Transnational crime and criminal networks have grown to such proportions that they have become a global problem. Large-scale crime, terrorism, insurgency, and piracy are blending into transnational criminal networks, capable of holding ground and challenging the power of the state, and threatening the basic fabric of society. Overcoming transnational crime requires the United States to merge domestic and international strategies. Domestically, the U.S. must do more to enable local police to integrate their effort and to develop, analyze, and share intelligence on narco-gangs and the cartels.
