What does a crime-wracked city do if its most effective strategy against gun violence has also fueled allegations of abuse and corruption?
The answer, in Baltimore, is to try again ─ but this time, more carefully.
Frustrated by the city’s stubbornly high murder rate ─ including a record-setting 2017 ─ Mayor Catherine Pugh fired her police commissioner Friday and replaced him with a career Baltimore cop who promised to expand upon prior efforts at “hot spot policing.”
Baltimore, along with many other big American cities, has a complicated relationship with the tactic, which involves flooding high-crime neighborhoods with officers who target the most violent or chronic offenders. It has proven to curb gun violence, but at a steep price.
After consulting with the Justice Department, Pugh said she has hired a guru of the modern hot spot policing movement: Sean Malinowski, a Los Angeles Police Department commander who advises cities on high-tech policing techniques, including the use of precinct-based “nerve centers” outfitted with software that helps officers predict where shootings will occur. That approach has been credited with Los Angeles' long-term drop in crime, and recent crime reductions in some of Chicago's troubled neighborhoods.
This strategy is a modern iteration of the type of hot spot policing that grew popular during the 1980s, with officers plotting crimes with pins on maps, and expanded in the 1990s and 2000s with computerized Compstat crime-analytics programs. With advances in technology came the use of predictive policing software. Today's versions, including those embraced by Malinowski, rely on the rapid crunching of crime data, along with the use of surveillance cameras and sensors that alert police to the sound of gunfire, and downloading that information to officers' smartphones.
Bill Bratton, the former police commissioner in New York ─ where he introduced the Compstat in 1994 ─ and Los Angeles ─ where he had Malinowski develop predictive policing programs ─ said in an interview that the latest version was "Compstat on steroids."
"We’ve moved forward to the point where we're using algorithms to identify the where, when and who with much more accuracy," Bratton said.
The history of hot spot policing ─ an outgrowth of the "broken windows" philosophy of policing that gave rise to stop-and-frisk techniques ─ is also a tale of the perils of aggressive street enforcement. Several of America's biggest cities, including New York, Los Angeles and Chicago, have used tactics that have been found to be unconstitutional for disproportionately targeting minorities. That has sown enmity in black and Latino communities.
Police leading the new iterations of hot spot policing stress the importance of maintaining community trust. In fact, some say that the modern version reduces the overall number of enforcement interactions police have with people on the street.
"Without sufficient professionalism, oversight and accountability, such units can cause serious harm to individuals in the communities they are supposed to protect and to the department’s reputation, undermining its long-term effectiveness," the researchers wrote.
Baltimore’s new top cop, Darryl DeSousa, who'd served as an assistant commissioner under his predecessor, Kevin Davis, balanced tough talk for criminals with a promise to keep civil rights issues in mind.
"I have a real strong message for the trigger pullers: It’s that we’re coming after them," DeSousa said Friday at a news conference. "It’s going to be accelerated pace. The district commanders in all nine districts know who they are, and we’re coming after them. And I want to let everybody know it’s going to be done in a constitutional manner."
Andrew Ferguson, who studies predictive policing at the University of the District of Columbia David A. Clarke School of Law, said he thinks highly of Malinowski and his approach to hot spot policing. But its success will hinge on whether Baltimore is able to do what it takes to make it work.
"Are they going to invest resources into it? They spent real money in L.A. and Chicago," Ferguson said.
The Baltimore Police Department did not respond to requests for details on DeSousa's plan.
