Which of the following is NOT one of the principles of public safety communications?

The principle that is NOT part of public safety communications pertains to environmental protection. Public safety communications primarily focus on the coordinated response and communication among entities like law enforcement, fire services, and emergency medical services. These principles ensure effective and efficient communication during emergencies, enabling responders to manage incidents and protect the public.

While environmental protection is important and can be related to public safety, it is not a core principle of public safety communications in the same way that the other three options are. Law enforcement, fire services, and emergency medical services are integral parts of the emergency response framework, and effective communication among these services is critical for public safety operations.
