The orginal purpose of the 2nd Amendment has been given a distorted interpretation by the gun lobby.
The original intent was that the states, when they joined the federal union, could keep their state militia. The gun lobby has turned that restricted interpretation into an unrestricted right for any and everyone to own any number of high-powered firearms.
The gun industry is a multi -billion $$$ business. Their profits are at the center of the gun issue. Their lobbyists fight any gun control legislaion from congress. As a result the U.S. has millions of guns in circulation. Every year in the U.S. thousands of people are killed and wounded by guns.
