More on gov's mansion

Texas Department of Public Safety officials talked about their investigation into the blaze at the Texas governor's mansion yesterday and said: Only 13 of 20 security cameras were working; although two troopers were requested to be on duty, only one had been assigned; the trooper on duty was not adequately trained to monitor the security system. He happened to be looking away from the monitor, using a computer, when the arsonist torched the mansion.
