Agree completely. An example is Good Samaritan laws. In general, if you stop at, say, a car crash and try to render aid, you're immune to civil suits if your attempt doesn't help, or makes things worse, so long as you were doing your best to help.
Those laws generally do not apply to EMTs/Medics/Nurses/Drs. And it has always struck me as more than a little unfair that an LPN who works in a nursing home is held to the same standard as me.
But Foot in Mouth disease is also real... A new medic on one of our area ambulance services told a guy at a crash to get out of the way, because although he had reduced a femur fracture (and in doing so restored blood flow to the persons foot...) he was "doing it wrong". The person the medic reprimanded is the head of Trauma Surgery here...
