The officers volunteered to take part in the study and complete two interviews, one with a psychiatrist and one with a Home Office researcher. The interviews focused on demographic information, firearms training, the event, the immediate aftermath of the incident, the reactions of families and friends, and effects on behaviors and feelings. Results showed that both the immediate and long-term reaction patterns were similar to those reported in American studies. The majority of those interviews had little difficulty in coming to terms with taking a life. Incidents involving shootings of civilians or offenders who used a fake weapon were more difficult for the officer to resolve. Findings indicate the need for immediate psychological support, confidential counseling, a delay in the formal investigations, social support outside the police service, and support to the family.
