NEW YORK (AP) — Walmart said in a press release that the ammunition and firearms removed from displays at U.S. stores on Thursday was returned to the sales floor on Friday.“After civil unrest earlier this week resulted in damage to several of our stores, consistent with actions we took over the summer, we asked stores to move firearms and ammunition from the sales floor to a secure location in the back of the store in an abundance of caution," the company stated in a news release. "As the current incidents have remained geographically isolated, we have made the decision to begin returning these products to the sales floor today.”Walmart said on Thursday that it had removed ammunition and firearms from displays at U.S. stores, citing "civil unrest" in some areas. The nation's largest retailer, based in Bentonville, Arkansas, sells firearms in about half of its 4,700 stores. The discounter said the items remained available for purchase by customers. Walmart made a similar move in the wake of the police killing of George Floyd that set off sometimes violent demonstrations against police brutality and injustice against Blacks. Last year, Walmart stopped selling handgun and short-barrel rifle ammunition while requesting that customers not openly carry firearms in its stores, even where state laws allow it. The company also ended the sale of handguns in Alaska, the only state where the discounter sold them. 1432

NEW YORK -- The white woman who called 911 on a Black man in Central Park back in May also made a second previously undisclosed phone call accusing the man of trying to assault her, the Manhattan district attorney revealed during a court appearance Wednesday.Amy Cooper was caught on camera calling 911 and falsely accusing Christian Cooper of threatening her life during an argument over leashing her dog in an area of the park where it is required. Amy and Christian Cooper are not related.Amy Cooper appeared in court Wednesday on a charge of falsely reporting an incident. According to the Manhattan district attorney’s office, the charge is related to the a second phone call, which was not heard on camera.During that call to 911, Amy Cooper repeated her initial accusation and added that the man “tried to assault her," District Attorney Cyrus Vance said.When officers arrived, Amy Cooper admitted that the man had not tried to assault her and had not come into contact with her, according Vance.Amy Cooper appeared virtually before a judge Wednesday, but she did not enter a plea. The case was adjourned until Nov. 17.The district attorney’s office is also exploring the option with Amy Cooper’s defense team of having her participate in an educational program to take responsibility for her actions and educate others on preventing future incidents.The now viral video was taken on May 25 by Christian Cooper. Following the incident, Amy Cooper was dubbed "Central Park Karen" — Karen being a term for women seen as acting racist and entitled.Christian Cooper, an avid bird watcher, had repeatedly told Amy Cooper to leash her pet. Instead, she called 911.Since the video went viral, Amy Cooper was fired by her employer and voluntarily surrendered custody of her dog to the rescue organization she adopted it from. The dog was later returned to her.She has also apologized for her actions and claimed she is not racist.The incident led to Gov. Andrew Cuomo signing an order that criminalizes making false, race-based 911 reports.This story was originally published by Lauren Cook and Rebecca Soloman at WPIX. 2126

NORTH READING, Mass. – An off-duty police officer in Massachusetts is being credited with saving three people from an early morning house fire on Tuesday.The North Reading Police Department says Sgt. Thomas Encarnacao had just finished his shift and was on his way home when he noticed flames emerging from inside the home.After alerting dispatch of the fire, Encarnacao entered the home to alert the residents. He was able to locate a man sleeping on a coach at the front of the house and helped him outside to safety, according to police.The man told Encarnacao and other officers who had arrived to help that there were two more residents in the home, a 13-year-old boy sleeping in a back bedroom and a man in the basement of the home.The man in the basement was able to get out on his own after officers alerted him, but police say first responders had to pull the boy out through a window of a smoke-filled room.All three residents were evaluated by EMS at the scene and didn’t go to the hospital. No firefighters were injured. One officer suffered a cut to his hand while attempting to breach a basement window.Firefighters were able to put the blaze out, but the house ended up sustaining smoke, fire and water damage. Police say the residents were displaced and are being assisted by family members.The origin and cause of the fire is under investigation.“The work of the three officers this morning was truly courageous, and I am incredibly proud of them,” said Police Chief Michael Murphy. “Sgt. Encarnacao took decisive and immediate action, which very likely saved the lives of the residents inside the house. Once he got the first resident out, all three officers went back into the house, without protective gear, to look for additional residents. Their actions to get all of the residents out safely was truly heroic.” 1841

