In comments, commenter "P" tells us the apocryphal story of scary black men secretly loading guns at a gun shop:
There was two patrons who were very odd acting and kept handling every shot gun on the rack furthest from the counter. Even the clerk noticed it and got my attention and I walked back to that area of the store. As I approached they seemed quite furtive and after a couple of whispers left the store. The clerk followed them out and had a conversation with them and they took off to a bus stop. When he returned I was trying to put the guns they had been handling back in order. As is my custom every gun I touch was opened to check the action. The third or forth gun I opened had a live round in the chamber. I immediately called the clerk over and we went through every gun on the rack. These a-holes had loaded nine shotguns intentionally and put them back in the rack.
Got it so far? Bad, bad black men sabotaging the sanctity of white gunloonery. The story continues:
To blame the gun shop owner would be ridiculous, he was called names by the two hoodlums who had done this as they were leaving and called a racist for singling them out. Fiendish want to cause an accident? Were they planning on returning and using the loaded guns as tools in a robbery? No one knows but they had intentionally created a deadly accident waiting to happen.Whoooooa! It's wrong to blame the gun shop owner??? IOW, "P" is saying that guns owned by the gun shop owner aren't the responsibility of the gun shop owner. I guess once your firearms are touched by scary black men, they are transferred from your circle of accountability. But what's a good gun story without a safety reminder?
This is why the four rules are so absolutely critical to follow no matter what the situation. Guns don't go off unless someone pits the booger hook on the bangswitchApparently, one of the Four Rules is that your firearm stops being your responsibility when touched by another.
