I Know, basic stuff, but it is what it is.
The jackwagon that touched off a round did not look in the chamber AND pulled the trigger...accidentally, or knew exactly what he was doing.
Also good points.
I’m not even sure why the trigger would be pulled at a gun show, much less with the barrel pointing in a direction that were there a round somehow in the chamber it would cause injury on discharge.
I know when I’m cleaning or inspecting a weapon, should the weapon be cocked at any point, once I am certain that there is in fact no round in it, I will then aim that weapon at a target such as the ground outside or some wall or object that I know could absord an errant shot with no injury to a human or animal, and then discharge that spring tension.
There does seem to be some suspicious gun handling going on here or in the very least some very dangerous noobery.
