Creates provisions relating to informants in criminal proceedings

HB 2658 establishes a new system for tracking and disclosing information about informants in Missouri criminal cases. It requires prosecutors to maintain a confidential record detailing the testimony, benefits offered, and criminal history of any witness who testifies in exchange for leniency. The bill mandates that this information be shared with defense attorneys and used during pretrial hearings to determine if the informant's testimony is reliable enough for trial. Additionally, if the testimony is admitted, judges must instruct juries to consider the disclosed details when evaluating the witness's credibility.
