@Leslie killings definately has an impact on any country not just Barbados. Loss of lives, injuries, battling with medical bills, loss of income for injured people in gun shoot outside, loss of physiological needs for families who lost their bread winners, loss of economic growth, mental health issues for those who lost loved ones, lack of medical services, etc

It all depends on what your variables or patterns depending on what method you chose to apply for your study. However, this is very interesting and i recommend you use a mixed methods approach with an exploratory sequential mixed method.
