The original constitution of USA had seven articles and did not have the right to bear arms. Amendments to the constitution added more articles. The Congress on 25 September 1789 proposed to add 12 articles as amendments. Of these first 10 were ratified and came into effect on 15 December 1791.
Second amendment: 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.
The above amendment has been used by vested interests who are merchants of death to sell arms and ammunition without restriction and without regard to loss of innocent lives. National Rifle Association opposes restrictions on the sale of arms.
Some debate the meaning and purpose of second amendment; whether the right is to an individual or to people as a whole and whether arms can be obtained to kill others. USA in 1789 was not a superpower. It did not have a large army, navy and air force. At that time it may have been necessary to allow people to keep arms to enlist them in the army to fight wars.
The shooting in a theatre in Aurora, near Denver in Colorado, is the latest example of a list of shootings in which murderers used weapons of mass destruction. Then there are examples of murderers who have used guns to kill specific individuals.
People who have lost their near and dear ones in shootings shall try for repeal of second amendment. Shops that sell guns, rifles, pistols, revolvers, bullets and such things shall shut down. Laws requiring background checks and waiting periods have failed to stop murderers from purchasing guns. People who have arms should be asked to register themselves and their arms and ammunitions.
