Mission Statement

The Law Enforcement Mutual Aid Bureau is responsible for providing law enforcement mutual aid to law enforcement agencies in the event an emergency occurs and the reporting jurisdiction determines that it is beyond their control.

California has had more than its share of man-made and natural disasters, civil disturbances and other significant events requiring large numbers of law enforcement personnel and equipment. Our ability to respond professionally and efficiently has proven not only cost effective, but also has saved lives and protected property. The Law Enforcement Mutual Aid system has been used successfully for many years. Notable events involving use of this system include:

  • Freeway Complex Fire
  • Station Fire
  • Watts Riots
  • Berkeley Civil Unrest - People’s Park
  • Huntington Beach “Surf” Riot
  • Loma Prieta Earthquake
  • Northridge Earthquake
  • Oakland Fire - East Bay Hills
  • Los Angeles Civil Unrest
  • Polly Klaas search

The Law Enforcement Mutual Aid Bureau derives from the California Law Enforcement Mutual Aid Plan, which is on-going cooperative effort among law enforcement agencies designed to provide an effective and organized response to a wide range of emergencies. Its comprehensive structure facilitates mobilization of law enforcement resources into a cogent response organization for addressing critical incidents including floods, fire, earthquakes and civil disorder.
