An Alabama family is mourning a man killed by police Thanksgiving night after being mistaken for the shooter who injured two people at a mall.An officer fatally shot Emantic Fitzgerald Bradford Jr. about 10 p.m. CT Thursday at the Riverchase Galleria in Hoover, a Birmingham suburb. At the time, authorities said he got into an altercation at the mall and opened fire, injuring two people ages 18 and 12.An officer encountered an armed Bradford fleeing the scene and fatally shot him, police said.But after conducting forensic tests and talking to witnesses, investigators said Bradford might have been involved in the altercation but likely did not fire the rounds that injured the two youths.The gunman is still at large and police have not provided a name or description.Relatives are demanding answers as they mourn a man they call EJ."EJ was a devoted son and brother, who dedicated his life to serving his country and always doing the right thing," his family said in a statement."As we continue to grieve, rest assured that we are working diligently with our legal team to determine exactly what happened and why this police officer killed our son. We will never forget EJ, and ask for your continued prayers during this incredibly difficult time.""They killed him for no reason at all. He wasn't the shooter," his aunt, Catherine Jewell, told reporters. "He was a great guy. He was very respectable ... They did him wrong."Bradford's Facebook page says he was a US Army engineer. But he did not complete advanced individual training and did not serve, said Lt. Col. Manny Ortiz, an Army spokesman.The Bradford family has retained civil rights attorney Benjamin L. Crump, according to a statement from the law firm.Crump previously represented the family of Trayvon Martin, a 17-year-old African-American fatally shot in Florida in 2012. 1852

An independent news organization has researched reports regarding the size of airplane seating, and its findings led it to call coach-class seating a "death trap."The Daily Beast says dense, shrunken seat space does not do a safe enough job of allowing passengers to move quickly in the event of emergencies. DB's investigation found the FAA nor Boeing is disclosing evacuation test data "for the newest (and most densely seated) versions of the most widely used jet, the Boeing 737."It also found tests to ensure all passengers may safely leave a cabin are "dangerously outdated." They do not reflect how densely packed coach class seating has become, the report says."No coach class seat meets the Department of Transportation's own standard for space required to make a flight attendant's seat safe in an emergency," the DB reports. And a judge in a case brought by the Flyers Rights activist organization said there is "plausible life-and-death safety concern" about the "densification" of coach seating.The Daily Beast's report says that court "complained that the FAA had used outdated studies to argue that no change was needed" for how tests are performed, and it refused to release results of tests.The DB looked at 900 pages of Department of Transportation documents; go here to see its full report. 1327

As coronavirus cases reached a new high on Friday in the US, Dr. Anthony Fauci now believes a mask mandate is necessary to stop the spread of the virus.But Dr. Fauci acknowledges enforcing a mask mandate is a challenge. Adding to the challenge, officials in recent days say that family gatherings are becoming a significant reason why cases are growing throughout the US.“I think that would be a great idea to have everybody do it uniformly,” Fauci said in an interview on CNN on Friday. “And one of the issues though, I get the argument say, 'Well, if you mandate a mask, then you're going to have to enforce it and that'll create more of a problem.' Well, if people are not wearing masks, then maybe we should be mandating it."The University of Washington’s Institute for Health Metrics and Evaluation projects that near universal mask wearing outside of the household would save anywhere from 60,000 to 160,000 lives in the US between now and February 1.While many public institutions, such as grocery stores, restaurants, and other facilities have implemented mask and social distancing policies to help slow the virus, public health officials say smaller, more interment gatherings, are where many are letting their guard down.With colder weather setting in and major holidays upcoming, public health officials are becoming increasingly concerned as cases increase throughout much of the US.“Smaller more intimate gatherings of family, friends and neighbors may be driving infection as well especially as these gatherings move indoors and adherence to face coverings and social distancing may not be optimal,” said Dr. Jay Butler, deputy director of infectious diseases at the CDC. “I recognize that we are all getting tired of the impact that COVID-19 has had on our lives. We get tired of wearing masks but it continues to be as important as it’s ever been and I would say it’s more important than ever as we move into the fall season.”Health and Human Service Secretary Alex Azar agrees with Dr. Butler’s assessment.“We’ve got to keep focused on washing our hands, watching our distance and wearing our face coverings when we can't watch our distance and in particular being careful in household gatherings. This has become a major vector of disease spread,” Azar told CNN’s Jim Sciutto. 2303

Anyone who plans to travel internationally should get tested for COVID-19 before and after their trip, according to new Centers for Disease Control and Prevention (CDC) recommendations.In addition, the CDC says anyone returning from international travel should isolate for at least seven days — even if they test negative for COVID-19 upon their return.Planning aheadIn the new guidance published to its website, the CDC recommends travelers plan ahead several weeks before travel. The CDC says to avoid high-risk activities like large social gatherings (parties, weddings, funerals, sporting events), indoor recreation (bars, restaurants, fitness centers) and taking public transportation for at least two weeks.As the travel date approaches, the CDC recommends receiving a test between one and three days before boarding an international flight — but also to make sure test results are available before the flight departs. If the test results aren't back in time, the CDC recommends delaying travel.The CDC stresses that anyone who tests positive for COVID-19 should not travel — anyone who tests positive should immediately isolate and follow public health recommendations.The CDC also says that anyone who tests negative should still wear a mask, maintain 6 feet of social distance and wash hands frequently while traveling."A negative test does not mean that you were not exposed or that you will not develop COVID-19," the CDC says on its website.Finally, travelers should carry a copy of their test results with them — officials in other countries may ask to see them.Upon ReturnUpon return to the U.S., travelers should get another COVID-19 test within three to five days upon return. Even if that test comes back negative, the CDC urges a full week of self-isolation."You may have been exposed to COVID-19 on your travels. You may feel well and not have any symptoms, but you can be contagious without symptoms and spread the virus to others. You and your travel companions (including children) pose a risk to your family, friends, and community for 14 days after you were exposed to the virus," the CDC writes on its website.Anyone who chooses not to get tested upon their return to the U.S. should stay home for 14 days.Places where it's safe to travelThe CDC's website also includes risk assessment maps to help travelers determine where COVID-19 is spreading. As of Wednesday morning, nearly every country around the world was listed as a Level 4 risk — the highest level listed by the CDC.Click here to see the CDC's risk assessment map. 2559
