Second Amendment commentary and case law are incorrect. But unfortunately, they are relied upon by today's scholars and jurists. However, this book, written in "plain English" instead of the legalese that many people find unappealing about books pertaining to legal subjects, takes the bold step of disproving these incorrect authorities on the most controversial and puzzling provision of the United States Constitution, and it meets that challenge. While other books on the Second Amendment rely largely on incorrect commentary and case law, this book uses credible and irrefutable documentary evidence to uncover the substance of the Second Amendment. By proving that Second Amendment commentary and case law are incorrect, this book will become both the preeminent treatise on the Second Amendment and a landmark book in the field of Constitutional law. And while gun control has been a highly controversial issue for a long time, the debate on gun control has been improperly bifurcated into what is good public policy and what is Constitutional. This book eliminates the Constitutional component of that debate so that it can be focused solely on what is good public policy. Other books written on the Second Amendment propose incorrect theories or attempt to reconcile its two supposed "clauses." However, this book is the best book ever written on the Second Amendment because it does what no other book has ever done. It uncovers, by means of documentary evidence instead of mere argument, the true meanings of the terms "A well regulated Militia," "the people," "keep," and "bear Arms." This book is current right up to the 2008 Supreme Court case of District of Columbia v. Heller, and the informationcontained in this book forms the foundation of what a correct determination of that case would be.
