As CBS2’s Tony Aiello reports, a constant stream of data, surveillance video, and human intelligence flows into the Westchester County Real Time Crime Center. It’s an ambitious effort to monitor crime and response from 40 separate local police departments, some with historic rivalries.

“We have seen an increased cooperation throughout the years with the sharing of information and intelligence. Now what I’m seeing even greater is that we actually have resources and manpower going between the different jurisdictions,” said Mount Vernon Police Commissioner Glenn Scott.

“We will utilize a precision policing and precision prosecution model, targeting repeat violent offenders,” said Westchester DA Mimi Rocah.

Rocah says criminals don’t hesitate to cross city lines. Cops from the three cities will be posted at the center to work together.

“Somebody has a question about something that happened in another jurisdiction, we have someone right in the room that can answer that question,” said Westchester Department of Public Safety Commissioner Thomas Gleason.

“We are laser focused on this issue with point people, regular meetings, and resource sharing,’ Rocah said.

They’re sending the message that not only are the cops watching, they’re working together, knowing an arrest in one jurisdiction could prevent a crime in another.
