Personally, I'd call 911 on the cell before I ever left the car. The neighborhood and time of day would determine whether I left the car to render aid, or simply sat in my car and waited for help before leaving the protection of my vehicle. Being a licensed nursing assistant, I am bound by law to render what aid I can, under threat of losing my license if I refuse to do so. BUT, this scenario has been used as a ploy to get people to stop, then suddenly the "victim" is fine, and engaged in either robbery, rape, and or car jacking. I tend to trust no one in this day and age.

Depending on the area of town, this could be a setup.

 

1.  Do a threat scan of the area.  A 360 trun with lights on high beam at night, if possible to flushout any obvious folks.

2.  Call 911 to make sure it is called in.

3.  If the victim looks for real, secure vehicle, approach with care and gun drawn until you can verify for 911 operator.

4.  Maintain situational awareness when approaching.

5.  Verify victim status and report to 911 operator.

6.  Render aid if you can until police and parmedics arrive.

7.  Maintain 911 contact.

8.  Make sure the 911 operator and responders know you are a CCW holder.

9.  Make sure you don't have the pistol in hand when the cops arrive because: (1) you can't be sure the 911 operator told them everything; (2) cops will assume you are the bad guy if they see a gun displayed; (3) sound off and tell them you have a mugging victim and you're a CCW holder.

 

Be prepared to answer a lot of dumb questions.

 

I think MasterGunner covered it pretty well. Ditto.

Hell yes I'd stop and help, first thing would be a 911 call on my cell phone before I ever exited my car, then I'd do what I could till help arrived.  I'd probably leave my weapon holstered, wouldn't want to traumatize the victim here, but you can bet my senses would be very aware, and my hand would never be far from my pistol, just in case I had to draw it quick.
