Are there any girl gangs?

Yes, Experts say of the 600,000 to 950,000 gang members in the United States, female gangs make up between 10 and 15 percent. Although many female gangs serve as auxiliaries to male gangs, there has been a surge of female gangs that operate on their own. Because female gang members believe they must prove themselves to their male counterparts, they will use extreme violence against other female gangs or, in some rare instances, against male gangs. So they are just as dangerous.
