Amazing, but also a bit scary. This will surely be used for retroactive identification from existing photographs, and will be a free gift for authoritarian law enforcement. Of course such extrapolative technologies are subject to challenge, but criminal juries have a tendency to accept forensic claims at face value notwithstanding their actual scientific reliability. It's partly because of this that if I ever found myself on trial for a crime I didn't commit I'd probably waive my right to a jury trial - laypeople are far too easily fooled.
