ORLANDO, Florida — The FBI has invested considerable energy in recent months in marketing a massive new biometric database to local cops, whom the agency will rely on to help feed it billions of fingerprints, palm prints, mug shots, iris scans and images of scars, tattoos and other identifiers.

But it took senior FBI consultant Peter Fagan just nine words this week to capture the ambitious scope of the agency’s aims with the new system, which is gradually replacing traditional fingerprint identification with facial recognition and other biometric identifier technology.

“What happens in Vegas doesn’t stay in Vegas anymore,” Fagan told a roomful of police executives at the annual International Association of Chiefs of Police Conference in Orlando on Tuesday.

He said that reaching the FBI’s goal of better tracking criminal suspects from town to town depends on local cops’ ability to adopt increasingly sophisticated new technologies and to share their data with federal law enforcement. He urged police to begin to “pack the record[s]” by collecting as many high-quality biometric identifiers from arrested criminal suspects as possible.

“We’re not only talking mug shots,” he said. “We’re talking scars, marks, tattoos and other descriptors. You can take up to 25 images [per arrest]. It used to be 10, but now you can take up to 25,” he said. “The upside is that every mug shot you collect is going to be searched against an unsolved crime.”

Oftentimes, Fagan told police, crime victims “remember tattoos but don’t remember anything else” about their assailants. Ultimately, “we should be working towards taking every biometric at every event,” he said, using an industry term for criminal processing.

The FBI’s database, known as Next Generation Identification (NGI), is just one of a dizzying array of investigative innovations being hawked to U.S. law enforcement agencies large and small, nationwide. While technology has transformed nearly every industry, few have changed as rapidly — or with as much federal and corporate encouragement — as local law enforcement.

That fact was evident last weekend in the main exhibit hall of the cavernous Orlando County Convention Center, where hundreds of vendors sold everything from ballistic underwear and high-powered weaponry to an 18-wheel mobile command center and analytic software that tracks gang members’ communications on social media.
