Serious crimes-such as violent extremism, political violence, organized crime, and corruption-fuel violent conflict and thwart peacebuilding efforts. Fragile states with weak institutions and governance are unable to stem the tide of threats that serious crimes pose to peace. The consequences are all too evident across the globe: countries engulfed in political turmoil, conflicts that spiral into devastating wars, and tides of refugees fleeing instability and violence. Fighting Serious Crimes: Strategies and Tactics for Conflict-Affected Societies is an invaluable resource for anyone battling serious crimes in societies seeking to avoid conflict, to escape from violence, or to recover and rebuild. Packed with practical guidance, this volume includes real-world examples from more than twenty of today's conflict zones, including Libya, Yemen, Iraq, Afghanistan, Somalia, and Colombia. All the major challenges are covered, from initial assessment to legal and institutional reform, investigation to prosecution, criminal intelligence to witness protection, the use of international tribunals to the role of international military forces. The volume draws on the firsthand experience of dozens of practitioners, distilling what they have learned into clearly organized and highly readable text that is supplemented by checklists and sidebars that help readers conduct assessments, identify international and regional legal instruments (such as treaties), and complete a host of other key tasks.
