I was once sweeped by a clueless grocery eater shopping for a shotgun at the big box sportsman store south of Austin. You better believe I made a scene. I don't give a rat's ass if you THINK the gun is unloaded or even if you are sure you cleared the chamber ... MORAN
NOBODY EVER POINTS A GUN AT ME WITHOUT GETTING A NEW ASSHOLE REAMED INTO THEM RIGHT THEN AND THERE. PERIOD.
I don't go to those big box sportsman stores anymore ... gun shows are where it's at ... my kind of peeps there.
Regarding the picture in the OP, I can guarantee that I would have been out of my car and in that "LEO"'s face ... consequences be damned. Yes. I know what I'm writing. CONSEQUENCES BE FUCKING DAMNED!
I guess it helps my situation here that most of the LEOs where I live are avid sportsmen and know how to handle a gun properly.
I've had to chew out a good friend who, when climbing into my pickup, swept his long gun barrel towards my feet at the brake and accelerator pedals. I made a scene then, too.
I have found that making a scene is the only way you can make an impression on an adult who obviously never received gun etiquette training as a kid.
"Common sense" used to be more common.
