Real Gun Gontrol is controlling your gun:
Walking properly with it--properly slung, properly shouldered, or carried in the ready position. Unless you are in combat, on patrol, or a Law Enforcement officer on a search, move with your weapon unloaded.
Walking properly in the rain--slung upside down so that the water does not get in the barrel.
Properly and safely crossing a fence row with your weapon--clear it, and carefully slide it under the fence, facing away from your line of walking, then cross to the opposite side as the trigger. Re-clear the weapon, insuring no obstructions.
Always be aware of where the barrel of your gun is pointing--it should never point at buildings or people.
Even if you just cleared your weapon, you always consider a weapon to be loaded.
And, of course, the most important element of gun control is to hit what you intend to hit, and effectively enough that a second shot is not required.
These are just some of the items that I learned at my daddy's knee.
I have a security system which involves a diverse arsenal deployed in a stratgic manner. Option 1, by the way is me holding a military weapon with a fixed bayonet. Since civilians are usually terrified of bayonets, I am sure that will do the trick.
