My service makes it 100% the crews choice on l and s response. Up to the person whether not we transport l and s. We tend to not use l and s unless the patient is unstable/critical.
I have one on my rear windshield. It is only to ,ark my car for when I leave it on the side of the road to ride in on the ambulance. This notifies police that it belongs to someone on the crew, so the cops will not give a parking ticket.
The cops in my area respond to most of our calls for scene safety. For codes they help with CPR. All Leo's in our area are first aid and CPR certified.
During my ER clinical I went from helping a doctor reset a tub-fib fracture to sitting and listening to an RN complain about being overworked. He taught me a few things but spent way too much time complaining.

We are part vollie part per diem. There are always two people at the station, usually a medic and an emt/aemt. We do twelve hour shifts.
At My service we stay at the station when we are not on calls. We get to watch tv or do anything we want within reason as long as we can get on the truck in little to no time.
