This document provides an introduction and preface to a conference on countering terrorism held on February 28, 2002 at the FBI Academy in Quantico, Virginia. Over 70 law enforcement personnel and academics met to discuss scenarios related to counterterrorism challenges. Participants dispersed into small groups to discuss the scenarios and questions developed beforehand. The goal was to integrate practical experience and theoretical perspectives on issues like intelligence analysis, risk communication, and building ties between law enforcement and Muslim communities. The conference aimed to apply expertise to scenarios and raise additional questions to further address counterterrorism challenges.
