We could not independently verify these experts’ validation, as neither Goldstone nor Lieberman got back to us.
When we reached out to Kairos, a Miami-based facial recognition software company, Chief Technology Officer Cole Calistra was skeptical about claims of a positive identification. Calistra told PolitiFact that the photos are too grainy "to perform a proper match one way or the other."
James Wayman, the former director of U.S. National Biometric Test Center in the Clinton administration, said proper analysis requires two full-frontal facial images.
"Without such images, no professional face examiner will be willing to render an opinion," he said.
That being said, we had freelance programmer Lucien Gendrot test it out using Kairos’ face recognition API. The software could not verify a match between photos of the unidentified man next to Oswald and young Rafael Cruz, even at a low threshold of a 25 percent match.
In short, as Snopes wrote in an April 2016 analysis of a similar claim, the low-resolution photos are essentially "of dark-haired young men with similar haircuts." That’s speculation, not evidence."
