A hidden scaffolding of financial incentives underpins the policing of motorists in the United States, encouraging some communities to essentially repurpose armed officers as revenue agents searching for infractions largely unrelated to public safety. As a result, driving is one of the most common daily routines during which people have been shot, Tased, beaten or arrested after minor offenses.
Some of those encounters — like those with Sandra Bland, Walter Scott and Philando Castile — are now notorious and contributed to a national upheaval over race and policing. The New York Times has identified more than 400 others from the past five years in which officers killed unarmed civilians who had not been under pursuit for violent crimes.
Fueling the culture of traffic stops is the federal government, which issues over $600 million a year in highway safety grants that subsidize ticket writing. Although federal officials say they do not impose quotas, at least 20 states have evaluated police performance on the number of traffic stops per hour, which critics say contributes to overpolicing and erosion of public trust, particularly among members of certain racial groups.
Many municipalities across the country rely heavily on ticket revenue and court fees to pay for government services, and some maintain outsize police departments to help generate that money, according to a review of hundreds of municipal audit reports, town budgets, court files and state highway records.
