Street gang violence has become a major public health problem in the U
nited States, especially in the inner cities. Firearms are the most co
mmonly used weapons in violent street gang activity. Walkup and drive-
by shootings that result in injuries are two of the most common crimes
committed by members of violent street gangs. To prevent injury and d
eath from gang violence, the root causes of violent street gang activi
ty must be alleviated, and the relationship between firearms and gang
Violence must be addressed.
