Abandoned houses are a favorite target for graffiti, but even occupied houses and local businesses do not escape. The majority of residents in a gang area who are unable to move away, live in constant fear. In many cases, youths are not actively discouraged from gang involvement by their parents. Often parents are unaware that their children are engaged in gang activity. Gangs generally identify themselves by a name derived from a street, neighborhood, or housing project where they are based, or from a rock band they like, or a cult they follow.
Gangs are predominately territorial.
Each gang has its own turf and graffiti marks its boundaries. Anyone not belonging in the area and who resembles any rival gang members may become the subject of attack. Most gang members dress in the same manner. The uniform of some local gangs is easy to recognize. Gang members also like particular brands of shoes, pants or shirts.
