Consider This: Should Every DA's Office In Mass. Have A 'Conviction Integrity Unit'?

When someone is wrongfully convicted of a crime in the commonwealth, there is no formal system in place to review how it happened, or how to prevent it from happening again.

Now, a group of legal experts and activists affiliated with the Massachusetts Bar Association has created a new guide to help prosecutors correct and learn from errors in the criminal justice system, in what they say is an effort to rebuild trust with the public.

This guide encourages prosecutors to devote resources to so-called "conviction integrity units," which would review claims of miscarriages of justice and other flaws.
