This document summarizes three major justice theories: Adam Smith's theory of moral sentiments, Emile Durkheim's structural functionalism theory, and Howard Becker's labeling theory. It discusses their key ideas including Smith's concept of sympathy, Durkheim's ideas of social solidarity and anomie, and Becker's focus on how labels can become self-fulfilling prophecies. The document analyzes how these theories relate to problems with mandatory sentencing laws and their disproportionate impact on women, noting issues like lack of sympathy, social breakdown, and harmful labeling. It concludes by suggesting removing labels could help address these problems.
