Fort Worth would achieve significant economic progress in the 1940s, especially from the addition of Convair, that would expand its population at a fast pace but would lose much of that momentum in the 1950s. During both decades the police confronted rising demands related to traffic control and internal corruption that most notably affected their ability to deal with gambling and prostitution, both of which seemed to be everywhere. As the 1950s drew to a close, both vices began to subside, more from a decline in public acceptance than from police activity.

In the 1940s and 1950s, Fort Worth's criminal underworld was a major presence, heavily involved in vice and in several daring robberies, including a thwarted plan to rob Carswell Air Force Base. The most notorious gangsters met their ends in a long-running series of internal conflicts that began during the war and destroyed most of that underworld. At the same time, the postwar period witnessed the spread of illegal drug use across broad societal lines, sparking a corresponding response by police. In contrast, little changed regarding race relations despite the efforts of many local activists and favorable rulings emanating from the nation's courts. More significant progress would come in the 1960s and accelerate thereafter.
