Programme Content

Introduction to Criminology

The course commences by examining the components of crime and seeks to define criminology by exploring some of its basic theories including Classicism and Positivism.

Media, the Law and Crime Statistics

Here students will examine and discuss the communication of crime in our multi-media world and the impact different methods of reporting can have on our attitudes towards crime.Statistics are an important element in the communication of what is occurring in the criminal  world and students will learn how to analyse and assess this information 

The Irish Justice System

 Students will examine the various structures within which our society deals with crime and criminals in a practical  context including the Court System, Lawyers, Prisons and the Probation Service.


This topic includes the identification and classification of illicit drugs that are available in Ireland and throughout the world. It also examines the effects they have on individuals, their methods of use, their prevalence, production and marketing.


The concept of violence is defined and students will examine what this means in modern Ireland by exploring the various types of violent crime that exist including murder, manslaughter and assault.

Crime and the Wider Community

Students will be asked to examine and assess the role of the community in crime prevention. While the Gardaí are the main component of the State in this context, students will investigate whether crime prevention has a wider dimension that incorporates each and every citizen.

Organised Crime

This includes an examination of crime across borders and how Irish criminals now work out of many EU and global bases. In the domestic context students will be asked to assess whether the methods used to tackle organised crime, including the Criminal Assets Bureau (CAB), are working.

Crime and Young People

Students will examine the various methods used to deal with youth crime including the concept of restorative justice.The Children’s Court and ASBOs will also be discussed in detail.

Forensic Psychology and Criminal Profiling

An examination of the concept of Forensic Psychology and how it works; from basic theories and principles, through research, understanding and explaining results, to the actual application of psychological techniques and how they link to criminal theory. Students will also examine what is meant by criminal profiling, and how the use of scientific methods, logical reasoning, sources of information on people, criminology, victimology and experience or skill is employed to interpret the events that surround the commission of a crime.


This lecture aims to define terrorism and examines the main methods and strategies employed by modern day terrorists including the relatively recent concept of the suicide bomber. We will also examine who these people are and assess the reasons for the employment of these extreme methods.


This course is delivered over a ten week period, one evening per week, through lectures which promote class interaction and participation in what is a controversial topic that can generate varied and diverse views. The classes are animated, topical and extremely enjoyable. Healthy debate is encouraged amongst students and lecturers and student participation will greatly increase the learning outcome of the course.
