On Treason : A Citizen's Guide to the Law

A concise, accessible, and engaging
guide to the crime of treason,
written by the nation’s foremost
expert on the subject

Treason—the only crime specifically defined in
the United States Constitution—is routinely
described by judges as more heinous than
murder. Today, the term is regularly tossed around by
politicians and pundits on both sides of the aisle. But,
as accusations of treason flood the news cycle, it is not
always clear what the crime truly is, or when it should
be prosecuted. 

Carlton F. W. Larson, a scholar of constitutional
law and legal history, takes us on a journey to understand
the many subtleties of the Constitution’s definition of
treason. With examples ranging from the medieval
English Parliament to the accusations against Edward
Snowden and Donald Trump, Larson brings to life
not only the most notorious accused traitors, such as
Benedict Arnold, Aaron Burr, and World War II’s
“Tokyo Rose,” but also lesser-known figures, such as
Hipolito Salazar, the only person ever executed by the
federal government for treason, and Walter Allen, a
labor union leader convicted of treason against the
state of West Virginia in the early 1920s. 

Grounded in over two decades of research, On
Treason is an indispensable guide for anyone who wants
to understand the role of treason law in our constitutional democracy. With this brisk, clear look at the
law’s history and meaning, Larson explains who is actually guilty and when—and readers won’t need a law
degree to understand why.
