Today many people make telephone calls casually, with not much thought given to cost. For that you can thank cell phones and calling plans that include all the minutes you might want to use. But for people who are in prison, picking up the phone and connecting with their lawyers, family, and loved ones on the outside can be an expensive proposition. Dr. Artika Tyner is Director of Diversity at the University of St. Thomas School of Law, and an authority on something called prison phone justice. KFAI's Rico Morales talked with Dr. Tyner and her colleauge Terri Schmitz about helping families stay in touch when someone is incarcerated.
