Second Amendment [PDF ebook] 

The United States has the most guns per capita of any country in the world. Many Americans value the right to bear arms, which they believe is guaranteed by the Second Amendment to the Constitution. Others believe that the Second Amendment only guarantees the right for organized militias to own guns. This book surveys the history of the Second Amendment and gun ownership in the United States, and explores how the amendment continues to affect us today.
