I remember a story on some gun forum told by a LEO who responded to a call from a distraught vacationing family who found an "explosive device" in their rented minivan. When he arrived on-scene the family was huddled far from the van and trembling in terror. The "explosive device" was a shotgun shell rolling around in the van. I can't recall if it was even a live shell or an empty one, but they were all certain it would blow them to bits.
I'd love for that poster to tell the tale again. As a Public Safety announcement if nothing else. No idea where I read that, but it illustrates the levels of naiveté that sheeple can be driven to. Like kids drawing guns on paper, playing cowboys and indians with finger guns at recess, or (horrors!) gnawing a pop-tart into the "shape of a pistol".
