From the Financial Transactions and Reports Analysis Centre of Canada, a helpful banker's guide to spotting "single-issue terrorists," which includes (apparently) abortionists and ecological extremists. It also groups attacks on property with attacks on people, and sales of books and literature with sales of false identification documents.
Counter-terrorism specialists define single-issue or special interest terrorist groups as being motivated by political and social issues and as using violence and criminal activities to further their agendas. Single-issue terrorists may include militant minority rights activists, abortionists, animal rights activists and ecological/environmental extremists. They believe that their legitimate cause morally justifies their extremist violent behavior in opposition to government action or inaction. Terrorist attacks include the use of bombs, such as mail and car bombs. Their targets are often research laboratories, clinics and individuals' property. Single-issue terrorist groups function domestically but have an international scope.
