Northeastern University Professor Daniel Medwed\u2019s book \u201cBarred\u201d comes out on September 20. The book focuses on the wrongly convicted people who are unable to overcome the criminal legal system and prove their innocence in the eyes of the system.\n\nAs others have noted \u2013 due to systemic problems, it is easy to wrongly convict and very difficult to correct on the back end.\n\nMedwed discusses both ways to improve the system on the frontend and ways that the system can correct wrongful convictions on the back end.
