This training film from the Texas Ranger Hall of Fame and Museum was made by the Texas DPS to educate law enforcement agents on various methods of safe burglary and techniques for gathering evidence during an investigation. The film demonstrates using explosives, hammers, and other tools to break into safes, followed by forensic procedures to gather fingerprints and distinct tool markings used as evidence to present to a jury during prosecution.
Established by the Texas Legislature on August 10, 1935, the Texas Department of Public Safety was created by the consolidation of the Texas Highway Motor Patrol with the Texas Rangers. Since that time, its duties have grown to include such activities as the state licensing of drivers, vehicle inspection, narcotics enforcement, and the State Civil Defense Office, (now the Division of Emergency Management,) which aids local governments during times of natural disaster or social upheaval. While its duties have evolved over time, the mission of the DPS has remained constant - to provide public safety services to those people in the state of Texas by enforcing laws, administering regulatory programs, managing records, educating the public, and managing emergencies, both directly and through interaction with other agencies.
Colonel Homer Garrison Jr.'s lifelong Texas law enforcement career began at age 19 (shortly after graduating from Lufkin High School), when he was appointed deputy sheriff of Angelina County. In 1930, he joined the newly forming Texas Highway Patrol. When the Texas Highway Patrol became part of the Texas Department of Public Safety in 1935, Col. Garrison became the new agency's first assistant director. In 1938, his role changed to director of the DPS and chief of the Texas Rangers, a position he held until his death in 1968. The Texas Ranger Hall of Fame and Museum at Fort Fisher is named for him.
