I suspect some tongue-in-cheek there. Although, having been a ward librarian, there's some truth to that, and my raised-LDS husband agrees. Heavy use by people who aren't exactly experts might be relevant. In the ward I was librarian in, the Bishop and one of his counselors were county sheriff's deputies, and the EQ President was a Highway Patrol officer (DH and I were friendly with him and his wife). One day the copier was being a bit more of a pain than usual, and the EQP walked in. I jokingly asked him if he had his gun handy. The Bishop was right behind him, and told me he'd seen the EQP shoot and that the copier was totally safe.
