San Francisco is expected to set a groundbreaking precedent on Tuesday by voting to become the first city in the country to ban police from using facial recognition. Part of the reason: concerns about accuracy. “With Caucasian faces, facial recognition is pretty good. It has a 90 to 95 percent accuracy rate,” explains Darrell West, director of the Center for Technology Innovation with the Brookings Institution. “But with minorities, sometimes the accuracy rate drops to 70 percent.”West also says that once a person’s image is in the database, there’s uncertainty surrounding what it could be used for. A Georgetown law study found 1 in 2 American adults is in a law enforcement face recognition network. Law enforcement has argued the technology helps solve crimes or improve investigations. Agencies across the country can use driver’s license photos or mug shots to match someone's identity. “All it's doing is using something that's readily available,” says Sheriff Bob Gualtieri with the Pinellas County Sheriff’s Department in Florida. But it's not just law enforcement using the technology. Stores, airports and some concert venues are all starting to work it into their operations. It's become so mainstream, Congress is now considering a bill to stop businesses from collecting facial recognition data on customers without their permission. “I think people find it very intrusive that you're just walking down the street or going into the store and somebody's recording your face and then attaching your identity to that image,” West says.If the bill in Congress passes, it would be the first federal law on facial recognition. 1656

Protests are erupting across the country. People are taking to the streets in major American cities calling for change after George Floyd, a black man, died in Minnesota after being restrained by a white police officer. Cameras captured the Minneapolis police officer with his knee on Floyd’s neck with Floyd pleading, “I can’t breathe.” Days after his death, Floyd’s words echoed through downtown Denver with hundreds of people coming together, creating a human wall and blocking freeway access. “The fact that they say that they’re scared or whatever, mother (cuss word) don’t get the job,” said US Army veteran Aubrey Rose. With an American flag hanging upside down on his shoulder, Rose has gone from defending his country to questioning those policing it. “This is important because I risked my life to uphold the constitution and black people’s rights are being walked all over,” he said. While Rose called what happened in Minnesota “ugly” and “unjust,” he believes these protests are both “beautiful” and “necessary.” “It really makes me proud to be an American right now,” he said. “Even with everything going on people came out to support.” Support by protesters making their voices heard. And as the crowd grew and protesters started yelling at police, law enforcement put on riot gear. People were quick to question that decision. “Where was all your gear when (cuss word) white people were storming up to the (cuss word) capitol with AK-47s?,” asked one protester. “Black people peacefully protest and we are reprimanded for it.” While holding signs saying black live matter and chanting blue lives murder, people stopped by this protest, started sitting on top of the cars, giving them a unique view.“I feel like with this outbreak there’s going to be a lot of rebirth within the country,” one man said. “You can’t breathe sometimes but you must move forward.”On Friday, the former officer seen kneeling on Floyd's neck, Derek Chauvin, was arrested and charged with the 36-year-old's murder and manslaughter. 2038

1) McConnell starts by making major concessions Tuesday's trial to remove President Donald Trump from office started with Senate Majority Leader Mitch McConnell making two major concessions to rules that he proposed for the trial: One was to allow each side three days – McConnell previously announced that the two legal teams would only get two days each – to present their opening arguments; the other concession was to change how the Senate would accept evidence. Democrats argued that giving the legal teams only two days, which would have amounted to 12 hours each day, would have forced hearings to go well past midnight. CNN reported that several Republican senators had concerns about condensing a total of 48 hours of testimony into four days. 2) Democratic amendmentsMost of Tuesday’s lengthy trial involved entertaining amendments from Sen. Minority Leader Chuck Schumer to the rules of the trial proposed by McConnell. Many of the amendments involved issuing subpoenas to compel witnesses and testimony from the Trump administration. Every amendment proposed by Schumer failed by a party-line vote, except for one (Republican Sen. Susan Collins voted against killing a procedural proposal).3) Roberts admonishes staffsAt exactly 1 a.m., Chief Justice John Roberts, who is presiding over the Senate trial, admonished members of both the House’s prosecution team and Trump’s legal defense. "I think it is appropriate at this point for me to admonish both the House managers and the president’s counsel in equal terms to remember they are addressing the world’s greatest deliberative body,” Roberts told the teams. Roberts’ comments came after House impeachment manager Adam Schiff, D-Calif., finished his argument on an amendment request to subpoena testimony from ex-National Security Adviser John Bolton. Moments later, the amendment was killed by a 53-47 vote. 4) Rules are now in placeAfter 13 hours of debate, Republicans united behind McConnell to approve the rules. Meanwhile, Schumer's caucus remained united by voting down the rules. The rules now allow for House Democrats to kick off their opening arguments for Trump's removal on Wednesday.5) Pulling an all-nighterThe trial itself got underway at 1 p.m. on Tuesday and went well into the wee hours. It was not until 1:50 a.m. before Roberts adjourned the hearing. In the middle of the evening, McConnell requested that Schumer bundle all of his remaining amendments into one motion. But Schumer opted to continue putting forward multiple amendments to be voted on separately.The 100 senators, members of the House prosecution, Trump’s legal team and Roberts will return to Senate chambers to continue the trial at 1 p.m. ET Wednesday. 2719

A feature that Facebook shut down in the wake of last year's Cambridge Analytica scandal came back to haunt it on Wednesday, when it emerged that hundreds of millions of Facebook users' phone numbers had been found in an unprotected online database.Millions of American Facebook users' phone numbers are believed to be among those found. Facebook said there is no evidence that any accounts were compromised. Even so, the latest discovery is a reminder that even new, stricter security policies can't necessarily address past data leaks or abuses.Until April 2018, people could enter another person's phone number to find him or her on Facebook. The company shut down the feature in the weeks after the Cambridge Analytica scandal broke because it found "malicious actors" had abused the feature to gather public information on Facebook users, a process known as scraping."Given the scale and sophistication of the activity we've seen, we believe most people on Facebook could have had their public profile scraped in this way," Mike Schroepfer, Facebook's chief technology officer, 1095
