Amazon banned police use of its face-recognition technology for a year, making it the latest tech giant to step back from law-enforcement use of systems that have faced criticism for incorrectly identifying people with darker skin.The Seattle-based company did not say why it took action now. Ongoing protests following the death of George Floyd have focused attention on racial injustice in the U.S. and how police use technology to track people. Floyd died May 25 after a white Minneapolis police officer pressed his knee into the handcuffed black man’s neck for several minutes even after Floyd stopped moving and pleading for air.Law enforcement agencies use facial recognition to identify suspects, but critics say it can be misused. A number of U.S. cities have banned its use by police and other government agencies, led by San Francisco last year. On Tuesday, IBM said it would get out of the facial recognition business, noting concerns about how the technology can be used for mass surveillance and racial profiling.It’s not clear if the ban on police use includes federal law enforcement agencies. Amazon didn’t respond to questions about its announcement.Civil rights groups and Amazon’s own employees have pushed the company to stop selling its technology, called Rekognition, to government agencies, saying that it could be used to invade privacy and target people of color.In a blog post Wednesday, Amazon said that it hoped Congress would put in place stronger regulations for facial recognition.“Amazon’s decision is an important symbolic step, but this doesn’t really change the face recognition landscape in the United States since it’s not a major player,” said Clare Garvie, a researcher at Georgetown University’s Center on Privacy and Technology. Her public records research found only two U.S. agencies using or testing Rekognition.The Orlando police department tested it, but chose not to implement it, she said. The Washington County Sheriff’s Office in Oregon has been the most public about using Rekognition, but said after Amazon’s announcement Wednesday that it was suspending its use of facial recognition indefinitely.Studies led by MIT researcher Joy Buolamwini found racial and gender disparities in facial recognition software. Those findings spurred Microsoft and IBM to improve their systems, but irked Amazon, which last year publicly attacked her research methods. A group of artificial intelligence scholars, including a winner of computer science’s top prize, last year launched a spirited defense of her work and called on Amazon to stop selling its facial recognition software to police.A study last year by a U.S. agency affirmed the concerns about the technology’s flaws. The National Institute of Standards and Technology tested leading facial recognition systems -- though not from Amazon, which didn’t submit its algorithms -- and found that they often performed unevenly based on a person’s race, gender or age.Buolamwini on Wednesday called Amazon’s announcement a “welcomed though unexpected announcement.”“Microsoft also needs to take a stand,” she wrote in an emailed statement. “More importantly our lawmakers need to step up” to rein in harmful deployments of the technologies.Microsoft has been vocal about the need to regulate facial recognition to prevent human rights abuses but hasn’t said it wouldn’t sell it to law enforcement. The company didn’t respond to a request for comment Wednesday.Amazon began attracting attention from the American Civil Liberties Union and privacy advocates after it introduced Rekognition in 2016 and began pitching it to law enforcement. But experts like Garvie say many U.S. agencies rely on facial recognition technology built by companies that are not as well known, such as Tokyo-based NEC, Chicago-based Motorola Solutions or the European companies Idemia, Gemalto and Cognitec.Amazon isn’t abandoning facial recognition altogether. The company said organizations, such as those that use Rekognition to help find children who are missing or sexually exploited, will still have access to the technology.This week’s announcements by Amazon and IBM follow a push by Democratic lawmakers to pass a sweeping police reform package in Congress that could include restrictions on the use of facial recognition, especially in police body cameras. Though not commonly used in the U.S., the possibility of cameras that could monitor crowds and identify people in real time have attracted bipartisan concern.The tech industry has fought against outright bans of facial recognition, but some companies have called for federal laws that could set guidelines for responsible use of the technology.“It is becoming clear that the absence of consistent national rules will delay getting this valuable technology into the hands of law enforcement, slowing down investigations and making communities less safe,” said Daniel Castro, vice president of the industry-backed Information Technology and Innovation Foundation, which has advocated for facial recognition providers.ángel Díaz, an attorney at New York University’s Brennan Center for Justice, said he welcomed Amazon’s moratorium but said it “should have come sooner given numerous studies showing that the technology is racially biased.”“We agree that Congress needs to act, but local communities should also be empowered to voice their concerns and decide if and how they want this technology deployed at all,” he said.____O’Brien reported from Providence, Rhode Island. 5514

After a 29-year-old man drove a truck into a Manhattan crowd on Tuesday, killing eight and wounding almost a dozen in the deadliest terror attack to hit the city since 9/11, New Yorkers made it clear that they refused to be intimidated.Families celebrated a traditional Halloween Parade hours after the attack, surrounded by police officers armed with long guns while dozens of local and federal law enforcement officers were still investigating the attack."This was an act of terror, and a particularly cowardly act of terror," New York Mayor Bill de Blasio said, "aimed at innocent civilians, aimed at people going about their lives who had no idea what was about to hit them." 687

After issuing previous guidance that encouraged schools to close in areas with high transmission of the coronavirus, the CDC is now emphasizing that schools reopen this fall.The guidance issued on Thursday is in line with a Trump administration priority to reopen schools this fall.“It is critically important for our public health to open schools this fall,” said CDC Director Dr. Robert R. Redfield. “The CDC resources released today will help parents, teachers and administrators make practical, safety-focused decisions as this school year begins. I know this has been a difficult time for our Nation’s families. School closures have disrupted normal ways of life for children and parents, and they have had negative health consequences on our youth. CDC is prepared to work with K-12 schools to safely reopen while protecting the most vulnerable.”Now in areas with, as the CDC calls it, "substantial, uncontrolled transmission" of the coronavirus, "Schools should work closely with local health officials to make decisions on whether to maintain school operations. The health, safety, and wellbeing of students, teachers, staff and their families is the most important consideration in determining whether school closure is a necessary step. Communities can support schools staying open by implementing strategies that decrease a community’s level of transmission. However, if community transmission levels cannot be decreased, school closure is an important consideration."In areas with substantial, controlled transmission, "Significant mitigation strategies are necessary." In addition, social distancing and face covering policies should be implemented, the CDC said.Previous guidance called for schools in areas with substantial community transmission (the CDC did not distinguish between uncontrolled or controlled) to, "Implement extended school dismissals (e.g., dismissals for longer than two weeks). This longer-term, and likely broader-reaching, dismissal strategy is intended to slow transmission rates of COVID-19 in the community. During extended school dismissals, also cancel extracurricular group activities, school-based afterschool programs, and large events."In previous guidance, the CDC called on schools to keep students 6 feet apart. But many classrooms do not have the space to properly socially distance students. The Trump administration’s response appears to be a 5 billion request to Congress. President Donald Trump said that the funds, in part, could be used for schools to open additional spaces and hire additional staff in order to help space students.The CDC said that the “best available evidence from countries that have opened schools indicates that COVID-19 poses low risks to school-aged children, at least in areas with low community transmission, and suggests that children are unlikely to be major drivers of the spread of the virus.”But that guidance contradicts a South Korean study published by the CDC earlier this week.The study said that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, that school closures and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children.“The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.In its new guidance, the CDC said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”But the CDC also weighed the concerns of the coronavirus against providing physical activity, food and safety for students. The CDC said studies project that the childhood obesity rate would increase by 2.4% if schools remained closed through December.This guidance comes as cases in the US steadily increased earlier this month, prompting coronavirus death counts to rise in recent days. The US had back to back days of more than 1,000 people reportedly dying from coronavirus-related illnesses, according to Johns Hopkins University.To read the CDC’s latest guidance, click here. 5184
