9.05.010 - Findings.

The city council finds:

(a) The majority of burglar and holdup alarms to which law enforcement responds are false. Such false alarms result in an enormous waste of manpower. That there are such a large percentage of false alarms as may lull law enforcement officers into a sense of false security. In responding to an alarm, they will probably assume it is a false alarm and may be wounded or killed by criminals at the location.

(b) Alarm systems which automatically and directly dial any emergency phone number are very prone to be activated by current failures or other events having no connection with criminal activity and tie up such emergency phones making them unavailable to receive genuine emergency calls.

(c) The danger to citizens through emergency response created by false alarms is unnecessary and hazardous.

(d) The unnecessary waste of tax dollars through responses to false alarms must be eliminated.

(e) False burglar and holdup alarms have created conditions causing danger and annoyance to the general public.
