The nationwide group behind the Women's March is organizing a national school walkout following Florida's high school shooting.The group is calling for students, teachers and parents to take part in walking out of school for 17 minutes - a nod to the 17 lives lost in the Feb. 14 shooting - to "protest Congress' inaction to do more than tweet thoughts and prayers in response to gun violence.""Enough: National School Walkout" is being scheduled for 10 a.m. local time across the U.S. on March 14.Organizers posted the event to Facebook with a message, reading in part:"We need action. Students and allies are organizing the national school walkout to demand Congress pass legislation to keep us safe from gun violence at our schools, on our streets and in our homes and places of worship." 804

The man responsible for the Strasbourg terror attack was killed by police on Thursday, a spokesman for the Paris prosecutor's office said.Cherif Chekatt, 29, is accused of killing at least three people and wounding 13 others in the terrorist attack near the Christmas market in Strasbourg. French prosecutors said the suspect shouted the Arabic phrase "Allahu Akbar," meaning "God is greatest," at the time of the attack.He was killed after a two-day manhunt that prompted a curfew in the eastern French city near the German border and forced the country to raise its national security threat level. Hundreds of police and military officers across three European countries were involved in the search.The French National Police thanked the public for their assistance in finding Chekatt."Thank you for your alerts which allowed us to find the wanted individual," the National Police said on Twitter.Authorities said Chekatt entered the perimeter of the famed market, one of the oldest in Europe, by the city's Corbeau Bridge and started shooting at passers-by on the Rue des Orfèvres around 8 p.m., when many were in the middle of their Christmas shopping.Anti-terror police flooded the market and tried to arrest the suspected gunman. He exchanged fire with security forces, suffering an injury to his arm. Chekatt used a handgun and a knife to kill people, Paris Prosecutor Remy Heitz said.The suspected gunman then jumped into a taxi and fled the scene, Heitz said.Soon after the attack, more than 700 police and military officers across three European countries joined the search and France raised its national security threat level to its highest status: "emergency terror attack."On Thursday, French police evacuated buildings and cordoned off the area where the suspected gunman fled. Chekatt has an extensive criminal background that includes 27 convictions in France, Germany and Switzerland, mostly for acts of robbery and violence.In 2017, he was deported from Germany to France after the Interior Ministry in the German state of Baden-Wuerttemberg confirmed he had been convicted of break-ins and serious theft in 2016 and spent time in a German prison.The suspected shooter also was known to prison officials for being radicalized and for his proselytizing behavior in detention in 2015, Paris prosecutor Heitz said, adding that Chekatt had been incarcerated multiple times.Chekatt was born in Strasbourg, according to CNN affiliate BFM.He was on a French watch list called a "Fiche S" surveillance file. The "Fiche S" is a French terror and radicalization watch list that includes thousands of people, some of whom are under active surveillance, meaning they are on law enforcement's radar.Hours before the attack, French gendarmes tried to bring in Chekatt but found he wasn't home, a spokesperson for France's National Police told CNN earlier this week, without providing further details. 2932

The principal of Marjory Stoneman Douglas High School, where 17 people were killed in a February 14 school shooting, said students who walk out today will be punished.Principal Ty Thompson told the students during yesterday's announcements that if they leave campus they will face disciplinary action. A teacher told CNN that the disciplinary action will be an unexcused absence.But that isn't stopping the students: Most of the teachers said they expect a good number of the students to walk out of the classrooms, but they aren't so sure how many will leave campus.However, the student body isn't exactly unified on this walkout. While many of the most vocal students are promoting the walkout, some other students feel conflicted since the walkout marks the Columbine shooting anniversary. Columbine leaders have pushed back against a walkout, asking students to treat the day as a day of service and not just a day to walk out.At Stoneman Douglas, some of the students are planning to do acts of service on campus instead of actually walking out.  1064

The major boom of online grocery ordering shows no signs of slowing down. More than six months into the COVID-19 pandemic, industry experts say the new convenience of ordering groceries through an app is here to stay. "In fact, it's been a huge acceleration. All of our clients that we serve, and we serve some of the biggest supermarkets in North America and the world, they picked up three times the volume that they were doing before this pandemic. And, in fact, more of them didn’t picked up more volume because they couldn't just fulfill enough orders at a time," said Max Pedro, the co-founder and president of Takeoff Technologies. Takeoff Technologies creates automated grocery fulfillment software for some of the biggest grocery chains in the country, including Albertsons, Safeway and Shoprite. The technology requires supermarkets to build a 10,000-square-foot warehouse directly behind their store. When a shopper places an online grocery order at one of these stores, the robots fulfill the order, automatically placing the items in bags, ready for the customer."What happens is those robots bring those individual items to a human being, but those items are coming to a person. They're suddenly making people 13 times more productive than if they have to roam a supermarket aisle to assemble that order," said Pedro.The company has already hit their five-year goal in just four months. "And it’s happened really fast and what’s also happening is we know that consumers are not going back to their previous behaviors. We forcefully trained many, many people to buy their supermarket carts online and they're sticking to it," said Pedro.Laurentia Romaniuk, an Instacart Trends Expert, agrees. "We've seen customers continue to use our site. It seems like online grocery is really here to stay. It's interesting because online grocery has existed in other countries for decades and people have built habits around it in other countries and I think, finally, now America is getting on board with the online grocery trend," said Romaniuk.Instacart, which offers grocery delivery service for a fee from a number of grocery stores across the country, says use of their site went up exponentially at the start of the pandemic. Now that we're in the fall, parents and children are still working and taking classes from home and the need to get groceries delivered or gathered for them, is still there. "Yes, customers are going online and shopping online and becoming more comfortable with that, but also hobbies and habits and eating patterns are changing," said Romaniuk.Pedro says pre-pandemic, only 10% of the market was buying online. It's now grown to 27%. "Remind you that four years ago, the U.S. market was half-a-percent online. Grocery is a really rough category to offer online and still maintain those low prices. Now, with these capabilities and that further need of getting the convenience factor, things have just taken off," said Pedro. Pedro suspects the entire retail industry will soon start reinventing itself, developing technology to offer more delivery and pick-up options to better serve customers who no longer want to go shopping in person. 3181

The list of recalled hand sanitizers is growing. The Food and Drug Administration (FDA) has named dozens that contain methanol, which can cause blindness or hospitalizations if absorbed through skin.A consumer watchdog tells us these products are not FDA approved. That's because in March, the agency allowed companies that never made hand sanitizer to make it in order to meet demand. They just had to agree to follow the rules.“So, guess what happened? Some of them didn't follow the rules, either intentionally or unintentionally, and so then, they started getting reports from the poison control centers of people getting sick from methanol in hand sanitizer instead of ethanol,” said Teresa Murray with U.S. PIRG.Murray says many of the recalled products have been made in Mexico. But as part of the temporary guidelines, companies don't have to disclose where the sanitizers were manufactured. So, it's hard for consumers to tell which products might be dangerous.Murray says if you can't tell where the product was made, don't buy it and don't use it if it's already in your home. To be safe, stick with brand names you recognize for now.Murray has found most stores and online retailers have pulled products on the FDA list, but you should still be careful depending on where you shop.“I would caution anyone from buying anything that's on an end-cap clearance aisle, or anything that's from a super discount store,” said Murray. “There may be a reason why one of the mainstream retailers is no longer selling it.”Murray says it's always important to keep hand sanitizers out of reach for kids and pets, but now, even more so.If ingested, methanol can cause even more health problems.Click here to learn more from the FDA. 1738
