Final answer:
Communication centers should maintain complete records for all calls to ensure comprehensive data collection and inform policies, while taking steps to minimize biases and ensure representation.
Step-by-step explanation:
Complete and accurate records should be maintained at communication centers for all responses, not just for emergency or criminally related instances, or from areas with high call volume. Maintaining records for all responses allows for a comprehensive understanding of the pattern and nature of calls, which can inform future actions and policies. Special considerations must be taken to ensure that data collection is representative and free from biases due to factors such as not everyone having a telephone, cell phone numbers not being listed, and individuals being away from home during call times.
