the firetruck goes on calls here becuz it has additional medical equipment that does not fit on the ambulance truck, and yes the police also come on all ambulance calls, BUT calling it in as an ambulance call sets a different tone for the incident. When you call police and term it a police issue, typically the mindset is that there is a crime being commited, and probably a victim and a criminal and expectation of charges being filed. If you tell dispatch you want an ambulance and call it a medical emergency, then the tone of the call in the eyes of the responders is that someone is ill and needs help. When the authorities arrive, for a "medical call" they usually are not pysched up in the same mindset and are not especially looking for a criminal or to file criminal charges against someone.
