Northern Ireland has experienced sectarian violence since 1969. By the early 1980's the RUC had been disarmed, rearmed, reorganized, and greatly enlarged. British military involvement has been high since the middle 1970's, but primary responsibility for policing and counterterrorism has been gradually returned to the RUC. By 1984, it was one of the most experienced counterterrorist police forces in the world. Nearly all officers wear flak jackets and carry holstered revolvers. Many carry automatic weapons. Mobile units provide backup to the patrols. The intelligence and investigative efforts are also active. The Force Control information Center also has a major antiterrorist role. The RUC has relied increasingly on technology, including computerized record systems, closed-circuit television, aerial photography, adapted body armor, and surveillance equipment. Despite these efforts, the rule of law will come only with changes in politics, the economy, and attitudes. The RUC is a much better police agency than it was 10 years ago and will probably continue to place a major emphasis on dealing with the continuing conflict in Northern Ireland.
