Does public attention on racial profiling impact police behaviour?

In "The Environmental Context of Racial Profiling", (2009), 623 ANNALS of the American Academy of Political and Social Science 52, Patricia Warren and Amy Farrell report their findings on the role of environmental factors like media scrutiny on reducing racial profiling. Based on their assessment of stop and search data from Rhode Island, the authors conclude that "[w]hen monitoring in the form of media attention is coupled with increased administrative accountability, the scrutiny that is generated apparently yields more equitable law enforcement."
