remain so resistant to the growing body of scientific evidence that exposes defective practices and can guide much-needed reforms?
