Unless there is a problem with a specific gang, this should suffice for establishing a proactive program . CITY gangs are usually formed based on territory. In a city setting, when a few gang members are identified, others who live in the same area are likely to be members of the same gang. In rural areas, gang members may travel several miles to be with fellow members. In either setting, gang members will tend to associate with each other to the exclusion of non-members.
Association is, therefore, a prime indicator of gang involvement.
The next indicators are grouped together because they should be used in conjunction with each other.
