What is the 2nd amendment of the US constitution? Is it misunderstood?

Response:
The 2nd amendment of the US constitution relates to the right to bear arms.  The exact text, from the web, is "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."  This is a contentious law given that guns are a tool of violence.  And this amendment is touted by citizens of the US that want to buy and keep guns.  For me, the interesting part, often overlooked, is the preamble that a well regulated militia is necessary for the security of a free State.  This may have been relevant to all people in the 18th century.  Today, we already have that "militia".  All law officers and soldiers make up that militia.  The armed forces are well regulated and are tasked with protecting the nation.  We, the US, have the best military in the world.  So it is not necessary for any Tom, Dick, or Harry, without training or national perspective, to take up arms.  Especially when the process itself is getting more unregulated.  Gun control is necessary and not precluded by the 2nd amendment.  Safety of all citizens is indeed mandated by the constitution.
