The past two decades have witnessed Macao's development into the casino capital of the world. Casinos have significantly transformed all respects of Macao society - a phenomenon termed as the casinoization of Macao. While much research has explored how casinoization has affected Macao's socioeconomic developments, empirical research on the relationship between casinoization and law enforcement agencies is extremely limited. Using official statistics and interviews with serving and retired police officers as well as police applicants in Macao, this article examines the quick-money mentality, laissez-faire regulation, and the paradox of plenty, three features of casinoization, and their profound impact on the Macao police. First, the early phase of casino liberalization created a draining effect on human capital from the police force. Second, the lucrative casino tax revenues empowered the government to resolve the labour shortage issue and significantly improve the police image. Third, casinoization inadvertently reinforced the colonial legacy of laissez-faire regulation, hampering the progress of institutional reforms. Fourth, the decline of casino has contributed to the unprecedented "police fever"among the youth in Macao.
