Pinto-Montoya v. Mukasey, 540 F.3d 126 (2d Cir. Aug. 26, 2008) ("We conclude that petitioners' contact with immigration officials at the airport was not a seizure
within the meaning of the Fourth Amendment because no force, threat of force, or other assertion of authority was used by the officials. Because petitioners were not seized, the statements obtained from petitioners by the immigration officials were properly admitted.").
