PARKLAND, Florida — As students at Marjory Stoneman Douglas High School return from spring break, they will face several new security changes at the school.On Monday, students will receive clear backpacks for free, and the superintendent says those will be the only backpacks allowed on campus.The thousands of students at the school will also now wear a school identification badge everywhere on campus.This comes after the deadly school shooting in February that killed 17 people, but also after a series of incidents the week leading up to spring break.Two students were charged with bringing weapons on campus, and a third made a threat on social media.Deputies also arrested the confessed shooter’s brother for trespassing on the school property. Zachary Cruz pleaded no contest Thursday and sentenced to time served and six months of probation.A Broward County sheriff’s deputy was also suspended for allegedly sleeping in his patrol car while on duty at the school.Florida Highway Patrol will also have eight troopers stationed at the school entrances. The Broward County School district is providing additional security as well.This district will also consider metal detectors, metal detector wands, and trying to consolidate the point of entry for students and staff.The memorial that honored their classmates for the past six weeks is no longer there. Over spring break, it was cleaned up and moved so the items can be preserved. 1457

People are planning to take time off to travel through the end of the year, but of course, things look different because of the pandemic.“It’s not just as easy as it used to be to get in the car and go where you are going and have a great time,” said Jeanette Casselano McGee, a AAA spokesperson.First off, AAA says people will likely plan last minute. One in five travelers plan to book something only a week out, because people don't have a lot of confidence that they will be able to take the trip, because of how quickly things change with the virus.Most of these vacations will be road trips and to places that offer a lot of outdoors attractions.“Even if you are going to a national park, call ahead. Sometimes you need reservations or not everything may be open,” said McGee.It's also a good idea to check with hotels and restaurants in the area on capacity, as well as local and state virus restrictions.And there's promising new data for those planning to fly. The Department of Defense commissioned a 6-month long study using a United aircraft to learn more about the risk of COVID-19 exposure while flying.Mannequins were used to simulate coughing with a mask on and off. Sensors were placed in seats all over the plane to detect particles.It found after 300 tests both in the air and on the ground that when someone is wearing a mask, only .003% of particles made their way into another passenger's breathing zone, virtually 0%. Almost all particles are filtered out of the plane's cabin within 6 minutes.Last week, separate research by the International Air Transport Association found 44 published cases of potential in-flight transmission. Most happened in the early days of the pandemic when masks were not required. 1740

People in Idaho are walking through their future homes before the walls go up. "It's like you're really there cooking in your kitchen walking to the fridge back to the sink," said the owner of Draftech Brendan Smythe. Incorporating virtual reality into the mix can mean big bucks saved for homebuyers. There's a big demand in Idaho's Treasure Valley home market. According to data, nearly a quarter of sales are of new homes, and the cost of land and construction is rising. Some builders say nearly ,000-30,000 can be saved by making changes before the fieldwork begins."The changes and modifications they know they would've made out in the field they can make them a lot sooner, earlier on, more cost-effective up front," Smythe said. Draftech is an architecture design firm in the Treasure Valley taking their 2D drawings and blueprints and bringing them to life."You have your husband or your wife right next to you in the kitchen you get a sense of size and space," said Smythe. VR also helps all hands on deck save money and time."It saves all parties time because when you're making those changes to real estate properties or buildings while they're being built that can extend your timeline, so it can be extremely costly," said Annie Morley, the president of the Idaho Virtual Reality Council.Interior designers are also included in the VR equation so that clients can make change to surfaces and colors of their floors and cabinets inside their home with local materials readily available."In a few years I guarantee there won't be a single home designed without virtual reality," Smythe said.  1680

Police in Washington, D.C. released body camera video Thursday from the shooting death of 18-year-old Deon Kay.Police said the incident began Wednesday when Kay and his friends brandished firearms on a social media livestream. Officers located where the livestream was taking place, drove to the scene and found the group.Less than 10 seconds after arriving on the scene, Officer Alexander Alvarez fired the fatal shots that killed Kay.According to D.C. Metropolitan Police Chief Peter Newsham, Alvarez was chasing another suspect at the time of the shooting."When he turned around, that's when Deon Kay approached him and displayed a handgun, and in response to that, the officer fired one round," Newsham said. "Unfortunately, Deon Kay lost his life."Alavarez had been with the department for two years prior to the shooting. All officers involved in the shooting were placed on administrative leave, which is department policy.Police also said that Kay threw his gun away prior to being shot. Officers found it 90 feet away from his body."I know that he's validated gang member from the area and I know that he's had multiple touches with the criminal justice system," Newsham saod. "I'm pretty sure Deon Kay fell through multiple safety nets before yesterday afternoon."Washington, D.C. Mayor Muriel Bowser said the release of body cam footage doesn't answer all questions in the case, but added that it's a start."When we purchased these body-worn cameras, we knew that they wouldn't answer all the questions, for any incident, but they would tell us you know in some part what the officer or what the public saw at that time," Bowser said. 1653

Over the course of four hours on Tuesday, 175,000 Starbucks employees talked about racial bias.Across the country, employees participated in a mandatory training. About 8,000 company-owned stores and offices were closed to customers for the afternoon.In self-guided groups of three to five, workers settled in for an intense afternoon.Groups moved at their own pace, but their discussions followed a similar structure. With the help of guidebooks distributed throughout the stores, workers took part in sensitive conversations. They watched videos featuring Starbucks executives and musician and activist Common.They reflected by themselves, in pairs and as a group, on the meaning of bias. They privately jotted down thoughts in a customized notebook outfitted with prompts about identity and race. They ran through scenarios that may elicit a biased reaction. They practiced welcoming behaviors, and committed to changing their habits for the better. 960
