First off, thank you for fixing my link.
The issue of gun ownership, gun safety, societal safety and the obligation we have to each other in society comes down to this. It is sad that so many think they need a personal weapon to protect themselves from perceived danger in our society. Weather or not you believe this perception is correct, it does not seem necessary (to me) to own weapons that can kill dozens and dozens of people in under a minute. That does not seem like self protection. That seems, to me, like something very dangerous and very unnecessary.
