Following a review of the scope and seriousness of gun violence among juveniles, particularly in urban areas, this study profiles the black market in gun sales that is a primary source for juvenile gun purchases. The author concludes that traditional gun-control laws, which are designed to regulate the transfer, possession, carrying, and use of firearms, have not been very effective. The laws and those who enforce them are overwhelmed by the realities of the gun market. Traditional gun controls cannot prevent the workings of robust black markets in firearms. The author proposes that the youth gun market be disrupted through custom-designed local strategies that are developed and implemented primarily by local authorities. Such strategies must be comprehensive in using mutually reinforcing tactics tailored to local circumstances. Strategies must be based on accurate information regarding youth gun markets. The author suggests how such information can be obtained. Examples of local gun control strategies are described, along with strategies for reducing the fear among youth that contributes to their purchasing of guns. 19 footnotes
