The Second Amendment to the US Constitution:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Lets look at this and discuss what the founding fathers had in mind when they wrote it.
A well regulated militia: Seems we are talking about a group of folks ORGANIZED into a fighting unit
being necessary to the security of a free state: Ahhh... it would appear the founders understood that govt, like any other humans, needed to have a force resisting unlimited power... to keep then in check.
The right of the people to keep and bear arms: The RIGHT of people to keep and bear arms... seems today we have folks literally SCREAMING they have a right to govt checks, healthcare, etc... looks to me like the founders decided firearms was/is a right also.
Shall not be infringed. STRONG language there... kinda like "What part of no do you not understand" or "Do not step across this line"
GA's comment: The second amendment, as most of the others, were written and are intended to be interpreted as the rule of law the citizens have the right to take to the govt and literally DEMAND the govt submit themselves to. Again, the founders understood the principles of unbridled power... and put in many a safeguard to give citizens the power to tell govt "NO you will not".
As discussed in different threads... The founders knew what was a lethal weapon and what was not... yet they still chose to not put any limitations on what was acceptable and what was not. Seems to me they were more interested in preserving freedom than arguing over gun types. Along this thinking... I see there is no restriction to owning a cannon... so again the founders were not interested in the tools... they were interested in preserving freedom from an oppressive govt.
