Truth and reconciliation from Belfast to Cape Town
In a place once tormented by political violence, an extraordinary group has come together.
On a coach in South Africa, a former senior IRA man chats to a police officer whom his organisation once wanted too kill.
A top policeman from the Irish Republic and a former loyalist prisoner sit nearby.
This group is taking part in a peace-building experiment on a visit to South Africa to study policing and how to deal with the legacy of violence.
The trip was spearheaded by the Conflict Research Institute at the University of Ulster with the help of community groups and funding from Europe.
Journalist and broadcaster Fergal Keane joins the group as they meet witnesses from South Africa's Truth and Reconciliation Commission and asks how the demands of victims for truth about the past can be answered.
