While the report claims this the shooter claims it was a prank gone wrong. It sounds more like homicide to me. Not sure which level.
It seems that the owner of a gun store bought a replica BB gun (airsoft?) and put it in the display case. He then claims he accidently picked up the wrong gun, pointed it at an employee as a prank and pulled the trigger.
The firearm was loaded and he killed the employee.
Any prank that starts with a firearm is a bad idea. Any prank that starts with a replica firearm in a situation where it is likely to be perceived as a real gun is a bad idea. Any prank that violates the four safety rules is a bad idea.
What the hell was going on that there was a firearm in a display case with a live round? At all of my LGS, even the ones I don’t like, nothing goes back in the case until it has been cleared. My LGS takes the firearm out of the case, clears the weapon, shows me that it is clear, passes it to me, I clear the weapon. We continue to follow the four rules. We follow the same procedure handing it back and it doesn’t go back into the case until it has been cleared and wiped down.
But OSHA is treating this as a safety violation: “The business failed to furnish a place of employment which is free of recognized hazards which may cause death or serious physical harm.”
