United States v. Posada-Carriles, 541 F.3d 344 (5th Cir. Aug. 14, 2008) (government's naturalization interview of defendant was not a mere pretext for a criminal investigation, and the government's conduct was therefore not so deceptive and outrageous that it merited dismissal of the indictment, even though interviewer knew noncitizen was not likely eligible for naturalization due to prior criminal activities, and had alerted DHS prior to interview).
