The attorney general's office - and every prosecutor - should be barred from making any public comment on a pending case short of an initial announcement at the time charges are filed.
A statement at that time should follow a predetermined script and cite the applicable sections of the law. Any further comments to the media by the prosecutor and any leaks from the prosecutor's office should be grounds for stiff penalty and a the immediate dismissal of all charges.
There is no reason other than grandstanding for the prosecutor to be issuing public comments. The place for the prosecutor to make their case is in the courtroom.
