Does The Second Amendment Protect Firearms Commerce?, David B. Kopel

David B Kopel

The Second Amendment protects the operation of businesses which provide Second Amendment services, including gun stores. Although lower federal courts have split on the issue, the right of firearms commerce is demonstrated by the original history of the Second Amendment, confirmed by the Supreme Court in District of Columbia v. Heller, and consistent with the Court's precedents on other individual rights.

The History Of Firearm Magazines And Magazine Prohibitions, David B. Kopel

David B Kopel

In recent years, the prohibition of firearms magazines has become an important topic of law and policy debate. This Article details the history of magazines and of magazine prohibition.

Because ten rounds is an oft-proposed figure for magazine bans, Part I of the Article provides the story of such magazines from the earliest sixteenth century onward. Although some people think that multi-shot guns did not appear until Samuel Colt invented the revolver in the 1830s, multi-shot guns predate Col. Colt by over two centuries.

Especially because the Supreme Court’s decision in District of Columbia v. Heller considers whether arms are …

David B Kopel

Posse comitatus is the legal power of sheriffs and other officials to summon armed citizens to aid in keeping the peace. The posse comitatus can be traced back as least as far as the reign of Alfred the Great in ninth century England. The institution thrives today in the United States; a study of Colorado finds many county sheriffs have active posses. Like the law of the posse comitatus, the law of the office of sheriff has been remarkably stable for over a millennium. This Article presents the history and law of the posse comitatus and the office of sheriff …

David B Kopel

This Article analyzes the changes in orthodox Christian attitudes towards defensive violence.

Knives And The Second Amendment, David B. Kopel, Claytom E. Cramer, Joseph P. Olson

David B Kopel

This Article is the first scholarly analysis of knives and the Second Amendment. Under the Supreme Court’s standard in District of Columbia v. Heller, knives are Second Amendment “arms” because they are “typically possessed by law-abiding citizens for lawful purposes,” including self-defense.

There is no knife that is more dangerous than a modern handgun; to the contrary, knives are much less dangerous. Therefore, restrictions on carrying handguns set the upper limit for restrictions on carrying knives.

Prohibitions on carrying knives in general, or of particular knives, are unconstitutional. For example, bans of knives that open in a convenient way (e.g., …

Sex, Drugs, Alcohol, Gambling, And Guns: The Synergistic Constitutional Effects, David B. Kopel, Trevor Burrus

David B Kopel

In this Article, we discuss the synergistic relationship between the wars‖ on drugs, guns, alcohol, sex, and gambling, and how that relationship has helped illegitimately increase the power of the federal government over the past century. The Constitution never granted Congress the general police power‖ to legislate on health, safety, welfare, and morals; the police power was reserved to the States. Yet over the last century, federal laws against guns, alcohol, gambling, and some types of sex have encroached on the police powers traditionally reserved to the states.

Congress‘s infringement of the States‘ powers over the health, safety, welfare, and …

The Great Gun Control War Of The Twentieth Century--And Its Lessons For Gun Laws Today, David B. Kopel

David B Kopel

A movement to ban handguns began in the 1920s in the Northeast, led by the conservative business establishment. In response, the National Rifle Association began to get involved in politics, and was able to defeat handgun prohibition. Gun control and gun rights became the subjects of intense political, social, and cultural battles for much of the rest of the 20th century, and into the 21st.

Often, the battles were a clash of absolutes: One side contended that there was absolutely no right to arms, that defensive gun ownership must be prohibited, and that gun ownership for sporting purposes could be, …
