by denying the admission at trial of affidavits Zahn contends supported his case. See Fed.R.Evid. 801(c) and 804(a); cf. Mutuelles Untes v. Kroll & Linstrom, 957 F.2d 707, 713 (9th Cir.1992) (explaining that, to be admissible under Fed. R.Evid. 804, affidavits require more than an oath alone to guarantee the trustworthiness of the affiant). The district court also did not abuse its discretion by admitting letters from Zahn’s physician and psychologist. See Chuyon Yon Hong v. Mukasey, 518 F.3d 1030, 1034 (9th Cir.2008) (explaining that the exclusionary rule “is an exceptional remedy typically reserved for violations of constitutional rights” in criminal cases) (citations and internal quotation marks omitted); cf. Haddad v. Lockheed Cal. Corp., 720 F.2d 1454, 1456 (9th Cir.1983) (<HOLDING>). We decline to consider Zahn’s contentions
