As an early season cold blast moves south, those will be replaced Tuesday with winter weather and frost warnings along the Rockies and western plains, and wind advisories in neighboring states. 580

A letter that's being circulated on Capitol Hill reveals multiple incoming freshmen -- who were largely noncommittal on the House speaker race during their campaigns --- will in fact support Nancy Pelosi.The letter, obtained by CNN, is still being circulated and so far includes 61 signatures from women incumbents and members-elect. It comes as Pelosi is shoring up support from the progressive base this week with endorsements from large and powerful groups, as well as prominent progressives in Congress — a move that will put pressure on wayward Democrats to back her bid.MoveOn, Indivisible and Tax March were among the progressive groups that threw their support behind Pelosi on Thursday and Friday, soon after she met with the Congressional Progressive Caucus. All told, 34 outside groups have backed the California Democrat. Also this week, a group of 100 LGBTQ advocates and leaders endorsed Pelosi in a letter.Rep. Pramila Jayapal, a co-chair of the progressive caucus along with Rep. Mark Pocan, earlier this week would not say whom she's supporting, but she is listed on the women's letter in support of Pelosi.Also on the letter are members-elect like Angie Craig of Minnesota, Ilhan Omar of Minnesota, Dr. Kim Schrier of Washington state, Lori Trahan of Massachusetts, and Jennifer Wexton of Virginia.Below are all the freshmen on the list: 1388

A Las Vegas postal worker says her bosses haven't done enough to address her concerns about a noose hanging in front of a house on her route.Nicole Brown says the home is on a route that she delivers to once a week, and after noticing the noose she stopped delivering to the home."The first day I saw it, I immediately let the supervisor know," Brown said. "I told her I felt threatened for my safety because you never know."Brown said when she delivered on the route she just skipped the street altogether because the home was the only one there. Then the homeowner called the office asking where the mail was.That's when she became concerned."If you want to put racist stuff on your property, okay fine, that is whatever," Brown said.  "Anybody that is delivering shouldn't be subjected to that."Brown said she eventually sat down with her supervisor and union representatives to address the issue.The U.S. Postal Service released a statement when contacted about Brown's concerns. 1021

