Smart Decarceration is a forward-thinking, practical volume that provides innovative concepts and concrete strategies for ushering in an era of decarceration -- a proactive and effective undoing of the era of mass incarceration. The text grapples with tough questions and takes up the challenge of transforming America's approach to criminal justice in the 21st century. This timely work consists of chapters written from multiple perspectives and disciplines including advocates, researchers, academics, practitioners, and persons with incarceration histories who are now leaders in the movement. The primary purpose of this book is to inform both academic and public understanding -- to place the challenge of smart decarceration at the center of the current national discourse, taking into account the realities of the current sociopolitical context -- and to propose beginning action steps. Smart Decarceration offers a way forward in building a field for decarceration through provocative but reasoned challenges to existing approaches to criminal justice reforms, lively focus on potential solutions, and action steps for reform.
