Hiding behind the 2nd Amendment is absurd. The writers of the Constitution did not intend or foresee the sad state of gun ownership that exists today.
The origins lie in militias, not in every citizen being armed to the teeth with automatic weapons.  Gun lobbyists have taken the constitution and twisted it to serve their own distorted views.
"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."
