I noticed that Emory University (here in the USA) is offering a 6 week online class titled Understanding Violence online for free (via Coursera).
Note I have no affiliation with Emory or Coursera and have not taken this class but I have taken some of the statistics class via Coursera and have found them very useful.

About the Course
Violence is a leading cause of death, disability and health care use in the United States as well as worldwide. Although significant progress has been made in the last few decades, there remains a great need to further reduce the frequency of violence and its long term effects. Violence causes approximately 50,000 deaths each year and over 2.5 million injuries in the U.S. each year, with an estimated annual cost of $70 billion. Furthermore, violence does not occur in a vacuum; the consequences are also felt through other medical conditions and health behaviors and individuals, families, and communities affected by violence are often irreparably altered.
Violence is a complex problem and can only be understood and reduced though a multidisciplinary approach. The course will cover the epidemiology of violence; roots of violence including biological, psychological, and social causes (e.g., economic deprivation, religious factors); specific types of violence; media and the arts portrayal of violence; the business/economic impact of violence; physical and mental consequence; and ways to control and prevent violence in our communities, including criminal justice and public health approaches. Through these perspectives, the course will deepen our understanding of violence in local, national, and global contexts.
Upon successful completion of this course, students will be able to:
1. Demonstrate knowledge of the problem of violence in the U.S. and globally, as well as the long-term effects.
2. Analyze the causes of and associations with violence from a multidisciplinary perspective.
3. Explore different solutions and programs for the prevention of violence. Course Syllabus
