In one of the cases a young boy is shot and killed by his mother while she ""switched off the safety on her Remington 700 rifle and the gun went off."" That is a very sad story indeed. However I don't allow folks in front of my barrel while I'm doing anything with a rifle. I was taught early in life all guns are loaded and what the heck is a safety?? Safe weapons handling is the only Safety, not a piece of metal in the system that might should could work.
Any rate check out what you own and whats going on. Stay Safe..
