10.100.010 - Findings.

The City Council of La Mesa finds that the volume and frequency of falsely activated security alarm systems is due to inadequate installation, poor maintenance and employee error, resulting in a growing danger to the health, safety and welfare of the residents and visitors of the City of La Mesa. Furthermore, alarm system activations are a high priority police call for service, resulting in a swift response involving two or more officers, who are then out of service for extended periods of time, and requiring the drawing of weapons. These elements increase the danger to the police officers and public, interrupt other police services and public activities, and are a serious drain upon limited police services and equipment needed at other locations. This volume and frequency of falsely activated security alarm systems is a condition which has persisted so as to become an increasingly hazardous public nuisance.
