Always a tough one to call and I'm not sure what I would do until in that situation. I actually just discussed similar situations with my wife the other day. Being a CCL holder my first responsibility is me and mine. The police are for those who choose not to defend themselves IMHO. I have not sworn to protect anyone but me and mine. That said, I generally have the "Good Samaritan" spirit as I am in the medical field and more often than not find myself in situations that I instinctively become a first responder to helpless people even though thats not what I do in the medical field. Praise God that the man from the story stopped for this woman and son and that it worked out in their favor. It's just to hard to say with certainty what I should do/will instinctively do if I am ever in such a situation.
