Over the past 20 years, the problem of threat groups (gangs) has grown exponentially. Today, communities across the country face a gang population that has crossed all socioeconomic, ethnic, and racial boundaries and now permeates American society. The world of threat groups (gangs) can become very complex. Knowing this, it helps to divide these groups into some basic categories that will form a firm foundation to learning and understanding. In this program we will explore all of these categories, giving you an opportunity to find out what they are and what threat they pose to our agency.
