How Communities and Law Enforcement Can Work Together Using Data

In the heart of Rochester, New York, a remarkable story of collaboration is unfolding between community leaders and the Rochester Police Department (RPD). Meet one such leader, Diane Trentini, who has a lifelong passion for using technology to solve problems and improve lives.

Raised on a family farm in Ontario, New York, Diane learned early the value of community. Her father, a school principal in the city of Rochester who would bring students home to experience farm life, instilled in her a deep appreciation for connection and community–for bridging divides and noting the way urban neighborhoods can coalesce around a corner store and the simple niceties that transpire there. 

With a background in computer science and years of experience in engineering and technology, including human service, health, and education domains, Diane was asked to join a Community Advisory Board to work with the RPD to bring to life Commons. Commons is a data platform that answers basic questions about how the RPD does its work. How long does it take officers to show up after a call for help? How many incidents involve the use of force? How many officers are working overtime? 

For Diane, getting information out to the public is a moral imperative. “As a taxpayer, I support our public servants–I want to know how well they’re doing this really hard work, and also if we’re taking good care of them.”

Which gets back to this idea that at the heart of data are people. As Diane notes, getting answers in data is more than just numbers – it’s a bridge and conversation starter.

“Data can always get better,” she explains, “but it provides a crucial foundation for understanding.” Her approach isn’t about creating perfect data dashboards out of the gate, but about continuous improvement and meaningful insights that can drive real change.

The conversations between the CAB and RPD weren’t always easy. They delved into tough topics like use of force, community safety, and systemic challenges. But throughout, Diane saw people listening, understanding, and working towards a common goal.

“The most exciting part of the experience,” she reflects, “was the authentic intention of everyone around the table to serve each other well and to serve the community well.” 

Diane’s vision for Rochester goes beyond Commons. She hopes to see neighborhoods where police and community members know and support each other, where data can help identify needs and create more supportive services. This vision is ambitious, but Commons is a promising start.

 “When you work in community toward common goals,” Diane says, “the probability of success goes up so much higher. It’s about creating lasting connections and fostering understanding, one data point at a time.“
