Here are the first four paragraphs
> In May 2019, an agent at the Department of Homeland Security received a trove of unsettling images. Found by Yahoo in a Syrian user’s account, the photos seemed to document the sexual abuse of a young girl. One showed a man with his head reclined on a pillow, gazing directly at the camera. The man appeared to be white, with brown hair and a goatee, but it was hard to really make him out; the photo was grainy, the angle a bit oblique. The agent sent the man’s face to child-crime investigators around the country in the hope that someone might recognize him.
> When an investigator in New York saw the request, she ran the face through an unusual new facial-recognition app she had just started using, called Clearview AI. The team behind it had scraped the public web — social media, employment sites, YouTube, Venmo — to create a database with three billion images of people, along with links to the webpages from which the photos had come. This dwarfed the databases of other such products for law enforcement, which drew only on official photography like mug shots, driver’s licenses and passport pictures; with Clearview, it was effortless to go from a face to a Facebook account.
> The app turned up an odd hit: an Instagram photo of a heavily muscled Asian man and a female fitness model, posing on a red carpet at a bodybuilding expo in Las Vegas. The suspect was neither Asian nor a woman. But upon closer inspection, you could see a white man in the background, at the edge of the photo’s frame, standing behind the counter of a booth for a workout-supplements company. That was the match. On Instagram, his face would appear about half as big as your fingernail. The federal agent was astounded.
> The agent contacted the supplements company and obtained the booth worker’s name: Andres Rafael Viola, who turned out to be an Argentine citizen living in Las Vegas. Another investigator found Viola’s Facebook account. His profile was public; browsing it, the investigator found photos of a room that matched one from the images, as well as pictures of the victim, a 7-year-old. Law-enforcement officers arrested Viola in June 2019. He later pleaded guilty to sexually assaulting a child and producing images of the abuse.
Also, this will be done, it is being done. Every city in the world with cameras is making a decision to either discard the footage or use it. Eventually the costs will align for every city in a way that using the footage makes sense. Then they'll do it. Better to think through the issues early, so at least you have the option of thinking through them often.
