The U.S. has relied upon deportation as a primary tool to break up street gangs because a large percentage of street gang members in the U.S. are in the country illegally. This book illustrates how deportation has been ineffective at reducing the spread of street gangs in the United States. It also describes the adverse effects that the deportation of gang members has had upon Mexico, which receives the dominant portion of deportees from the U.S. Finally, this book draws conclusions concerning the framing of the gang problem, and recommends steps to be taken and areas for further research to help solve the gang problem and make deportation a more viable element of the solution set.
