This is ridiculous. The OP didn't even pull his gun. If I was the man approaching, and I had that kind of legitimate emergency, and I observed a man feeling threatened (he put down his bags and placed his hands as if to pull a gun) I would have put my hands out palms facing the OP, and said something to the effect of yo- hold up, my wife is having a baby can you call 911 for me? But, in reality, since I am not stupid, I wouldn't be wandering around a parking lot looking for help I would already be at a payphone, in the store, or driving to the hospital (or on a plane like Palin
Stop picking on the OP, he didn't do anything wrong, he did everything right, and seems to me the OP gave the other guy more credit than the OP is getting from you.
