“Every law enforcement official has taken the call for reform seriously. They just aren’t on the same page as to how fast they are able to implement the changes,” said Jillian Snider, a retired NYPD officer, adjunct lecturer at John Jay College of Criminal Justice and policy director of R Institute, a Washington-based think tank. 

Snider, who has researched the practices of police departments across the country, said resources spent on collecting and analyzing data to better inform enforcement decisions vary by department. 

Police officials, local governments and community advocates who created the reform plans in Nassau and Suffolk might have “tried to implement too many changes at one time,” Snider said. “It’s a culture that’s been so accustomed to doing things the same way.”
