What do you think?

We know that the Sixth Amendment right to confront witnesses does not apply at a sentencing hearing (although the Due Process Clause does).  Here we have a report of United States v. Carrillo, 2018 U.S. Dist. LEXIS 21731 (E.D. N.Y. Feb. 9, 2018), in which the judge held that the exclusionary rule does not apply at sentencing.  The district court judge cited to United States v. Tejada, 956 F.2d 1256, 1263 (2d Cir. 1992).
