From a purely economic standpoint, trying to limit the growth of gang activity via restrictions placed on gang clothing is a viable option. However, schools must also address the legal issues of whether schools can or should restrict gang clothing and how to restrict gang clothing without infringing on students' constitutional rights. Judicial decisions have established that schools must substantiate the existence of a problem within their jurisdiction before restricting gang-related clothing. If a school board cannot prove that a gang problem exists, justification for gang clothing restriction is considerably weaker. Policies must be carefully written. A number of school districts are requiring school uniforms and have developed other programs, including Project COURAGE in California, designed to reduce juvenile violence and provide alternatives to gang membership.
