Among many other things, Proposition 115 added section 30, subdivision (b) to article 1 of the California Constitution, declaring hearsay evidence is admissible at preliminary hearings in criminal cases "[i]n order to protect victims and witnesses . . . ." The measure also amended "section 872, subdivision (b), of the Penal Code to provide that a probable cause determination at a preliminary hearing may be based on hearsay statements related by a police officer with certain qualifications and experience."