NORFOLK, Va. - An Old Dominion University student wants to see more African-American Physicists.She and others are making efforts to make this a reality and they are looking for mentors in the Hampton Roads community.“I love Accelerated Physics,” Kat Watkins, a junior at ODU said. She is passionate about physics and has been since childhood.She recently started the group Society of Black Physicists at ODU.The American Institute of Physics found that fewer than four percent of bachelor’s degrees went to black students for Physics and there's a nationwide effort to change this and to increase the number of African American Physicists.“Knowing all of this, hearing these numbers and being in a very small population of people, it's very hard to find the representation,” said Watkins.With the support of her adviser Dr. Matthew Nerem, an ODU Professor, and other students, she created the organization.“To provide a place for a person of color to feel home, you may be the only one in your class, you may be the only one that you see, but your experience is not singular, you're not alone. So that's why I started S.B.P.,” said Watkins.Physics student Jade Hooper is also part of the group. “Right now, I'm pretty much, if not in all of my classes, most of them, not just the only black female, but the only black person in the classroom and so from that standpoint, it kind of puts me in a position where sometimes I don't feel comfortable,” said Hooper, “My colleagues who are not the minority, they never have to go into a classroom or a building and wonder am I going to be the only white person in the classroom.”“If we want to have a proper representation, based on the population size, we need to bring up the number of Ph.D... by like almost eight times,” said Dr. Nerem.Watkins said her group is looking for mentors throughout the Hampton Roads region to help the students. She said the students also are looking at ways to reach children in hopes of getting kids interested in Science, Technology, Engineering, and Math.“We really just want to spread our roots out into the community,” said Watkins, “We want to inspire little ones. We want to inspire young minds too.”“It’s very important that these teens and the students can see a representation, somebody like me and Kat who will make it in this field so that they have somebody to look up to,” said Hooper.“Studying physics just gives people the opportunity to try and explore the universe, what we're composed of,” said Dr. Nerem.You don't have to be African American to join the group or mentor, you just need to support their mission: "The mission of the Society of Black Physicists is to promote the professional development and well-being of ethnic minority STEM students within the international scientific community and within society at large. SBP seeks to develop and support efforts to increase opportunities for ethnic minorities and People of Color in physics and to increase their numbers and visibility of their scientific work. It also seeks to develop activities and programs that highlight and enhance the benefits of the scientific contributions that People of Color provide for the international community."“I would love to come back in 20 years to ODU and walk into the mathematical methods of physics class and see half of the class be people of color, that will be incredible. That would be awesome,” said Watkins.Click here to learn more and to visit their website.This story was first reported by Margaret Kavanagh at WTKR in Norfolk, Virginia. 3547

NEW YORK (AP) — Democratic presidential candidate Elizabeth Warren on Friday rolled out a proposal to break up the biggest U.S. technology companies, saying they have too much control over the economy and Americans' lives.In her pitch to rein in the influence of tech giants, the Massachusetts senator envisions legislation targeting companies with annual worldwide revenue of billion or more, limiting their ability to expand and forcing parts of Google and Amazon's current business structure to operate as separate entities.As president, Warren said she would pick regulators who would seek to break up what she called "anti-competitive mergers" such as Facebook's recent purchase of Instagram and Amazon's acquisition of Whole Foods.She made the pitch ahead of a rousing town hall appearance Friday in the New York City neighborhood where Amazon recently scrapped plans to open a new headquarters.It's Warren's latest effort to shape the policy agenda for the rest of the Democratic presidential primary, coming after earlier announcements of a "wealth tax" plan on households with high net worth and a universal child care proposal.Her tech agenda, coming at a time of rising public concern about the growing power of the dominant players, could force the rest of her rivals for the 2020 nomination to follow her lead.During remarks before a crowd of more than 1,000 people in Queens, Warren touted elements of her new tech-industry plan as part of her stump speech. She took aim at Amazon's search for lavish economic incentives from cities competing for its headquarters, likening the company's efforts to pit areas against each other to the dystopian film "The Hunger Games.""That's what's wrong with the system. It's not just that big tech companies like Amazon have enormous market power, which they do. They have enormous political power," Warren told the audience, describing the industry's lobbying expenditures as a "good return on investment if they can keep Washington from enforcing the antitrust laws."It remains to be seen whether Warren will introduce legislation in the current Congress aligning with the first element of her plan. A spokeswoman, Kristen Orthman, said a bill introduction was not imminent.Warren's latest policy proposal also promised to be a central element of her scheduled visit Saturday to the South by Southwest conference in Austin, Texas.Sen. Kamala Harris of California represents the tech industry's home state, while Sen. Cory Booker has come under scrutiny for his past ties to tech companies — though he's stepped up his criticism of the industry in recent years.Facebook spokeswoman Monique Hall said the company had no comment on Warren's proposal. Representatives for Google, Amazon, Microsoft and Apple did not immediately respond to a request for comment. 2822
