We'd like to see your organs.
A patient having a heart attack calls 911, and an ambulance rushes to the scene to save a life. A second ambulance, with the words "Organ Preservation Unit" stenciled on the side, arrives a little later in case the first crew is unsuccessful. Like anything with organ transplantation, it's a concept with complicated ethical, logistical, and public relations considerations, but an interesting plan nonetheless. I still vote for a national opt-out policy instead.
