Amadi v. United States

stating that due process may be denied when a sentence is enhanced after the defendant has served so much of his sentence that his expectations as to its finality have crystallized and it would be fundamentally unfair to defeat them | analyzing the admissibility of a police officer’s tape-recorded observations alternatively as present sense impressions and prior consistent statements | compelling prejudice does not exist automatically where one defendant asserts an entrapment defense at a joint trial | stating, “determination of whether dismissal shall be with or without prejudice is left to the sound discretion of the trial judge” | conspiracy and possession with respect to four ounces of cocaine held to be “undeniably serious” under Section 3162(a)(2) | after a dismissal under the STA. "Nevertheless the judge has discretion to decide whether the prosecution will be barred” | joinder proper where offenses were part of “series of transactions” which were facially similar, and there was substantial overlap of participants who shared same objective and displayed common mode of operation | offenses involving four ounces of cocaine “undeniably serious” | dismissal without prejudice involving a violation of 35 days | shifting burden of proof for entrapment defense
