Re:What would you do?
I can sit here in my recliner and know exactly what I would do: Drop (ideally behind something), look around to determine where the shots are coming from, then get to a safer location (probably crawling to stay out of the line of site of the shooter).
However, it totally depends on who is around me. I was in a situation a few years ago where I was in a store in a strip mall and someone in the parking lot was having a shootout with the police. I immediately threw myself between the gunplay and the small child that was also in the store. I don't say this to make myself sound like some kind of hero, but because I know if I had been at LAX and had there been a child near me, I can virtually guarantee that's what would have happened again. If there were no kids, I honestly can't tell you what I would do...but I'd probably hide behind something, freeze, and wet my pants.
