With what's going on in todays society, protest, riots, unprovoked personal attacks on people, I'm afraid I would probably return fire. It's a shame that this is what the world has come to now. :-( But I'll have to say it would depend on the location I would be in. Big city or a small rural area, time of day, what has been happening lately in the area I was in. Many things to consider in a short period of time, makes this kind of decision difficult.
