During my training to be an NRA certified Range Safety Officer, the Instructor told us that anti gun anti freedom useful idiots were going to gun shows and when no one was looking sneaked live rounds into guns they were “looking at” hoping to cause just such an accident in order to advance their agenda.
I have very little doubt but what they prowl around gun shops as well.
Don’t put anything past these shills, and counter them with obsessive compulsive SAFETY procedures at all times!
The left has an Army of highly motivated shills out there, to include most of the “Students” in the academic gulags. If you are ever in a Gun Shop and see someone of college age hanging around, keep a close eye on them!
The gun shop really does need to do a root-cause failure analysis on this incident.
Somebody put that round in the firearm. They need to find out who and why, and why it was not discovered before the incident.
