Gros Ventre Tribe of the Fort Belknap Indian Reservation v. United States

How later courts describe this case

• recognizing the government's "special interest in securing the presence of the accused at trial"
• consent not involuntary where officer asserted that if defendant did not consent to the search of his luggage he would seek a warrant
• warrantless entry and reentry of a boat where drowning suspected and tidal flow created need for swift action
• justified where "[t]here were no `No Trespassing' signs or fences restricting access to the property"
• no rea sonable expectation of privacy because boat, like automobile, carries lesser expectation of privacy than home or office
• statement that a search warrant will be obtained does not in itself render the consent involuntary
• in context of all the criteria of voluntariness set forth in Schneckloth, federal agent’s assertion that he would seek a warrant if appellant did not consent did not alone render consent involuntary
• a mixed motive for a stop is irrelevant once finding of probable cause is made
