These four words, "shall not be infringed" is an absurdity.
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.
Arms are nunchucks, gravity knives, fragmentation grenades, anti tank bazookas, claymore mines, fully automatic long guns, surface to air missiles, etc. etc. Thus the logic is clear, "shall not be infringed" is negotiable on all lethal weapons. That includes small arms too!
Now, control does not take away all firearms in the control of millions of us. Gun Control is common sense: Do to the number of murders; The number of mass killings of innocents people going on way on days when they are in the wrong place at the wrong time, such as schools, movie theaters, concerts, parks, restaurants, and driving home on highways; Suicides and Accidents.
The costs of these four words, "shall not be infringed" is not only an absurdity, it costs the nation an enormous amount of treasure and blood.
