Over the past 25 years the State of California has instituted one of the largest criminal justice crackdowns on young people in the United States with prison spending growing by 794 percent. This research guide, produced by the Data Center, provides information to identify critical links between government institutions, politicians, and corporate interests that are working together to maintain a criminal justice system that targets and incarcerates youth at such a high rate. The guide is organized by research topic containing listings of California government agencies on the State, county, and municipal level. The guide is useful for youth groups conducting research on local and State police forces and corrections, or investigating the demographics of those being targeted for arrests and imprisonment, as well as for those helping to fund the Prison Industrial Complex. The guide is divided into five sections: (1) investigating the police; (2) prison expansion; (3) criminal justice demographics on who’s getting locked up; (4) budgets and campaign contributions; and (5) additional criminal justice research resources. Several appendices include: sample public records requests, tips on filing public records requests, glossary of government agencies and departments, and California Juvenile Justice System map.
