18 U.S.C. § 3113: Liquor violations in Indian country

If any superintendent of Indian affairs, or commanding officer of a military post, or special agent of the Office of Indian Affairs for the suppression of liquor traffic among Indians and in the Indian country and any authorized deputies under his supervision has probable cause to believe that any person is about to introduce or has introduced any spirituous liquor, beer, wine or other intoxicating liquors named in sections 1154 and 1156 of this title into the Indian country in violation of law, he may cause the places, conveyances, and packages of such person to be searched. If any such intoxicating liquor is found therein, the same, together with such conveyances and packages of such person, shall be seized and delivered to the proper officer, and shall be proceeded against by libel in the proper court, and forfeited, one-half to the informer and one-half to the use of the United States. If such person be a trader, his license shall be revoked and his bond put in suit. Any person in the service of the United States authorized by this section to make searches and seizures, or any Indian may take and destroy any ardent spirits or wine found in the Indian country, except such as are kept or used for scientific, sacramental, medicinal, or mechanical purposes or such as may be introduced therein by the Department of the Army.
