pyschopuppy1, I understand what your are saying but I lump friends and neighbors the same as family. An assailant though is another story. I don't care who the assailant is I will not be providing first aid to them. I will call 911 and get the appropriate medical crew on the way along with the police.
As far as accidents on the road goes, I have been there. In the early 1980's I was a certified Emergency Medical Technician as well as an armed security officer. I was returning from a range session at an NRA Security Firearms Instructors School when there was an accident on the highway. While wearing my duty gear I stopped and administered first aid until a rescue squad could arrive. Local county police showed up first. I advised them I was an EMT and they let me tend to the injured until the squad got there.
