What are the motifs in Unintended Consequences by John Ross?

The 2nd amendment is a recurring idea in the book. "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." So reads the 2nd Amendment to the U.S. Constitution, and it is the primary basis upon which author John Ross presents his argument against federal and state restrictions upon gun ownership.
