Where does it end guys? As far as the level of destruction an individual should be entrusted with? An Abrams tank? A fully armed F-15? An Aricraft Carrier if one could afford it? His own personal Nuclear Warhead? As much as I'm in agreement about an individual owning ANY military PERSONAL firearm, I think common sense would dictate a limit on what any one person should be able to unleash.
MY Definition of PERSONAL firearm (Maybe not yours): ANY weapon an individual can personally carry and fire himself. With the possible execption of certain fully automatic machine guns (i.e. twin .50 cal. or maybe a Mini-Gun)which would need to be mounted on something stable to fire properly. Such machine guns should be allowed if the individual can prove training in the proper use and care of such a weapon has been completed.
BUT, common sense should be used and the practiclity of such a weapon should be considered before purchasing one. Example: A rancher in Arizona or one of the other border states should be able to own and defend his or her ranch with the use of such a weapon if trained to use it. However, someone living in say St. Louis should use restraint in mounting one of these weapons on his truck and running around town with it. That's just one example I'm sure there are many other examples that could be stated here and I'm sure will be.
In other words we should use common sense when selecting what weapon we need to use to defend ourselves from a given threat. Weapons of Mass Destruction should IMO not be in the hands of ANY individual period. People snap and kill several people before being stopped. Should we all be restricted from owning a personal defense weapon, or even a military firearm? Absolutely not!!! But should we be able to take out an entire city if one of us snaps? Absolutley NOT!!!
I don't think you are getting the point. The Founders didn't address the type of weaponry that could be owned for a reason! I see many believe that the Founders "couldn't have envisioned the kinds of arms that would arise", and therefore, we need restrictions on what people can and cannot own. In reality, the lack of addressing what kind of firearms could and couldn't be owned was a future-proof stroke of genius!
I believe the Founders understood that technology would advance in weaponry, they had already seen it during their lifetime. The fact is that they didn't specify, because they believed firearms were a source of protection of one's self AND protection from oppression. It wasn't an issue of whether or not you should be allowed to own a machine gun, it was an issue of whether or not you were allowed to own the kinds of weaponry that would give you a fighting chance against the aforementioned threats. If a criminal attacks you with a knife, should you be allowed only to use a knife for defense? If an army advances on you with RPG's, should a hunting rifle be all you are allowed to fight them off with? You see, the Founders didn't restrict it so that you would have the right to wield whatever was necessary.
Notice, they didn't mandate that everyone own a firearm! They didn't require that your firearm be military grade, either! They founded a free market society. Landowners had better muskets than the poor. WMD's like canons were owned only by the wealthy. This wasn't thought of as unfair, but merely as a sense of balance. Moving forward to today, not everyone can afford the latest military arms, but does that mean they shouldn't be allowed to have them if they can? If the unthinkable ever happened and America was threatened on its own soil, would you be grateful if someone in your community actually had some heavier weaponry to help make a stand, even though all you could afford was an AR or AK?
You see, the problem isn't that weapons have improved over time, the problem is that Americans have grown too smug in their belief that they are untouchable. Ask anyone being oppressed in a war torn country if they wished they had better arms to rise up and match those of their oppressors and I guarantee they would answer in the affirmative. If a foreign nation ever were to invade this one, I would hope that we had not legislated ourselves out of the ability to defend ourselves by whatever arms possible! I think the Founders thought the same way.
