what is the geographic territory claimed by a gang
Gang Street gangs take over territory or "turf" in a particular city and are often involved in "providing protection", often a thin cover for extortion, as the "protection" is usually from the gang itself, or in other criminal activity. Many gangs use fronts to demonstrate influence and gain revenue in a particular area.[52]
