Jack:
Thank you for posting that article. It serves to remind us all of one of the essential aspects of gun safety.
There is a story about the legendary Colonel Jeff Cooper having once had an accidental (negligent) discharge of a handgun he thought was empty. Intending to "dry fire" it using a water meter outside a window of his home as a target, as the story was told, he took out both the window and the meter. With a look of surprise on his face, he was said to have exclaimed something to the effect that, "Such things aren't supposed to happen to me!" Of course, since he had observed other aspects of "Cooper's Rules" by knowing his target and what was behind it, the primary damage was only embarrassment.
None of us are perfect, and all of us should constantly bear in mind the rules of gun safety when carrying and handling our firearms.
Thanks again for posting that article.
