Blue City Crime: What Both Sides Get Wrong According to Criminologist David Kennedy

Like almost everything else in present day America, crime in blue cities has become a deeply partisan and polarized issue. While progressives routinely downplay levels of urban crime and call for a singular focus on “root causes” like poverty and racism, Trump, with the enthusiastic backing of the MAGA law-and-order right, grossly exaggerates the dangers of blue cities. He has ludicrously referred to such cities as “war zone(s)” and "hellhole(s)" as, in a dangerously authoritarian escalation, he’s deployed the National Guard to Washington, D.C., Chicago, and more recently Portland. 

So, what’s true and what’s not about crime in blue cites? And what works and what doesn’t in fighting it?

For answers, we turn to one of the country’s most prominent and respected criminologists. David Kennedy is a long-time professor of criminal justice at John Jay College of Criminal Justice in New York City, and the director of the National Network for Safe Communities. Several decades ago, Kennedy famously drew upon insights into urban crime spikes associated with the crack epidemic to devise innovative intervention strategies to interrupt the surging violence that plagued major American cities in that era. Recently, Kennedy authored an incisive New York Times op ed titled “What Both the Left and Right Get Wrong about Crime.” 

Kennedy tell us that there’s some truth in the both the left and the right’s characterization of urban crime, but that each sides’ approach, conducted in isolation, is doomed to fail. Rather, he points out that much of the violent crime in blue cities is driven by a very small number of relatively easily identifiable people who are themselves likely to be both the perpetrators and victims of violence. Interrupting those patterns of violent action and reaction requires carefully calibrated, carrot-and-stick interventions targeted directly at those individuals, Kennedy argues. 

Kennedy also emphasizes the deep social harms created by urban drug markets, and he strongly rejects progressive claims that targeted enforcement efforts to disrupt such markets just “move the problem around.” Finally, he tells us that while “broken windows” policing originated as a sensitive and effective approach to preventing serious crime, the concept has been fundamentally discredited as it morphed into the blunt and unevenly applied “zero tolerance” approaches in cities like New York.
