What will police do?
When police officers arrive at a domestic or family violence incident their first priority will be the safety of the people involved.
Police are allowed to enter a residence when there is*domestic violence occurring and search the premises where the domestic and family violence incident occurred. This ensures that any people remaining at the property are safe from any further harm and violence and also to obtain any evidence necessary to ensure appropriate action is taken.
IMHO all people employed by the government are aware of the amount of paperwork involved in their job. I assume if they did not follow procedure their paperwork would be more time consuming than not ascertaining all people are safe.
