I must chime in as the contrarian here.
First, I'm not sure from where Michael Stones hails, but since the US Constitution (including the Bill of Rights) was adopted more than 30yrs before the War of 1812 it should be obvious that the 2nd Amendment was not a reaction to that war. The 2nd Amendment was explicitly included because the colonies had just fought a war against a tyrannical government which could not have been won without the ownership of and willingness to use firearms by the populace. It doesn't protect one's right to a shotgun for bird hunting. It protects us from tyranny. It does not give us the right of self defense, it merely protects that right.
Since many of OPF's readers and contributors are not from the US and obviously many who live here are unfamiliar with the process, allow me to describe the legal purchase of a new firearm in New Mexico. Bear in mind that NM is very liberal in our firearms laws. No registration requirements, licenses, and such. This procedure differs slightly for concealed carry weapon permit holders, but only in the background check.
First, one must pay a visit to a licensed dealer, one who holds a Federal Firearms License (FFL). You fill out a silly yellow form, which must be retained indefinitely by the dealer under penalty of law, in which you affirm that you are legally allowed to buy a firearm. In other words, you're not a convicted felon, haven't been convicted of even misdemeanor domestic violence, aren't a drug user, and so on. You must be buying the gun for yourself as well (so called straw purchases are illegal). Then you have to sign that form, which theoretically can mean serious penalties if you lie. That got the idiots who bought the guns for the Columbine kids in some serious hot water. The form includes lots of gory details about you, full name, date of birth, drivers license number, Social Security number (optional), and so on.
The date of birth is important. You must be 21 to buy a handgun, 18 for a long gun.
Now the dealer will phone up the state police for a mandatory background check. This is the bit that isn't required if you hold a CCW permit. They have 3 options: yes, no, or maybe. Yes, you walk out with your purchase. No, something came up and you will have to appeal directly to the state police if you believe there was an error. Theoretically you could be arrested at this point for providing false information, but that is unfortunately almost unheard of. Maybe means they need to dig a little and have 3 days in which to deny the sale or it can proceed.
This is absolutely not the case in many US jurisdictions. For example, in Washington, DC it's not even legal to buy, sell, or possess (in most cases) a handgun. Other locales require mandatory waiting periods. Some limit purchases to one per month. Basically the gamut runs from the minimum required by federal law (such as NM) to you can't buy a gun legally no matter what you do.
How difficult do you suppose it is to get a gun illegally? I don't have any first hand experience, but evidence suggests it's very easy. Want to stay legal? Jump through hoops. Don't care? Cash is all you need. The criminals already don't care, so why would we expect another law to make a difference?
I personally believe there's a strong correlation between the fact that Washington, DC has such strict rules to the fact that they bounce in and out of the lead for US murders. It's even illegal to have a gun in your home for self defense in DC. Of course these rules aren't really applied to the ruling class, so they don't have to be bothered.
There's a lady in Texas who is now a legislator who's parents were murdered in a mass shooting at a restaurant several years ago. She had a gun in her car, but obeyed the law that said she couldn't bring it in the restaurant (a McDonald's if I recall correctly). The body count was considerable and the guy was only stopped when the police killed him. Do you believe they'll be there to protect you or do you believe it's both your right and responsibility to protect yourself and your family?
Tell me all about the civilized world.
