No, these people understand that you intervene at your own peril. I would not want to face a lawsuit from the family if I moved the man and caused more damage. I would stay with the guy to prevent further injury, but would not touch him.
Thank you John Edwards, et al.
I would not have tried to move the injured man but I would have called an ambulance and sat beside him and reassured him that help was on the way until it came. I have done that BTW, several times in my life for accident victims. There is something wrong with these people.
