LADA CJI About Us

Los Angeles County District Attorney Steve Cooley established the Criminal Justice Institute (CJI) in 2007 to provide high-quality training opportunities to law enforcement professionals through his staff of nationally recognized experts.

CJI serves as a regional training center to assist prosecutors and peace officers by offering practical training programs and materials to enhance the investigation and prosecution of criminal cases.

The Los Angeles County District Attorney’s Office has an established reputation for providing some of the nation’s best trainers in specialties such as DNA evidence, asset forfeiture law, foreign extradition and animal cruelty cases.

Through CJI, the Office shares the legal knowledge and experience of its deputy district attorneys and investigators with law enforcement officers. CJI trainers bring together top criminal law practitioners and scholars to advance public safety.

CJI has partnered with various local, state and federal agencies and organizations to meet current training needs, both basic and advanced.

Thousands already have completed CJI seminars on such cutting-edge issues as high-tech crime, search and seizure and the prevention of elder abuse and truancy.

CJI is quickly becoming recognized as a leading source of premier continuing education and professional development for law enforcement and other criminal justice system professionals.
