Several cities have recently adopted civil injunctions as a means to reduce gang violence. To evaluate the effectiveness of such injunctions, I develop an extensive database of neighborhood-level reported crime counts from four police jurisdictions within Los Angeles County. I construct two different comparison samples of neighborhoods not covered by injunctions to control for underlying trends that could cause one to overstate the injunctions' effects. The analysis indicates that, in the first year after the injunctions are imposed, they lead the level of violent crime to decrease by 5-10 percent. Copyright 2002 by the University of Chicago.
