I work nights as a security guard. This happened at work, it wouldn't have happened under any other circumstances because I wouldn't have involved myself even to the extent that I did if it hadn't been required by my job. The place I work at is in the middle of an industrial park. It's surrounded by warehouses. None of them were open at the time. I was walking the fence line when I noticed a car randomly cruising the parking lots of the warehouses. Other than making sure they weren't scoping out my site they really weren't my business. So I was only keeping an eye on them as they got closer to my area. They must have noticed me because they car pulled up next to my fence and the passenger said something to the effect that not minding my own business was a good way to get myself shot. They gave me the stink eye for a second, then they took off. I was armed. I did not engage the passenger other than to say OK as I was backing up. I did call it in to the police but the car was long gone by the time the cops showed up. When they engaged me they had my undivided attention. When the passenger made the shooting comment I put my hand on my gun and I made the decision that if his hand came up into the window I was going to draw. ( there wasn't anything I would consider "cover" close enough to get to) and if there was any kind of weapon in his hand I was going to shoot. My question is at what point did I have the right to assume he meant what he said and that it was a legitimate threat? I have coworkers that would have had their gun out as soon as he said it. Some would have drawn discretely as soon as they pulled up to the fence. In general I wouldn't even touch my gun unless I could describe a specific action the other person took that convinced me an attack was imminent. I have no idea if the guy had a gun or not but he threatened to shoot me. At what point do I get to take him seriously?
