Congress defined the meaning of a militia by an act of Congress in 1790. In the language of the time it included all free trustworthy males between the ages of 16 and 60. Some would say that this would allow the government to prohibit males over the age of 60 from owning weapons. However, in other legislation from the period a trend appears in the use of clauses: The first clause gives the rationale for the active second clause. To update the meaning of militia, it would be everyone above the age of 16 who does not have a felony. "The right of the people" is considered to mean individual rights in every other instance in the Constitution. It is only in the Second Amendment that people begin to waffle. This is an identifying mark. It reveals the person who is frightened by the free individual...the person who is an enemy of liberty and an ally of statists of every stripe.
But folks, the Bill of Rights is NOT a grant from a beneficent government...it is an enumeration of rights that exist in and of themselves. It is a reminder to the government. In actuality, my right to own weapons comes from my rights to life and liberty. Weapons are tools to defend my life and my liberty. The right of self defense is a fundamental human right. The Second Amendment is not about hunting, "sporting purposes", or even defense from criminals. It is about maintaining the people's ability to resist tyranny. And that is what frightens the statists for they know in their hearts that they are striving to be tyrants.
Nuclear weapons? Well, aside from the cost as DC mentioned and the utter idiotic absurdity of the people who use this argument... How am I going to use it to defend myself? Or my family? A rule of thumb I use is this: Would you trust the guys at the shooting club with it? The nut across the street? If you wouldn't you had damn sure better not trust a government with it. If you look at the body count from governments versus murders by private individuals, maybe we should disarm the governments. 60 million dead in seven government sponsored genocides preceded by gun control laws in this century. 60 million dead from the statists in Soviet Russia, 30 million dead in China, 2 million dead in Cambodia. We haven't even counted the war dead yet or the "collateral dead."
No matter what the weapon, some individual controls it. Are you happy with the individual who controls US's nuclear arsenal tonight?
A word of warning about a chink in our defenses: Felonies. Compare how many actions are felonies today that were not in 1900. And yet we made it through the preceding 124 years without the world ending.
This should be restricted to violent felonies and then fine tuned. I don't know if you all have noticed but the laws of self defense have been progressively narrowed in interpretation if not in the letter of the law. This should be broadened. On the other other hand what constitutes assault should be restricted.
To give an example, a friend of mine named Dennis Sapp was accosted on his property by two armed teenagers. Armed with a Ruger Redhawk .44 Mag and a .357. They tried to get out of their truck with revolvers in hand. They didn't make it. Dennis outnumbered them. They received skull fractures, tympanic membrane ruptures, assorted lacerations, contusions, abrasions and fractures. Dennis was charged with kidnapping (because he continued whipping their butts after they decided they really, really wanted to leave) and aggravated assault (because he continued stomping them after they could no longer murder him.) The prosecutor dropped the kidnapping charge and Dennis was convicted on the assault charge. The teenagers were not charged. So, Dennis can never own a firearm, right? This is justice?
