His brother, Ross, was a critic of British government policy in Northern Ireland, and called for a "tougher" response by the Army against Irish republicans. Ross was shot dead by the Provisional IRA in 1975 at his home in Middlesex after offering a reward for information leading to the apprehension of those carrying out a bombing campaign in London at the time. Following Ross's murder, Norris co-founded the right-wing political organisation the National Association for Freedom (now The Freedom Association) in 1975. This organisation initiated legal challenges against the trade union movement in the UK, Campaign for Nuclear Disarmament (CND) and the European Economic Community (EEC) in Brussels. The organisation states that the work it undertakes falls within the following Eight Principles of a Free Society: Individual Freedom, Personal & Family Responsibility, The Rule of Law, Limited Government, Free Market Economy, National Parliamentary Democracy, Strong National Defences and a Free Press and Other Media. It continues its political activities to this day.
