A Law Enforcement Sourcebook of Asian Crime and CulturesTactics and Mindsets [PDF ebook] 

Even in multicultural North America, few whites, blacks, or Hispanics have extensive experience or understanding of Asian culture. For experienced police officers, intelligence analysts, correctional officers, and prosecutors, the problems of cultural differences in behavior remain complex and problematic. This book addresses these specific law enforcement problems, and supplies law enforcement professionals with information and strategies for easier arrests, more accurate intelligence, more successful prosecutions, and fewer problems during incarceration.
