The incident in Kawhia where a police officer was beaten needs a great deal of examination as to what happened and how it can be prevented.
But one of the elements of that nasty incident was the calling in of firefighters to help with police work.
These two emergency services have long worked side-by-side, often attending the same events, but the calling in of firefighters to back up police needs to be looked at closely.
Firefighters are not a de facto police force. They do not have the training nor resources to act as such. If the Kawhia policeman needed help, it should have come from the police force.
In emergency situations it is patently obvious that they may be called in. So will civilians for that matter.
