When Daunte Wright was killed last spring by a police officer in Minnesota after being pulled over for expired registration tags, the case drew national attention. So have several other seemingly avoidable deaths of motorists. Now, a New York Times investigation reveals the scope of such cases across the country and why traffic stops for minor offenses can escalate into fatal encounters. Over the last five years, The Times found, the police killed more than 400 drivers or passengers who were not wielding a gun or a knife or under pursuit for a violent crime. Traffic stops " which are often motivated by hidden budgetary considerations because of the ticket revenue they generate " are the most common interactions between police officers and the public. Yet the police consider them among the most dangerous things they do. Presumption of peril has been significantly overstated, but it has become ingrained in police culture and court precedents " contributing to impunity for most officers who use lethal force at vehicle stops. In case after case, officers avoided criminal liability when they claimed to have acted in self-defense. In the roughly 400 deaths, five officers were convicted. Nearly two dozen cases are still pending. While prosecutors deemed most of the killings justifiable, local governments paid at least $125 million to resolve legal claims in about 40 cases.
