Accidental shootings, especially those involving children in any way are getting a lot of attention these days and deservingly so. We talk a lot about the Four Cardinal Safety Rules. I wonder if Jeff Cooper were writing those rules today if he wouldn't have included a fifth rule. Something like; Rule #5 - Always restrict children and other persons from accessing your firearms without proper supervision. In the past I have always stressed this point after I teach someone the four safety rules but going forward I think I will just throw #5 in like it's always been there. Comments?
