Oral history interview with Lloyd Bell (born 1925 in Los Angeles) conducted by Joseph Butner on September 18, 1973 for the Ralph Roske Oral History Project on Early Las Vegas. Lloyd discusses the challenges of policing Las Vegas, Nevada where the population includes both permanent residents and tourists, and he mentions the issue of drug and narcotics addiction in the city as it relates to crime. Lloyd then talks about the development and growth of Las Vegas, as well as the environmental and social changes in the city. The interview then shifts to a discussion on the significance of legal gambling in Las Vegas, which then moves to a related discussion on the existence of organized crime in Las Vegas.
