While some public agencies in San Diego County delay or outright fail to turn over public documents, a San Diego Union-Tribune review found they’re far more responsive than federal agencies, which have more freedom to delay or under weaker public records laws. In January U-T Watchdog sought six months’ worth of email records that contained four phrases — “off the record,” “off record,” “on background” and “deep background” — from nearly 100 public agencies. The phrases refer to reporters’ and sources’ agreements to confidentially share information.
