The U.S. intelligence community is investigating micro-blogging tool Twitter as a possible tool for terrorists to coordinate attacks, according to a purported draft Army intelligence report posted on the Web.
The report--present by the 304th Military Intelligence Battalion and posted to the Federation of the American Scientists Web site--examines the possible ways terrorists could use mobile and Web technologies such as the Global Positioning System, digital maps, and Twitter mashups to plan and executive terrorist attacks.
