Criminal Justice
Examining Ethics and Responsibility in Law Enforcement
Criminal Justice (On Campus Program)
A Comprehensive Look at Crime and Justice
The Criminal Justice major at Simpson goes far beyond policing. You’ll examine crime, criminal behavior, and justice through a wide lens — analyzing root causes and evaluating how society responds. From understanding why crime happens to studying how institutions and communities address it, you’ll develop the ability to think critically and apply justice theory to real-life challenges.
Courses explore a range of pressing topics including mental illness, substance abuse, immigration, punishment and reentry, and the reimagining of justice in modern society. You’ll also engage deeply with issues of criminalization, systemic disparities, and how justice can — and should — evolve.
