In his book, Twenty Million Angry Men: The Case for Including Convicted Felons in Our Jury System, James Binnall discusses whether or not there is sound empirical evidence that proves that ex-convicts should be barred from participating in jury duty. Currently, most states in the United States permanently forbid those with a felony conviction from serving as a juror while some states allow convicted felons to serve only after their entire sentence (including parole and probation) is completed; Maine is the only state that has no restrictions whatsoever.
