In 1914, the U.S. Supreme Court announced a strong version of the exclusionary rule, in the case of "Weeks v. United States", under the Fourth Amendment prohibiting unreasonable searches and seizures. This decision, however, created the rule only on the federal level. The ""Weeks" rule," which made an exception for cases at the state level, was adopted by numerous states at a time during prohibition. In adopting the rule, actions by states often reflected attitudes towards prohibition, which was enacted by adoption of the Eighteenth Amendment and was enforced through the Volstead Act. Concerns about privacy violations also extended to other instances where criminal sanctions were permitted for "victimless" crime, such as illegal gambling or narcotics violations.
