Sorry for being away and not finishing this out. It's been a busy week at the office. At any rate, what you may find interesting to know about the events described in this incident is that when the cars were out of the way, our "hero" was met with the image of the he saw running chasing after a small child who'd broken away from his mother (the woman) and was running across the parking lot, toward the street. Again, the point of the story and the exercise is determining whether or not you actually have enough information to act or whether or not continued observation might be what's warranted rather than direct action.
I like the fetal position plan. Might crap myself too just for good measure.
