TAMPA, Fla. -- As parents across the country grow more concerned every morning when they send their kids to school, more and more are turning to bulletproof backpacks.“After Sandy Hook, people couldn’t wrap their minds around a bulletproof backpack but now they think it’s something that they need," said Yasir Sheikh, the president of Guard Dog Security.The Sandy Hook shooting inspired Sheikh to create a backpack out of bulletproof materials. It doesn’t seem like much. The backpack has just a thin layer of kevlar, but it is certified to withstand handgun rounds.“Ideally, we think with the way things are going this should become mandatory, common for all students," said Skeikh. "It’s a sad reality, it’s become a new normal."Others feel the same. Just three days after the deadly school shooting in South Florida his company saw a 150 percent increase in the number of bags they shipped.But do they actually work?Ryan Hart is a certified firearm instructor for defense training company Ground Ready International Training, or G.R.I.T Ready. He also teaches active shooter survival courses.Hart put a barrel with sand behind the backpack to simulate a body and took aim with his Glock 19.“The rounds definitely penetrated the front of the bag here," said Hart inspecting the shot-up bag, "But if we flip it over there’s no penetration past the armor itself."Next up: the AR-15.In the last decade, this style of gun has been used in six of the 10 deadliest mass shootings throughout the country, including the Parkland school shooting.“It went right through the soft armor," Hart said after spraying the backpack with bullets from the AR-15.It's what Hart expected, as the Guard Dog Security backpack is not certified to withstand assault-style weapons. To stop bullets from a similar weapon, the backpack would need to be equipped with steel plates like those installed in military vests. However, that would make the backpack fairly heavy to carry.“I would recommend (the backpack), yes," Hart said. "While it did not stop a direct shot from an assault rifle it can still stop bullet fragments, ricochets, glass flying through the air.”Then we posed this question to Skeikh: "What do you think it says about our society that we are resorting to items like this?"The backpacks cost between 0-200. Fifty percent of the proceeds from sales of the backpacks right now will go to the victim's families of the Parkland shooting.Guard Dog Security is also looking into possibly making backpack, that would have the ability to stop assault-style weapons. 2664

Texas health officials say new cases of the coronavirus that causes COVID-19 have hit a new peak. According to the Johns Hopkins website, the state recorded 1,010,364 cases early Wednesday with 19,337 deaths since the pandemic began in early March.Texas recorded 10,865 coronavirus cases on Tuesday, setting a new daily record that surpassed by 74 cases an old mark set July 15, state officials said.According to state figures on Tuesday, an estimated 132,146 cases are active, the most since Aug. 17, and 6,170 COVID-19 cases are hospitalized, the most since Aug. 18.The true number of infections is likely higher because many people haven’t been tested, and studies suggest people can be infected and not feel sick.There were 94 new deaths Tuesday, according to the Texas Department of State Health Services.Meanwhile, cases of the coronavirus that causes COVID-19 are surging in the Laredo area as the borderlands remained a COVID-19 hotbed Tuesday, health officials said.Laredo health officials reported 331 new cases Tuesday of the coronavirus, the most since the Aug. 10 peak of 374 cases. That brought the area’s case count for the pandemic since the beginning of March to 16,558. Of those, 934 cases are active, the most in two months, and 73 require hospitalization. One new death was reported Tuesday, bringing the city’s COVID-19 death toll to 367.The surge comes as El Paso, another border city, grapples with a recent tsunami of cases. Another 1,292 cases were reported in El Paso County on Tuesday, bringing its pandemic count to 65,651 with 27,895 cases now active and 1,076 requiring hospitalization. Nine new deaths brought the county’s COVID-19 death toll to 682.The higher counts come amid intensive testing in both places and statewide.For most people, the coronavirus causes mild or moderate symptoms, such as fever and a cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death. 2034

Tap your heels together three times, and you’ll be home.Those were the instructions from Glinda the Good Witch gave to Judy Garland in the 1939 classic The Wizard of Oz.But today, the idea of tapping those ruby slippers together is enough to make conservator Dawn Wallace cringe.“I spent probably over 200 hours just working on the sequins themselves,” says Wallace. “So, I take great care.”Wallace is an objects conservator at the Smithsonian. She’s charged with caring for the famous ruby slippers worn by Garland in the movie.“Every single time I pick up these shoes, they are an American treasure and they are iconic,” says Wallace. “I always feel excited, and I always get a little bit of a thrill knowing that I get to work with these amazing objects.”It’s been a painstaking nearly two-year conservation process, cleaning every bead and realigning every sequin.“The sequins on the toes, they were exposed to light during the filming,” explains Wallace. “So, those have more light damage. So, we do see some fading on some of those sequins.”Wallace also points out there are some beads missing from the shoes, but says it’s, “part of their story.”Wallace cares for all parts of the shoe, right down to the felt soles. She explains the slippers were lined with felt so they make minimal noise during dancing scenes. It’s those scenes that generations of fans, including Wallace, remember vividly.“I think everyone always gets up they click their heels, and they get with their friends and family and they skip arm in arm.,” says Wallace. “And so, I think it—it hits you.”As they return to public display today, they’re doing so amid renewed interest, thanks to the FBI’s announcement last month that they found another pair used in filming. That pair was stolen 13 years ago.In fact, the agency even asked Wallace, who is now an authority on the chemical makeup of the shoes, to examine the recovered pair. She says she felt like a character from another movie.“I almost wanna say it’s a little like Indiana Jones,” recalls Wallace. “It was very thrilling, but it also made me feel very proud knowing I’m helping return these stolen items.”Wallace says she was worried about what the slippers would look like after being stolen over a decade ago, but she says they were recovered in similar condition to the other pair.“Just using a little bit of water and small cotton swabs, being able to remove that dirt just really brought the shine back to the beads,” Wallace says of the restoration process.After a couple of years out of public view, the slippers will now be back on display for fans to see. 2622

Survivors of the 2016 Pulse nightclub shooting are opening old wounds to seek justice as the trial of the gunman's widow opens in Orlando.Jury selection begins Thursday in the federal trial of Noor Salman, who is charged with providing material support to a foreign terrorist organization and obstruction of justice for allegedly misleading law enforcement agents investigating the massacre on June 12, 2016.Salman has pleaded not guilty to all the charges. If convicted, she could face life in prison.Prosecutors believe Salman was aware of her husband's plans and will argue that she could have tipped off authorities to prevent the mass shooting at the gay nightclub, which left 49 people dead and more than 50 others wounded.Salman's attorneys will claim that their client had no prior knowledge about Omar Mateen's plans and that she was a wife enduring her husband's abuse. One of her attorneys has said that Salman suffers post-traumatic stress disorder due to years of physical and mental abuse, CNN affiliate WKMG reported. Selecting a fair jury 1067

The attorney for the porn star who claims to have slept with Donald Trump told CNN's "New Day" on Monday to expect more evidence that suggests Trump knew about the hush agreement his client now argues is invalid.Michael Avenatti, the attorney for Stormy Daniels, said new evidence will likely be brought forward "over the next few weeks and months" that will help prove Trump was aware of a 0,000 hush agreement drawn up by Trump's personal lawyer, Michael Cohen, and executed just before the 2016 election."It is just the beginning," Avenatti said on "New Day." "We have a whole host of evidence. This is not going away. And Mr. Cohen better come clean for the American people, and they better do it quickly." 721
