Self-defence is a basic human right, both for individuals and for nations - or for animals, for that matter. It is the most basic right of living creatures. An unprotected home is not a safe and secure home, and a handy gun is as essential as a shovel, duct tape, or a pair of pliers.
You cannot defend yourself and your family with a whistle and a phone call to 911 any more than Israel can defend herself with a phone call to the UN.
Guns are the best tools for self-defence by far, plus they are fun, too. And, thank God, we are still allowed to shoot when bad guys invade our space and our lives.
Looked at one of these yesterday at the gun shop. The Marines use them. I like it. Bad guys hate it, because it can turn their heads into instant pizza-topping, which is highly discouraging to those with evil intentions. The Benelli M4. One ugly-looking shotgun.
