Hey, some friends of mine have managed to assemble a database drawing on open sources, starting to support Congress and Federal agencies. This is the kind of tool professional and citizen journalists can draw upon for stories… and might be a serious resource for people fighting the bad guys:
The Information Project www.theinformationproject.org currently represents the world's largest, 100% searchable public terrorism database. The body of work details some 5,000+ named terrorist groups and aliases and covers some 70,000+ terrorist events ranging from the historic period (pre-WWII) to the present. (FYI: Less than 2% of our material is currently available on-line.) To date, our "client" list includes members of Congress, the State Department, the intelligence community, investigative journalists, researchers, individuals involved with related non-fiction projects, and other interested parties. Recent products include: "Aviation Hijacking Weapons Used 1931-2004" and "Issues Related to Al Qaeda and Bio-Chemical Warfare".
Note that the system is still a work in progress, very committed.
UPDATE: their hosting service is having problems today…
