like to murder me. I know that that organisation will go on murdering other people until they are finally defeated. It is my belief that in spite of IRA/Sinn Féin's strategic cunning, and no matter how many people they kill, the people of the Irish Republic expect, because they have been told so by John Hume, that there will be peace. There may come a time when their patience runs out. If that were to happen there would be no place for IRA/Sinn Féin to hide. We must work tirelessly to bring that day forward. O'Callaghan lived relatively openly in London for the rest of his life, having refused to adopt a new identity. He was befriended in the city by the Irish writer Ruth Dudley Edwards, and worked as a security consultant, and also occasional advisor to the Ulster Unionist Party on how to handle Irish Republicanism in general, and Sinn Féin in particular.

A 1997 article in An Phoblacht alleged that O'Callaghan "has been forced to overstate his importance in the IRA, and to make increasingly outlandish accusations against individual republicans".
