In what may be the first known case of its kind, a faulty facial recognition match led to a Michigan man's arrest for a crime he did not commit. From a report: On a Thursday afternoon in January, Robert Julian-Borchak Williams was in his office at an automotive supply company when he got a call from the Detroit Police Department telling him to come to the station to be arrested. He thought at first that it was a prank. An hour later, when he pulled into his driveway in a quiet subdivision in Farmington Hills, Mich., a police car pulled up behind, blocking him in. Two officers got out and handcuffed Mr. Williams on his front lawn, in front of his wife and two young daughters, who were distraught. The police wouldn't say why he was being arrested, only showing him a piece of paper with his photo and the words "felony warrant" and "larceny." His wife, Melissa, asked where he was being taken. "Google it," she recalls an officer replying. The police drove Mr. Williams to a detention center. He had his mug shot, fingerprints and DNA taken, and was held overnight. Around noon on Friday, two detectives took him to an interrogation room and placed three pieces of paper on the table, face down. "When's the last time you went to a Shinola store?" one of the detectives asked, in Mr. Williams's recollection. Shinola is an upscale boutique that sells watches, bicycles and leather goods in the trendy Midtown neighborhood of Detroit. Mr. Williams said he and his wife had checked it out when the store first opened in 2014.

The detective turned over the first piece of paper. It was a still image from a surveillance video, showing a heavyset man, dressed in black and wearing a red St. Louis Cardinals cap, standing in front of a watch display. Five timepieces, worth $3,800, were shoplifted. "Is this you?" asked the detective. The second piece of paper was a close-up. The photo was blurry, but it was clearly not Mr. Williams. He picked up the image and held it next to his face. "No, this is not me," Mr. Williams said. "You think all Black men look alike?" Mr. Williams knew that he had not committed the crime in question. What he could not have known, as he sat in the interrogation room, is that his case may be the first known account of an American being wrongfully arrested based on a flawed match from a facial recognition algorithm, according to experts on technology and the law. A nationwide debate is raging about racism in law enforcement. Across the country, millions are protesting not just the actions of individual officers, but bias in the systems used to surveil communities and identify people for prosecution.

I noticed that there are many other applications out there that use Tor as a proxy as well (Janus VM, ChrisPC, etc.) Are any of them more secure than the original Tor bundles, or am I just wasting my time trying these other applications? Is there anything more secure than Tor, as far as anonymous browsing goes?"

Several readers let us know about a pair of British researchers who found a workaround to patents covering drugs used to treat hepatitis C. The developers intend to produce a drug cheap enough to supply to people in the poorest parts of the world. The scientists found another way to bind a sugar to interferon, producing a drug they say should be as long-lasting and effective as those sold (at $14,000 for a year's supply) by patent holders Hoffman-La Roche and Schering Plough. Clinical trials could begin by 2008. The article quotes developer Sunil Shaunak of Imperial College London: "We in academic medicine can either choose to use our ideas to make large sums of money for small numbers of people, or to look outwards to the global community and make affordable medicines."
