I was the victim of an attempted robbery in NYC. I had fired a pistol before, so when the robber threatened me with one (which he may or may not have had) I did some mental calculations and came to the conclusion to run, hard, in the direction where there seemed to be the most people. If he had a piece on him, by the time he drew it from his hoodie and aimed, I would be far enough away to make an accurate shot difficult... and if he missed he might hit someone down the road. I calculated he wouldn't be stupid enough to risk it.
