Book excerpt: Many people in America think that gang violence is concentrated in the inner cities of New York, Los Many people in America think that gang violence is concentrated in the inner cities of New York, Los Angeles and other isolated metropolitan areas. They are mistaken, says Loren Christensen, a veteran Portland, Oregon, gang-enforcement officer. After completing Skinhead Street Gangs, Christensen went back to the streets to see what's happening with gangs, and what he found scared the hell out of him! He found that gangs are everywhere and are here to stay - in the big cities and small towns, in the suburbs and the rural areas, on both coasts and in the heartland. His research also showed that gangs are equal-opportunity destroyers. Their members - and victims - are white, black, Hispanic and Asian. His most disturbing discovery was that gangs are nastier than ever. Ten years ago gangbangers fought with fists, clubs and pistols. Now they have lots of incredible firepower, and they don't think twice about using it. Here, Christensen lets gang members, former gang members and street cops tell you in their own words how gangbangers think, why they are so violent, who they target and what (if anything) can be done to curb the growth of gangs in America.
