A study of nearly 40 years of terrorist attacks on U.S. soil reveals that nearly a third took place in just five major urban "hot spots": New York, Los Angeles, Miami, San Francisco and Washington, D.C.
The report, by researchers for the National Consortium for the Study of Terrorism and Responses to Terrorism, found those cities, along with Chicago and Seattle, experienced the most attacks motivated by causes, ranging from left-wing and right-wing agendas to religious and nationalist ones, as well as some single-issue rationales. Their findings were based on information in the consortium's Global Terrorism Database.
