The Espionage Act of 1917

The Espionage Act of 1917 is a U.S. law that was enacted during World War I to prevent spying and the sharing of sensitive government information. It makes it illegal to interfere with military operations, enlistment, or to disclose classified details that could harm national security. The law also aimed to control dissent against the war, leading to restrictions on free speech. Penalties for violating the law can include fines and imprisonment. Over the years, it has been invoked in various cases concerning national security and has implications for civil liberties, especially regarding freedom of expression.
