This year, the number of school shootings in the United States has dropped tremendously because of the pandemic.According to the Center for Homeland Defense and Security, there has only been one shooting inside a school building since March; an accidental discharge of a firearm inside North Forney High School in Forney, Texas that happened before pandemic shutdowns began.It may be one silver lining in a year many wish to forget.But just because numbers are down, does not mean schools are not still prioritizing active shooter drills.According to Everytown for Gun Safety, a public advocacy group, 95 percent of K-12 schools implement active shooter drills, but the number can vary by state. For instance, in New York State, schools are required to have four lockdown drills per year, whereas in New Jersey the requirement is two.Since the pandemic started, most states have required those same number of drills despite some students choosing to learn from home, in-person restrictions, and social distancing.“We had to redesign the entire drill,” said John McDonald, executive director of security and emergency management at JeffCo Public Schools in Colorado. “We had to redesign what it looked like. How do you socially distance when you’re locking down?”McDonald laid the blueprint for school safety across the country when he was brought in by the JeffCo Public School District to implement new safety measures after the Columbine School Shooting in 1999.In the COVID-19 world, students in his school district are now learning about active shooter drills through a three-minute video presentation he helped design.“We have kids learning [these active shooter lessons] since kindergarten,” said McDonald. “So, this helps supplement that and reinforce that muscle memory.”In the Syracuse School District in New York, however, the drills are a little different than in Colorado.“I think that there’s always a need to balance the safety of the potentially very worst day with the challenges of safety and student well-being that schools face every single day,” said Jaclyn Schildkraut, a criminal justice professor at SUNY-Oswego.Schildkraut helped the Syracuse school district redesign its plans following COVID-19. Instead of the normal drills, where a full class might huddle together out of sight of windows, Schildkraut says students are now broken up into smaller groups of four students to help reduce close exposure to one another during drills.She says those groups also practice the drills on different days to keep things efficient.Schildkraut and McDonald agree that since the pandemic, the drills focus on threat assessment. In day-to-day school functions, COVID-19 is the primary threat to student safety, so social-distancing rules are implemented even during drills. But if an emergency arises, they say that becomes the more imminent threat so that will be treated as the priority, even if it means social distancing cannot be followed.“If we have to go into a lockdown while we’re in school, even in the COVID world, we’re going to go into lockdown because that’s the threat that’s in front of us in that moment in time,” said McDonald. 3167

There is a web of connections between the Trump campaign, the anti-secrecy website WikiLeaks and the public disclosures it injected into the presidential campaign. Federal investigators are examining some of these relationships and whether any of them were part of an effort to coordinate with Russia's election-meddling efforts.On Monday, it was revealed that Donald Trump Jr. exchanged some private messages on Twitter with WikiLeaks during the 2016 presidential campaign. The news was first reported by The Atlantic and later confirmed by Trump Jr., who posted screenshots of the messages.A source familiar with the matter told CNN that Congress has known about these messages for a while and they came up during Trump Jr.'s closed-door testimony in September. 771

The YouTube headquarters where a female shooter wounded three people before apparently taking her own life has more than 1,100 workers and is located in San Bruno, about 13 miles south of San Francisco.Employees there include engineers working on site search, content channels and ad products, according to a website of Google, YouTube's parent company. The workforce also includes sales teams that work with advertisers and content creators who develop programming, the Google website says."An open, airy space makes collaboration a breeze and encourages innovation," the website says in describing the headquarters, which includes a basketball court and a lap pool.YouTube, which was founded in February 2005, quickly became the most well-known of several online video sites. In October 2006 Google said it was purchasing YouTube for .65 billion in stock. 877

There was briefly another participant swooping into Wednesday night’s vice presidential debate.For several minutes, a fly landed in Vice President Mike Pence’s hair, not moving as he answered questions about racial injustice and whether justice has been done in the death of Breonna Taylor.Conversation about the fly briefly dominated corners of Twitter, where debate watchers discussed their distraction and inability to focus on Pence and California Sen. Kamala Harris’ answers. Some joked about the need to test the fly for the coronavirus, as it had skirted the plexiglass partitions separating the candidates and moderator.Wednesday night’s intruder wasn’t the first to take center stage at an election year debate. In 2016, a fly briefly landed between Democratic nominee Hillary Clinton’s eyes during a town hall-style debate with now-President Donald Trump.The Biden campaign used the fly incident as a fundraising opportunity: 944

There's some misunderstanding about medical exemptions to wearing masks.A legal expert tells us the Americans with Disabilities Act (ADA) makes it so businesses must make reasonable accommodations to everyone. The key word there is reasonable.“The problem with what's going on right now and some of the things that have been going around the internet, is that the advice, kind of spurious advice that's being put forth is to use the provision for reasonable accommodation as a sword rather than as a shield,” said David Tarrien, an associate professor at WMU-Cooley Law School.Tarrien says the conditions that qualify as a mask exemption have a smaller scope than many realize. For example, he says asthma patients likely do not fall under that scope. But later stages of pulmonary respiratory disease, emphysema, or a serious mobility issue can be "legitimate" reasons.Furthermore, you could face repercussions for lying.“If they're claiming that they have a disability and they don't have a disability, if that is found out, then there are criminal and civil penalties for that,” said Tarrien.As for privacy concerns, Tarrien says store employees are allowed to ask customers why they're not wearing a mask. If you refuse to answer, they may refuse entry.Even if you give a legitimate reason to not wear a mask, you may still be refused entry. That's because the ADA does not apply if there's a “direct threat” to someone's health or safety.Tarrien says HIPPA privacy laws also do not apply in this kind of situation. That only protects your information from being shared inappropriately among medical facilities. 1623
