So what happens when the sole arbiter of what a witness says in an FBI interview is the 302 Report written by an FBI agent? If that witness should later be compelled to testify at a grand jury proceeding (leading to an indictment of the target of the investigation) or at the trial itself, he is under tremendous pressure to testify consistently with what the 302 report claims he told the agents when interviewed. Should a witness give testimony that is in conflict with the 302 report, he opens himself up to a felony conviction –either he had lied to the FBI in his initial interview, or he is lying to the grand jury or the court (or the congressional committee) in his testimony. Either way, he remains stuck between the Scylla of perjury and the Charybdis of a false-statements charge. Few question the veracity of the 302 report; after all, who will a jury more likely believe, a single witness or two upstanding FBI agents swearing that what they wrote in their 302 report accurately represents what the witness said when interviewed?
Why would the government do this?
