Step-by-step explanation:
The option that is NOT a valid assumption when developing a plan for response to a civil disturbance is: Option 1: All disturbances will follow a predictable pattern. This assumption is not valid because each civil disturbance can be unique and may not follow a predetermined course of action, making predictability difficult. On the contrary, expecting property damage, prioritizing public safety, and maintaining communication with the community are all realistic and critical considerations when planning for a response to civil disturbances.
In any plan for response to a civil disturbance, communication with the community is vital for ensuring public safety and coordinating efforts. It helps disseminate important information, address concerns, and promote cooperation and collaboration.
