Gang Violence Case Study


For three generations, Long Beach, CA experienced gang violence that compromised the safety and well-being of its citizens. To address this public safety issue, the Long Beach Police Department (LBPD) launched a comprehensive injunction program to neutralize its gang threat.

The video describes how Laserfiche helps LBPD officers gain instant access to the information needed to make arrests from their patrol cars. Interviews with both Laserfiche CEO Chris Wacker and Long Beach City Prosecutor Doug Haubert are featured in the video.


  • Long Beach ranked among the nation’s top five cities for gang murder
  • State funding cuts resulted in prisoners being set for early release


The Long Beach Police Department deployed Laserfiche software to give officers instant access to the information and images they need to make gang arrests. Now, when a gang member’s name is searched on a patrol car computer, all of the most up-to-date intelligence on that individual pops up.

The department adopted a three-pronged approach to combating gang violence:

  1. Suppression of gangs by leveraging technology and data to strengthen law enforcement efforts
  2. Intervention by identifying at-risk youth and making a concerted effort to help them stay in school
  3. Rehabilitation by creating programs that help to move individuals out of the criminal justice system and on a path to gang-free life


  • 650% increase in gang arrests
  • 52% decrease in gang murders
  • Upgraded technology to strengthen law enforcement efforts across Long Beach

Tackling crime and preventing it is best achieved when all the relevant agencies and the local community work together

Local crime solutions

People often think of the police as the only agency involved in tackling crime. But crime and threats to community safety often touch people’s lives in complex ways and usually have multiple causes.

This complexity means that tackling crime and, crucially, preventing it from happening in the first place, is best achieved when all the relevant agencies and the local community work together to develop local solutions to local issues.

London is a uniquely diverse and complex environment and the capital’s 33 local authorities, who both know and democratically represent their communities, are uniquely placed to work closely with the police, local people, businesses and voluntary and community organisations to promote public protection and tackle crime.
