Wallace joined the RUC in 1955. He was appointed Deputy Chief Constable in June 1992. In July 1992, as Deputy Chief Constable (Operations), Wallace was given a new role in co-ordinating counter-terrorism operations run by the police, the army and the security service, MI5.
- He will work closely with Major General Ian Freer, commander land forces in the province; the head of the RUC special branch and the director and co-ordinator of intelligence, who is a senior MI5 officer. The four men will serve on the Province Executive Committee, set up in April last year, which Mr Wallace will chair.
In February 1994, Wallace rejected an Amnesty International report which claimed that the security forces were involved in collusion with loyalist paramilitaries.
- He said 230 loyalists were charged with terrorist-type offences last year, compared with 137 republicans. "Do these facts suggest collusion with loyalists? What utter nonsense. Does this suggest collusion or support any allegation that the security forces are neglecting their duty of protecting the Catholic community? Again, what utter nonsense," he said.
Friends of the Union
In February 2003, Wallace backed the 'Stormont Principles' initiative launched by the Friends of the Union.
- Two UUP MPs, Jeffrey Donaldson and David Burnside, have already signed up to the Stormont Principles, which will also concentrate on securing stability and a lasting peace in Northern Ireland, with total disarmament and disbandment of all terrorist organisations, republican and loyalist, the only way to achieve this.
