There are many kinds of gangs, but whatever kind you community is dealing with, gangs spell trouble. They cause fear, destroy property, threaten or hurt peaceable residents, and drive out businesses. Parents can do a lot to prevent gang problems or top reduce gang problems already in place.
Gangs leave signs of their presence.
The odds are that the better you meet these needs, the less need you children will see for gangs. Spend some special time with each child. Do everything possible to prevent dropping out. Know about their friends and their friends' families. The best time is before there's a major problem.
