As part of a new template for relations between the two agencies, the district attorney’s office will provide the police with more than $20 million from drug forfeiture cases to pay for new technology. That money will go for security cameras, fiber-optic information systems and hand-held tablets that will feed police officers data about suspects, Mr. Bratton said.The Police Department, in turn, will provide the district attorney’s Crime Strategies Unit access to more of the data it collects not only on reported crimes but also on suspects, Mr. Bratton said. He called the new approach “extreme collaboration” and illustrated it by clasping his hands together.The commissioner said he envisioned a “seamless web” of information flowing between prosecutors and the police. Prosecutors will have access, for instance, to the network of security cameras on city streets the department uses to solve crimes, as well as the mountains of data collected on police reports, while detectives will receive the granular intelligence about criminal conspiracies gathered by prosecutors as they prepare for trial.
