Dr. Ernie Drucker will be speaking about his research on prisons, with the exploration of mass incarceration as a public health problem that is especially crippling poor and minority urban communities. Dr. Drucker will discuss his latest two books, "A Plague of Prisons," and "Decarcerating America," and offer suggestions for how the system can be reformed. After the talk, there will be an open discussion with the audience, a book signing, and refreshments.
