Arming teachers may be a "terrible" or even a "ridiculous" idea to critics, but some teachers across the country already bring guns to school.In the wake of the Florida school shooting, the debate over whether teachers should carry guns in class has intensified. President Donald Trump is proposing bonuses for educators who undergo gun training. State lawmakers are beginning to consider legislation while school officials are pushing for an increase in classroom resources but not guns.State laws related to guns in schools vary by state and although many only apply to college campuses, some states give teachers with concealed carry permits the ability to have guns on the grounds of K-12 schools, according to the Giffords Law Center to Prevent Gun Violence.Here's a look at some of the states where teachers and other school staff are willing to carry their weapons.  886

As a third-grade elementary school teacher, Reed Clapp never imagined he would be finishing the school year sitting inside the living room of his home. But the COVID-19 outbreak had other plans for this teacher and so many others across the country.Undeterred by a nationwide pandemic, Clapp was determined to finish out this school year the same as any other: with a play that he and fellow teacher, Karen Snyder, have produced for the last five years.“This is one of the most challenging things I’ve ever taken on,” he said, sitting inside the living room of his home in Nashville, Tennessee.The name of the show Clapp and his class would perform in years past was called, “Grammarella,” a satirical production of Cinderella, where every student plays a part of speech. The character Interrogative, for example, can only speak in questions.On the last day of every school year, Clapp’s students would perform the play in front of their classmates at Madison Creek Elementary School in Hendersonville, Tennessee. It’s become such a hit over the years that there’s typically not an empty seat in the school’s library on opening afternoon, which is also closing night. There’s only one showing.But how could Clapp, harness that same kind of magic without his kids physically at school?After a few weeks of thinking, he decided the answer to that question was right in front of him: he’d move the play to Zoom, a virtual video platform.“Instead of saying, ‘we won’t have a play this year,’ we decided to say, ‘how can we do something that is original and something these kids are proud of?” he said.As summer vacation loomed, Clapp and his third-graders began to double down on their work. This energetic 33-year-old teacher with a thick southern drawl knew the script for “Grammarella” would have to be thrown out. So, he started from scratch and came up with an original screenplay, “Zoomarella.”Students auditioned for lead roles on Zoom, and they even practiced social distancing by picking up costumes that Mr. Clapp and Ms. Snyder had left outside on their front porches.Over the course of a few weeks, the play started coming together. Eight and 9-year-old students learned how to be punctual for rehearsal times, that instead of being held in the classroom, they were being held on Zoom. While Clapp’s original intent was to help students learn grammar, he quickly released that “Zoomarella” was teaching his students more important life skills.“Yes, they’re 8 years old, but when we say, ‘we need some light behind you,’ what we’re really saying is, ‘what can you do to put a light behind you?’” he explained.“These kids have become set designers, light designers, camera operators. It’s amazing,” he added.And for students facing isolation at home, rehearsals offered a sense of a vehicle for creativity that might have otherwise been lost when the school closed.“The stuff that has been the hardest is getting facial expressions and acting with your body. You have to use your body and facial expressions and not just when it’s your turn to talk,” explained 9-year-old Autumn Fair.Weeks of practicing finally paid off for Fair and her classmates, as “Zoomarella” was performed without a hitch during the last week of school. And even though the kids might not have been able to hear the applause through their Zoom meeting, Clapp says he couldn’t have been prouder of his kids.“I hope they take away a moment in time that’s been captured in a unique way. Instead of looking back on all this through news stories, they’ll have this play to look back on,” the proud teacher said.Watch “Zoomarella” below: 3619

An American woman and a Japanese man won the elite divisions in the Boston Marathon Monday, the first time runners from each country have taken the top spots in more than 30 years.Desiree (Desi) Linden, a two-time Olympian, battled the rain and wind to win the 122nd running of the storied race. It's also the first marathon win of the 34-year-old's career."I love this city," Linden said. "I love this race, this course. It's storybook, so I'm thrilled to be here and to get it done."And Yuki Kawauchi of Japan came in first place in the men's elite division, overtaking Geoffrey Kirui of Kenya in the final miles. American Shadrack Biwott was third."For me, these are the best conditions possible," Kawauchi said, according to the Boston Marathon's Twitter account.For the fourth year in a row, Marcel Hug of Switzerland won the men's push rim wheelchair division, while American Tatyana McFadden won the women's push rim wheelchair division for the fifth time.In 2011, Linden finished second in the women's division, just 2 seconds behind Caroline Kilel. She also was second at the US Olympic Marathon trials in 2012. Linden finished fourth in the Boston Marathon last year.Earlier in the race, Linden temporarily took herself out of contention to help fellow American Shalane Flanagan. Flanagan dropped out of the lead pack to go to a portable toilet. Showing tremendous sportsmanship, Linden hung back to wait for Flanagan so they could both return to the lead pack together."Honestly, at mile 2, 3, 4 I didn't feel like I was even going to make it to the finish line," Linden said. "I told her in the race, I said, 'You know, if there's anything I can do to help you out, let me know because I might just drop out. When you work together, you never know what's going to happen. Helping her helped me and kind of got my legs back from there."Flanagan finished sixth, one of six American women finishing in the top eight.Before Linden, the last American woman to win the Boston Marathon was Lisa Rainsberger in 1985.The last Japanese man to win the famous race was Toshihiko Seko in 1987. The last American man to win Boston was Meb Keflezighi, in 2014.  2171

Mail sent to the White House is screened off site before reaching the complex.According to the CDC, Ricin is a poison found naturally in castor beans.“If made into a partially purified material or refined into a terrorist or warfare agent, ricin could be used to expose people through the air, food, or water,” the CDC said, adding that there is no known antidote for ricin.The White House has been the target of ricin mailings in the past.
