Police Detective
A Police Detective investigates crimes, gathers evidence, interviews witnesses and suspects, and works to solve criminal cases. Detectives specialize in areas such as homicide, fraud, narcotics, or cybercrime. They collaborate with prosecutors, forensic experts, and other law enforcement agencies to build strong cases. The role demands sharp analytical thinking, attention to detail, and strong communication skills. Detectives often work irregular hours and must navigate complex legal and ethical standards while pursuing justice.

Criminology Course
You will explore the major theoretical frameworks that criminologists use to explain criminal behavior, from classical deterrence and rational choice to sociological, biological, and critical perspectives. You will learn how crime is measured, what official statistics reveal and conceal, and how researchers design studies to uncover the full picture of offending and victimization. The course covers specific crime types including violent crime, cybercrime, organized crime, and terrorism, applying theory directly to each category. You will also examine how policing, courts, and corrections operate, and evaluate which interventions actually reduce reoffending. By the end, you will be equipped to read, critique, and apply criminological research with confidence.
