You said other people had stopped and the occupants of the vehicles involved were already out of danger. They didn't need you unless you are a trained physician or EMT and probably not even then.
I generally have a problem with CCW. My experience has been that folks who are carrying concealed, often interject themselves into situations where they are not only unnecessary but also bothersome.
I find this comment disgusting.
If emergency units are present, I agree you should stay out of the way, but when there are no flashing lights, people need to help others. Just because a couple people stopped doesn't mean they don't still need help (those who stopped could be 90yo and unable to do anything).
A couple months ago a woman drove her van into a pond not far from my house... her and her 3 daughters all died. It sickens me to know some people would keep driving and let them "call the cops or take care of it themselves."
I suggest anyone who feels this way check out the news article and look at the pictures of the little girls. They died in ~6' of water.
