The study is “really demonstrating a way to take what we already know to be effective… and translating it into the digital realm,” Sheana Bull, professor and chair of the Department of Community and Behavioral Health at the Colorado School of Public Health in Denver, said.
“I think it does have a lot of potential and a lot of promise,” said Bull, who wasn’t involved with the new study.
The federal government has access to a massive database of 25 years of AT&T phone data, NBC News has confirmed, as part of a secret program in which phone company employees work alongside local and federal law enforcement agents to track the phone calls of suspected drug dealers.
As first reported by the New York Times, the Hemisphere Project is at least six years old and has access to the data from every call coming through an AT&T switchboard back to 1987. The pool grows by billions of calls a day, includes information on the location of callers, and is larger than the controversial database maintained by the NSA, which goes back five years.
