  • Detroit has lowest homicide tally in 50 years

    January 2018  |  The Detroit News  

    In 2017, Michigan's biggest city posted its lowest tally of criminal homicides in more than a half-century: 267, Detroit Police Chief James Craig confirmed Monday. The program city leaders cite as a factor in falling crime is the expansion of Operation Ceasefire. Craig said he expects to roll out that program citywide by March. It’s currently operating on the east side and in the 6th Precinct on the west side. "We have got the most advanced system of crime intelligence that the police department has ever had," Duggan said. "They are able to pull data instantly; if a shooting happens at 2 a.m, we have the ability to pull data and have a really good idea which groups are involved and be out the next day responding."

  • New Haven marks lowest homicide number in decades in 2017

    December 2017  |  New Haven Register  

    With only a day left in 2017, New Haven is on pace for the lowest number of homicides in decades. The seven homicides this year — down from 13 in 2016 — would mark the fewest in New Haven since 2003, when the city had eight.
    Both Campbell and Generoso credited the Police Department’s numerous collaborations with the community, and chiefly programs such as Project Longevity and daily interdepartment intelligence meetings, with helping decrease crime rates. Project Longevity combines local, state and federal resources to reduce crime.

  • York City’s shootings drop by half, GVI credited for reduction

    December 2017  |  York Dispatch  

    York City had less than half the shootings in 2017 than it had the year before, according to city officials, who credit the national Group Violence Intervention initiative with reducing those numbers. 

    The GVI initiative, which began in York City in February after more than a half-year of planning, led to city officers, other law enforcement and GVI community partners making more than 500 contacts with city residents, according to Leitzel.

    About 50 or so of those contacts ended with someone being arrested, the lieutenant said, but the vast majority of contacts were positive.

  • Report: Connecticut’s Project Longevity Is Effective Tool Against Gun Violence

    December 2017  |  Hartford Courant  

    A new report from a gun policy group founded by former Democratic Congresswoman Gabrielle Giffords highlights Connecticut’s Project Longevity as one of the most effective programs in the nation at combating gun violence.

    The state-funded Project Longevity, which has an annual budget of $885,000, was launched in 2012 and operates in New Haven, Hartford and Bridgeport, three cities that account for more than 70 percent of gun homicides in Connecticut. The program targets the small segment of each city’s population that is responsible for the majority of gun crime and seeks to intervene before things turn violent.

  • Americans Don’t Really Understand Gun Violence

    December 2017  |  The Atlantic  

    Some police departments do carefully track shootings, but most keep that data internal. In New York City, for example, police track nonfatal shootings rigorously, Aborn said, starting from when victims walk into an emergency room with a gunshot wound. “We really like to unpack shootings,” he said. “It’s almost an epidemiology approach: understanding what’s causing the disease. Without that data, it’s very hard to do that kind of analysis.”

    But other cities can’t tell you how many people are shot in their own jurisdictions, said David Kennedy, the director of the National Network for Safe Communities at the John Jay College of Criminal Justice. That includes many of the biggest cities in the country. When the Major Cities Chiefs Association routinely surveys its members for violent-crime data, only 40 of its 69 member agencies are usually able to provide the number of nonfatal shootings. And when The Baltimore Sun tried last year to compare lethality rates for shootings, it found that only half of the country’s 30 biggest cities even keep that data.

  • A Better Way to Deal With Intimate Partner Violence

    November 2017  |  Governing Magazine  

    In this op-ed for Governing Magazine, IPVI Director Rachel Teicher explains why victims of intimate partner and domestic violence don't trust the criminal justice system, and outlines how procedural justice can improve victim perceptions of law enforcement. "This trust could provide the foundation for a new vision of public safety: safer communities that are empowered by positive, ongoing and successful cooperation with law enforcement. Increased confidence in criminal-justice practitioners improves victim participation and offender accountability, and it provides law enforcement with the resources it needs to address and ultimately reduce these violent crimes."
