That seems to be the story in a lot of places today. I saw an interesting "disagreement in a Walmart parking lot a couple of days ago. Two guys arguing as to who was in the right when their pick-ups bumped each other. Both guys armed, stood face to face, and released the safety strap over their guns, so they were ready to draw.
Fortunately the cops got there before they went any further. This is something we should worry about down here in Texas.
