Economist Jennifer Doleac of Texas A&M University talks with EconTalk host Russ Roberts about her research on crime, police, and the unexpected consequences of the criminal justice system. Topics discussed include legislation banning asking job applicants if they've been in prison, body cameras for police, the use of DNA databases, the use of Naloxone to prevent death from opioid overdose, and the challenges of being an economist who thinks about crime using the economist's toolkit.
