Cure Violence staffs hot blocks with interrupters who stop shootings like an outbreak
An epidemiologist staffs violent districts with trusted mediators who interrupt shootings — independent evaluations found 41–73% fewer shootings.
Cure Violence Global
What it had to solve
In 2000 Gary Slutkin, an epidemiologist who once ran Uganda's AIDS program, founded CeaseFire in Chicago. He argued that shootings spread person to person through exposure and retaliation, so prevention should mirror contact tracing rather than rely only on arrests.
How it works
Gary Slutkin spent years treating tuberculosis and AIDS in Africa, where the winning move was finding infected people and stopping the chain of transmission. Back in Chicago he looked at shooting data and saw the same shape: violence clustered, copied and spread through exposure, with retaliation producing the next case. In 2000 he founded CeaseFire to treat the outbreak instead of just policing it.
The model hires people the streets already trust. 'Violence interrupters' — often former gang members and ex-offenders — detect lethal disputes before they escalate, respond to every shooting to cool down emotions, and follow up so the conflict does not reignite. Outreach workers and clergy run a parallel campaign to change expectations, making nonviolent response the group's norm rather than the exception.
Independent evaluation found the approach moved the numbers. Shootings and killings fell by 41–73% in covered Chicago and Baltimore communities, and retaliation murders fell 100% in five of the eight Chicago areas studied; later reporting put reductions as high as 70% in some neighborhoods. The organization, renamed Cure Violence, spread to Baltimore, New York and cities abroad.
Why it lands
- The disease frame redirects effort from punishment to prevention: find the conflict, interrupt it, treat the 'patient' before the outbreak grows.
- Hiring credible former offenders solves the trust problem no police officer can — the people at risk listen to messengers who once lived the life.
- Responding to every shooting blocks the retaliation loop, which is where most of the next shootings come from.
- Changing what the peer group expects turns prevention into social pressure: violence stops being brave and starts being uncool.
What it did
An independent evaluation of CeaseFire cited by New Scientist in 2009 found shootings and killings fell 41–73% in covered Chicago and Baltimore communities, with retaliation murders down 100% in five of eight Chicago areas. The Trace reported reductions of up to 70% and expansion to Baltimore, New York and beyond.
What you can take
Give prevention a disease metaphor with a concrete job — interrupt transmission — and the neighborhood itself becomes the workforce instead of the suspect.
Since then
Cure Violence grew from CeaseFire's Chicago start into an internationally adopted model. By 2009 representatives of about 30 cities had visited and training had begun in at least six, with deployments from Brazil and the Caribbean to Iraq, where the team said it had defused 100 events in a year. The 2011 documentary The Interrupters followed three of CeaseFire's workers through a year of mediations, and cities kept importing the approach as an alternative to enforcement alone.
