ST. LOUIS o Circuit Lawyer Jennifer Joyce says she’s protecting criminal offense victims and witnesses from possible harm by withholding their details from defense attorneys.Her district attorneys have, for a minimum of a decade, stripped out dates of birth, Social Security numbers, phone number and addresses from police reports before providing them to defense attorneys.But Mary Fox, head public defender in St. Louis, states that enduring practice breaches Missouri Supreme Court rules and deprives offenders of their constitutional right to a fair trial.
