This year, the number of school shootings in the United States has dropped tremendously because of the pandemic.According to the Center for Homeland Defense and Security, there has only been one shooting inside a school building since March; an accidental discharge of a firearm inside North Forney High School in Forney, Texas that happened before pandemic shutdowns began.It may be one silver lining in a year many wish to forget.But just because numbers are down, does not mean schools are not still prioritizing active shooter drills.According to Everytown for Gun Safety, a public advocacy group, 95 percent of K-12 schools implement active shooter drills, but the number can vary by state. For instance, in New York State, schools are required to have four lockdown drills per year, whereas in New Jersey the requirement is two.Since the pandemic started, most states have required those same number of drills despite some students choosing to learn from home, in-person restrictions, and social distancing.“We had to redesign the entire drill,” said John McDonald, executive director of security and emergency management at JeffCo Public Schools in Colorado. “We had to redesign what it looked like. How do you socially distance when you’re locking down?”McDonald laid the blueprint for school safety across the country when he was brought in by the JeffCo Public School District to implement new safety measures after the Columbine School Shooting in 1999.In the COVID-19 world, students in his school district are now learning about active shooter drills through a three-minute video presentation he helped design.“We have kids learning [these active shooter lessons] since kindergarten,” said McDonald. “So, this helps supplement that and reinforce that muscle memory.”In the Syracuse School District in New York, however, the drills are a little different than in Colorado.“I think that there’s always a need to balance the safety of the potentially very worst day with the challenges of safety and student well-being that schools face every single day,” said Jaclyn Schildkraut, a criminal justice professor at SUNY-Oswego.Schildkraut helped the Syracuse school district redesign its plans following COVID-19. Instead of the normal drills, where a full class might huddle together out of sight of windows, Schildkraut says students are now broken up into smaller groups of four students to help reduce close exposure to one another during drills.She says those groups also practice the drills on different days to keep things efficient.Schildkraut and McDonald agree that since the pandemic, the drills focus on threat assessment. In day-to-day school functions, COVID-19 is the primary threat to student safety, so social-distancing rules are implemented even during drills. But if an emergency arises, they say that becomes the more imminent threat so that will be treated as the priority, even if it means social distancing cannot be followed.“If we have to go into a lockdown while we’re in school, even in the COVID world, we’re going to go into lockdown because that’s the threat that’s in front of us in that moment in time,” said McDonald. 3167

This is a battle that could shutter some classrooms indefinitely.Hundreds of Oklahoma teachers filled the state Capitol for a second day Tuesday, demanding an additional 0 million in school funding and increased raises for themselves and support staff.Their walkout comes days after the state approved some raises and school funding -- but only a fraction of what the teachers' union demanded.So despite school cancellations and even the risk of discipline from some districts, teachers say they won't budge."We will hold the line until hell freezes over, and then we will be here on ice skates," Muskogee High School teacher Diane Walker said. "We love our kids." 675

Tis’ the season to light up the night.In a downtown Denver high-rise apartment building, people are letting their Christmas spirit shine by decorating their balconies.“At least we can light it up and make people smile,” said resident Kim Dozier.Out West in Southern California, an Orange County neighborhood is celebrating the holidays by covering their houses and stringing lights across their street.“We see kids and families coming out here every night,” said homeowner Bruce Barfell.Across the country in New Jersey, the holiday spirit glows as people cover their houses with festive décor.And in San Antonio, Texas, there’s a battle to see who’s the biggest and brightest.These are some of the competitive Christmas lighting celebrations happening during this holiday season.“It’s a light beaming from all of us,” Dozier said of her building’s competition, adding it’s bringing some much-needed light to what’s been a dark 2020 for some.“It’s about showing the world we’re still alive,” she said. “Just because we have this insane time to stay at home and we’re going to have fun no matter what.”From the Mile High City to the California coast, spreading holiday cheer has been a bit more challenging during the COVID-19 crisis.“This year, unlike other years, it’s harder to kind of fill that Christmas spirit,” said Matt Eyre of Laguna Niguel.He and neighbor Barfell are looking to help people temporarily escape the pandemic through dazzling displays of lights.Though Barfell is looking to capture his neighborhood’s Christmas lighting competition for the tenth year in a row, he says whether win or lose, naughty or nice, it’s good to see little holiday magic.“We just do it for the enjoyment we get and also for what, you know, what people tell us when we’re outside,” Barfell said. “How much they appreciate this.”Spreading Christmas cheer through some friendly competition.“Competitive Christmas e lights is just another way to shine the love around everywhere,” Dozier said. “We’ve been held down for so many reasons for so long. So, Christmas, just lets you know just let it shine.” 2103

