What is a Dallas County Sheriff’s Reserve Deputy?

A reserve deputy is a person from the community who volunteers his or her time as a uniformed deputy sheriff. They have been fully trained through a TCOLE-approved Police Academy as a peace officer and have full arrest authority under Texas State law. Reserve deputies are held to the same high standards as regular full-time deputies. Therefore, each reserve deputy must pass an extensive background investigation plus meet all medical and psychological criteria.

Reserve deputies serve at the will of the sheriff and are used to support and supplement the deputy workforce. Duties include and are not limited to:

DWI patrol

Fugitive Transfer

Jail Support

Warrant Execution

Drug Interdiction

Brief History of the Dallas County Sheriff’s Reserve:

The Dallas County Sheriff’s Reserve was started in June 1951 from an idea at a meeting between Sheriff Bill Decker and Col. Harold B. Younger of the Texas State Defense Guard. The guard had been put on inactive reserve status upon the return of the National Guard units after World War II. Many of these state guardsmen felt that they did not want their training to go to waste as they still wanted to be of service to their country in case of an emergency.

From that June meeting, Class I was created. On July 24, 1951, a total of 59 guardsmen began their training.

Reporting for training once a week for two hours, the class met in the old Criminal District Court # 2 of Judge Robert A. Hall. The reservists were directed during their training by Sheriff Bill Decker and Deputy Charles Polk Player.

Class I held their graduation in the same courtroom where they had received their training on December 11, 1951.

The Dallas County Sheriff’s Reserve has been called to duty many times in its 73-year history. What started out as reserve officers supplementing the patrol section grew to cover all areas of the sheriff’s department. (Patrol, Warrants, Fugitive, and Detention Services) In addition to the everyday functions of the department, the Reserve Division has been mobilized for major events and disasters throughout Dallas County.

Volunteer Horseman.

The Dallas Sheriff’s Posse is a volunteer group of reserves that is also made up of horsemen. Their primary responsibility is enhancing the image of the department through community involvement.

The posse is utilized in many different functions, including search and rescue, escort service for dignitaries, public relations, and security at special events in or outside of Dallas County, all under the direction of the Dallas County Sheriff.

Mounted Patrol

The Dallas Sheriff’s Posse Mounted Patrol is a volunteer group of reserves who are also horsemen. The Mounted Patrol operates with legal authority in and outside of Dallas County under the orders of Dallas County Sheriff Marian Brown, helping maintain law and order. In addition to representing the department through community involvement, the Posse’s special and unique skills are called upon and utilized for some very specific and specialized functions.

Crowd Control & Event Security

The presence of a uniformed, armed officer on horseback is exceptionally effective in controlling large crowds and providing security at large-scale events. One Sheriff’s Posse officer on horseback can accomplish the same effect as several officers on foot or in a squad car. Police departments have described the Posse as “indispensable” and as “having prevented disasters and riots” at sporting events, concerts, circuses and outdoor festivals.

Missing Person Searches

When a child, elderly person or other individuals are reported lost, the Posse forms Search & Rescue teams on horseback and foot — far more effective than cars at locating the missing person.

Security Escort for Presidents and Dignitaries

The Dallas Sheriff’s Posse was the first in Texas and one of very few in the nation to receive certification to work with the Secret Service and has provided security escorts for Presidents Ronald Reagan, George H. W. Bush, George W. Bush and President Barack Obama.
