According to AAA's annual projection released on Thursday, 55 million Americans are expected to travel this year for Thanksgiving, making it the busiest Thanksgiving for travel since 2005.AAA said it expects a 2.9 percent increase in traffic over the Thanksgiving holiday weekend from last year, which marks about 1.5 million additional travelers. Of the 55 million planning to travel more than 50 miles, 49.3 million will do so by automobile. For those planning on traveling the day before Thanksgiving, major delays are expected, especially in major metropolitan areas. “With record levels of travelers, and persistent population growth in the country’s major metropolitan areas, drivers must prepare for major delays,” said Trevor Reed, transportation analyst at INRIX. “Although travel times will peak on Wednesday afternoon nationally, travelers should expect much heavier than normal congestion throughout the week.”If traveling by plane, AAA recommends to travel the Monday before Thanksgiving to take advantage of lower rates. Part of the reason for an increase in travel is due to strong economic numbers, AAA claims. “Strong economic fundamentals are motivating Americans to venture out this holiday in near-record numbers. Consumer spending remains strong, thanks to increasing wages, disposable income and household wealth, and travel remains one of their top priorities for the holiday season," said Paula Twidale, vice president, AAA Travel. 1467

A World Health Organization funded study published this week in the Lancet found that masks, physical distancing and eye protection offer substantial reduction in the spread of COVID-19. The study cautioned that even when used effectively and in combination, none of the interventions will completely prevent the spread of the virus. But the study’s authors offer some optimism the virus can be significantly slowed sans a vaccine. Keeping a distance of 1 meter in both healthcare and community settings reduced the risk of infection by 82 percent, according the research authored by a group of six infectious disease experts. Every additional meter of separation more than doubled the relative protection. “This evidence is important to support community physical distancing guidelines and shows risk reduction is feasible by physical distancing,” the study said. “Moreover, this finding can inform lifting of societal restrictions and safer ways of gathering in the community.”The study found that infectious droplets can travel up to 8 feet, and can stay in the air for hours. The use of masks and respirators with those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.Dr. Derek Chu from McMaster University, and co-author of the study, found that the most effective homemade masks should be ones that are water-resistant, have multiple layers, and are a good facial fit. The study also suggests that wearing eye protection resulted in a 78% reduction in infection; infection via the ocular route might occur by aerosol transmission or self-inoculation the study said. This point was one the researchers had less confidence in, and further data is needed to draw a conclusion. To read the full study, click 1901

A subtle design feature of the AR-15 rifle has raised a technical legal question that is derailing cases against people who are charged with illegally buying and selling the gun’s parts or building the weapon.At issue is whether a key piece of one of America’s most popular firearms meets the definition of a gun that prosecutors have long relied on.For decades, the federal government has treated a mechanism called the lower receiver as the essential piece of the semiautomatic rifle, which has been used in some of the nation’s deadliest mass shootings. Prosecutors regularly bring charges based on that specific part.But some defense attorneys have recently argued that the part alone does not meet the definition in the law. Federal law enforcement officials, who have long been concerned about the discrepancy, are increasingly worried that it could hinder some criminal prosecutions and undermine firearms regulations nationwide.“Now the cat is out of the bag, so I think you’ll see more of this going on,” said Stephen Halbrook, an attorney who has written books on gun law and history. “Basically, the government has gotten away with this for a long time.”Cases involving lower receivers represent a small fraction of the thousands of federal gun charges filed each year. But the loophole has allowed some people accused of illegally selling or possessing the parts, including convicted felons, to escape prosecution. The issue also complicates efforts to address so-called ghost guns, which are largely untraceable because they are assembled from parts.Since 2016, at least five defendants have challenged the government and succeeded in getting some charges dropped, avoiding prison or seeing their cases dismissed entirely. Three judges have rejected the government’s interpretation of the law, despite dire warnings from prosecutors.Federal 1866

An armed man was fatally shot early Saturday during a confrontation with police after he hurled incendiary devices at a Washington state immigration detention center, Tacoma police said.The shooting occurred about 4 a.m. local time outside the US Immigration and Customs Enforcement's Northwest Detention Center, where the gunman attempted to set the building and parked cars on fire, according to police spokeswoman Loretta Cool.Authorities did not immediately identify the gunman, saying in the statement the "medical examiner will release the identity of the victim when it is appropriate."The assault on the privately-run immigrant detention facility came amid protests over ICE plans to begin the previously postponed raids across the country on Sunday. The goal is the arrest of thousands of migrant families who already have court orders to be removed, according to US officials.A peaceful rally against the raids at the Tacoma detention center had ended about six hours before the shooting, Cool said.The immigration enforcement action has sparked protests in nearly a dozen American cities, drawn criticism from mayors and immigrant rights advocates, and unleashed waves of fear among undocumented immigrants across the country.The motive behind the armed man's pre-dawn attack in unclear, Cool said.The Tacoma facility, which holds nearly 1,500 detainees, has been the scene of more than a dozen hunger strikes in recent years -- each involving from a dozen to hundreds of detainees, over complaints of inadequate food and medical care, among other issues. Police said the man set a vehicle ablaze in the center's parking lot and attempted to ignite a propane tank with a flare to set the building on fire. Officers called out to the man and shots were fired, according