There’s a new trend online, and it’s making people money. But shoppers don’t even know what they’re purchasing.They’re called “Mystery Boxes” and the products are popular on sites like Etsy and eBay."We order stuff on Amazon all the time, but we know what we're getting, says Aurelia Seward, a seller on Etsy.“How much funner would it be to get a box and not know what’s inside of it?”  Seward sells all-natural holistic items and has been curating mystery boxes for about a month."My mystery boxes can be any array of items to handcrafted jewelry to real gem stones for healing,” she explains. “Lava stone bracelets for diffuser oils, essential oils, stuff like that."  Buyers can choose from all sorts of themed boxes, including electronics, toys, beauty products, etc.Seward’s boxes sell for .   "I haven't been doing too much marketing for them, but the orders are rolling in, so that's kind of fun.Some boxes can go for 0, but Seward cautions buyers to watch out for the more expensive ones."I've seen some that are really big duds,” she says. “Like, they have gotten dirty clothes.”Buyers should also check the seller’s reviews before purchasing a mystery box. 1200

Trade war fears and a presidential attack on Amazon are rocking Wall Street.The Dow dropped more than 700 points on Monday, and the Nasdaq plunged 3%. The S&P 500 hit its low for the year and was on track for its lowest close since November. The sell-off left all three major indexes in the red for 2018.By the end of the day Monday, the Dow slightly recovered, closing down 458 points for the day.The sell-off on the first day of the second quarter came after President Trump once again attacked Amazon on Twitter. Amazon, one of the biggest drivers of the 2017 market rally, tumbled 5%, wiping out more than billion of its market value.Trump once again accused Amazon of taking advantage of the US Postal Service, and he suggested that Amazon does not pay its fair share of tax.In fact, Amazon pays the same lower rate that the post office charges other bulk shippers, and it collects sales tax in every state that charges it. Amazon does not collect sales tax on purchases made from third-party vendors."You've got the president of the United States attacking a single company over what he considers to be unfair practices," said Ian Winer, head of equities at Wedbush Securities.Amazon wasn't the only tech stock in trouble. Tesla, Netflix and Cisco all dropped by at least 4%. Intel plunged 8% on a?Bloomberg News report that Apple plans to switch to its own chips. Almost every stock in the Nasdaq 100 lost ground.The Nasdaq has plunged more than 10% from its all-time high on March 12."When investors see market leaders suddenly stumble, they become more cautious about the entire group," said Kate Warne, investment strategist at Edward Jones.Wall Street is also fretting about rising trade tensions, especially with China. Beijing responded to Trump's steel and aluminum tariffs on Monday by following through on its threat to impose tariffs on billion of US imports. The tariffs apply to 128 products, ranging from pork and meat to steel pipes.Trump plans to place additional tariffs on about billion worth of Chinese goods — and Beijing has promised to respond.John Toohey, head of equities at USAA, blamed the sell-off on concerns about the China tariffs. "Global trade could slow down, global supply chains could be impacted, and CEOs could be more cautious on capital spending," Toohey said.NAFTA worries are also on the rise after Trump took aim at the trade deal between the United States, Canada and Mexico. Trump on Sunday linked NAFTA to his efforts to build a wall along the border with Mexico."They must stop the big drug and people flows, or I will stop their cash cow, NAFTA. NEED WALL!" Trump tweeted."It's a cause for concern. That mixing of issues is contributing to uncertainty," said Kristina Hooper, chief global market strategist at Invesco.No matter the cause, signs of fear abounded. The VIX volatility index jumped more than 15%. CNNMoney's Fear & Greed Index of market sentiment dropped further into "extreme fear." Crude oil plunged about 3%. Gold, which tends to do well when investors are worried, climbed more than 1%."None of it makes a lot of sense," said Michael Block, chief strategist at Rhino Trading Partners. "I don't know what we learned that was new. Chinese tariffs are not surprising."After spiking last year, the stock market hit extreme turbulence during the first three months of the year as investors worried about tariffs, inflation and tech stocks. The Dow snapped its longest quarterly winning streak in 20 years.Stocks may be volatile, but the backdrop looks bright. Global economic growth is expected to accelerate and corporate profits are likely to surge, thanks in part to Trump's corporate tax cuts."It's unlikely to be the end of the bull market," Warne said. "The underlying fundamentals remain positive." 3823
