PG&E formally asked a federal judge on Monday to dismiss eight criminal charges against it for causing a fatal explosion in San Bruno, but government prosecutors countered during a court hearing they will prove that the embattled utility deliberately broke an array of laws in the case. After a court hearing in San Francisco, San Bruno City Manager Connie Jackson said she's confident the government will prove its criminal case against PG&E and that she was dismayed by the utility's efforts to get all charges tossed out in the case.
