The Tennessee Dept. of Safety and Homeland Security is always on alert, and for a good reason. The department has the primary responsibility and authority for directing statewide activities to prevent terrorism in Tennessee. The department is made up of Drivers Services, The TN Highway Patrol, The TN Highway Safety Office, as well as Homeland Security. Tennessee Matters host John Clark recently talked with Safety and Homeland Security Commissioner Jeff Long and TN Highway Safety Office Director Buddy Lewis about the state of safety and security in Tennessee, and what you can do to help.