A Black man who says he was unjustly arrested because facial recognition technology mistakenly identified him as a suspected shoplifter is calling for a public apology from Detroit police. And for the department to abandon its use of the controversial technology.The complaint by Robert Williams is a rare challenge from someone who not only experienced an erroneous face recognition hit, but was able to discover that it was responsible for his subsequent legal troubles.The Wednesday complaint filed on Williams' behalf alleges that his Michigan driver license photo — kept in a statewide image repository — was incorrectly flagged as a likely match to a shoplifting suspect. Investigators had scanned grainy surveillance camera footage of an alleged 2018 theft inside a Shinola watch store in midtown Detroit, police records show.That led to what Williams describes as a humiliating January arrest in front of his wife and young daughters on their front lawn in the Detroit suburb of Farmington Hills.Related: Detroit demonstrators calling for city to cease use of facial recognition technology“I can’t really even put it into words," Williams said in a video announcement describing the daytime arrest that left his daughters weeping. "It was one of the most shocking things that I ever had happen to me.”The 42-year-old automotive worker, backed by the American Civil Liberties Union, is demanding a public apology, final dismissal of his case and for Detroit police to scrap its use of facial recognition technology. Several studies have shown current face-recognition systems more likely to err when identifying people with darker skin.The ACLU complaint said Detroit police “unthinkingly relied on flawed and racist facial recognition technology without taking reasonable measures to verify the information being provided." It called the resulting investigation “shoddy and incomplete," the officers involved “rude and threatening,” and said the department has dragged its feet responding to public-information requests for relevant records.Detroit police and Wayne County prosecutors didn't immediately return emailed requests for comment Wednesday.Related: Detroit police board votes to approve DPD's use of facial recognition technologyDataWorks Plus, a South Carolina company that provides facial recognition technology to Detroit and the Michigan State Police, also couldn't immediately be reached for comment.Police records show the case began in October 2018 when five expensive watches went missing from the flagship store of Detroit-based luxury watchmaker Shinola. A loss-prevention worker later reviewed the video footage showing the suspect to be a Black man wearing a St. Louis Cardinals baseball cap.“Video and stills were sent to Crime Intel for facial recognition,” says a brief police report. “Facial Recognition came back with a hit" — for Williams.At the top of the facial recognition report, produced by Michigan State Police, was a warning in bold, capitalized letters that the computer's finding should be treated as an investigative lead, not as probable cause for arrest.But Detroit detectives then showed a 6-photo lineup that included Williams to the loss-prevention worker, who positively identified Williams, according to the report. It took months for police to issue an arrest warrant and several more before they called Williams at work and asked him to come to the police department. It's not clear why.Williams said he thought it was a prank call. But they showed up soon after at his house, took him away in handcuffs and detained him overnight. It was during his interrogation the next day that it became clear to him that he was improperly identified by facial recognition software.“The investigating officer looked confused, told Mr. Williams that the computer said it was him but then acknowledged that ‘the computer must have gotten it wrong,’” the ACLU complaint says.Prosecutors later dismissed the case, but without prejudice — meaning they could potentially pursue it again.The case is likely to fuel a movement in Detroit and around the U.S. protesting police brutality, racial injustice and the death of George Floyd at the hands of police in Minneapolis. Detroit activists have presented reforms to the city's mayor and police chief that include defunding the police department and ending its use of facial recognition.Providers of police facial recognition systems often point to research showing they can be accurate when used properly under ideal conditions. A review of the industry’s leading facial recognition algorithms by the National Institute of Standards and Technology found they were more than 99% accurate when matching high-quality head shots to a database of other frontal poses.But trying to identify a face from a video feed — especially using the ceiling-mounted cameras commonly found in stores — can cause accuracy rates to plunge. Studies have also shown that face recognition systems don't perform equally across race, gender and age — working best on white men and with potentially harmful consequences for others.Concerns about bias and growing scrutiny of policing practices following Floyd's death led tech giants IBM, Amazonand Microsoft to announce earlier this month they would stop selling face recognition software to police, at least until Congress can establish guidelines for its use. Several cities, led by San Francisco last year, have banned use of facial recognition by municipal agencies. 5490

A Lake Worth family’s home was defaced and targeted on the night of the Florida primary because of their politics, and now they worry what might happen next.Jeanne and Michael Carroll came home Tuesday night to find profanity and an anti-Trump message spray-painted on their home.“We should have freedom of speech, freedom to do whatever we want on our own property,” said Jeanne Carroll, who believes her home was targeted because of the Trump flag flying outside.In the 400 block of S K Street in Lake Worth, pride of country is on full display with American flags flapping in the wind. But the Carroll’s home is the only one with a Trump flag. It's been outside for about eight months without any problems, until Tuesday night."I feel extremely violated," Carroll said.The Carrolls went out to dinner Tuesday, and when they came home they found the words "F*** Trump" spray-painted underneath their front window near the flag."I just don't understand why anyone would take the chance of endangering themselves and coming onto someone else's property just because of a political flag," she said.Less than 24 hours later, Michael Carroll's car was also spray painted. It was tagged with the same anti-Trump message and the letter X."People are so just on opposite sides and it's so divided," neighbor PJ Mahoney said.Mahoney has a sign on her fence supporting a Republican for Governor, and she is thankful no one saw a Trump sign hanging on her house. She feels no one should destroy someone's property, no matter what political party you support."I think people are very selfish and self-centered that if they don't agree with it they think they have the right to do something about it," Mahoney said.That is what now scares Carroll. She fears with the state of politics in the country, things could escalate."What really frightens me is, if they're that bold enough to do something like this, what else is coming in the future?" she said.The couple filed a report with the Palm Beach County Sheriff's Office, but there are no leads. There are security cameras around the house, but they did not catch the culprits.Jeannie said she is standing firm and will not be bullied. She plans to continue to fly the Trump flag but also plans to install more security cameras to better protect her property. 2313
