Maybe it's because I work in healthcare, but the idea of just saying "no, you can't have this life saving device" makes no sense. Dude was ready to hand over everything he had on him to just get the device. There was an incident at work where we noticed a man had fallen on the sidewalk just outside our unit, two of the nurses went to check on him while I stayed on the unit. They helped him get up and got him over to a bench. He did not want any help or an ambulance to be called but eventually we'd hear from the supervisor "technically it puts us at risk of liability because he's not our patient." Nobody was punished for it because nobody would really go and say "you see someone in distress, you do nothing." They went and helped and I made sure that should something have happened on the unit, I was ready to immediately respond.

I would imagine that Good Samaritan laws would shield the nurses that went outside because they went and assisted to the best of their ability, but I have no idea how the organization would be held liable potentially.
