Police create gang units, prosecutors build gang cases, and politicians pass laws prohibiting all manner of gang activities. Nothing has worked. Some activists coo over gangs, mistaking them for nascent community groups. That has not worked either. We have been so wrong about gangs, for so long, that an entirely new approach is needed. We have to start over and refocus our efforts not on gangs but on gang violence. If a gang or gang member is violent, they deserve our anti-violence attention. If they are not, our time and energy are better spent elsewhere. With gangs, the issue is not the group's identity; it is the group's behavior. Gangs are not the problem; gangbanging is.
