Why is the prosecutor asking the victim for a sworn statement?
Prior testimony under oath is admissible when an alleged victim later becomes unavailable due to assertion of a testimonial privilege. A prosecutor who is concerned that a witness may become uncooperative may consider using a court reporter to make a record of any testimony during the early stages of the prosecution, such as bond hearings or preliminary hearings. A prosecutor can then refer back to the prior testimony to keep the testimony consistent.
