A report said Friday the Texas Department of Public Safety is in need of a major overhaul. The study of DPS by a consulting company identified significant problems in the department. The study was compiled after an arsonist nearly destroyed the Governor's Mansion in June. It was later revealed that there were too few guards and malfunctioning security equipment at the site. The report calls for combining all DPS law enforcement divisions under a single deputy director and deploying them across the state through a new regional command structure.
