About the Center for Law, Justice and Society
At its core, the Center for Law, Justice and Society is about preparation. It equips students pursuing careers in law enforcement, forensic science, and legal studies with the tools and training they need to lead with skill and integrity.
But its mission goes further. It is also a place for professionals already in the field — police officers, military personnel and public safety officials — to sharpen their expertise and stay current with evolving standards and practices.
By combining academic excellence with real-world application, the Center aims to:
Empower students and public safety professionals throughout the region with high-level tactical training, technical expertise and lifelong learning.
Foster meaningful partnerships between law enforcement and communities.
Lead policy and research initiatives that shape the future of justice.
Engage with communities to deliver relevant educational opportunities.
Provide inclusive, accessible education for all who serve.
