Brody v. Guercio

indicating that in certain circumstances the privilege may be extended to state legislators | “[A]n informant who is promised a contingent fee by the government is not disqualified from testifying in a federal criminal trial.” | “[t]he courts have long recognized that the definition of an informer includes persons who provide evidence against a defendant for some personal advantage or vindication, as well as for pay or immunity” | in order to obtain a conviction for perjury, the Government must prove that the statements made by the defendant were (1) false, (2) material, and (3) not believed by the defendant to be true | “[T]he trial court must give the jury careful instructions pointing out the suspect credibility of a fact witness who has been or expects to be compensated for his testimony.” | “[n]o practice is more ingrained in our criminal justice system than the practice of the government calling a witness who is an accessory to the crime for which the defendant is charged and having that witness testify under a plea bargain that promises him a reduced sentence.” | “No practice is more ingrained in our criminal justice system than the practice of the government calling a witness who is an accessory to the crime for which the defendant is charged and having that witness testify under a plea bargain that promises him a reduced sentence.”
