The original prison gang, the Mexican Mafia, is the fastest growing prison gang in the United States. The authors illustrate how this prison gang uses influence, power, and violence to control an army of over 40,000 street gang members across the nation and countless more internationally. Learn about the special relationship this group has with Hispanic street and prison gangs, Mexican drug trafficking organizations and the constant battle over money, power and control. The Mexican Mafia continues to expand its transnational criminal activities and will continue to diversify until the criminal justice system becomes more informed.
