The massacre of 26 worshipers at a rural Texas church is the latest in a grisly series of mass shootings across America in recent years.With each tragedy, we hear arguments about gun violence, mental health, how much firearms should be regulated and what’s driving the prevalence of mass shootings. PolitiFact has worked for years to research these topics to help explain talking points used by all sides of the debate.Here are some answers to some questions you may have.How do we define mass shootings?There is no widely accepted definition of mass shootings. People use either broad or restrictive definitions of mass shootings to reinforce their stance on gun control.Researchers at the nonpartisan Congressional Research Service defined "mass shooting" as "a multiple homicide incident in which four or more victims are murdered with firearms, within one event, and in one or more locations in close proximity" in a 2015 report. They counted 317 mass shootings from 1999-2013.The report also used the term "mass public shooting" for a multiple homicide incident in which four or more victims are murdered with firearms, within one event, in at least one or more public locations, such as a workplace, school or house of worship. There were 66 attacks that met that definition during that 15-year period.After the 2012 Sandy Hook school shooting, Congress defined "mass killings" as three or more homicides in a single incident. The definition was intended to clarify when the U.S. Attorney General could assist state and local authorities in investigations of violent acts and shootings in places of public use.The Gun Violence Archive tracks gun deaths using media, law enforcement, government and commercial sources. Its data is based on a broader criteria: at least four people injured or killed in one location, not including the suspect. Criminologists previously told?PolitiFact that this group’s tally includes gang shootings and home invasion robberies.When is a mass shooting in the United States considered terrorism?A mass shooting needs to meet several criteria in order to be legally labeled as domestic terrorism. That definition applies to acts dangerous to human life that are a violation of U.S. or state criminal laws, which occur primarily within U.S. territorial jurisdiction and appear to be intended to: 2388

The major boom of online grocery ordering shows no signs of slowing down. More than six months into the COVID-19 pandemic, industry experts say the new convenience of ordering groceries through an app is here to stay. "In fact, it's been a huge acceleration. All of our clients that we serve, and we serve some of the biggest supermarkets in North America and the world, they picked up three times the volume that they were doing before this pandemic. And, in fact, more of them didn’t picked up more volume because they couldn't just fulfill enough orders at a time," said Max Pedro, the co-founder and president of Takeoff Technologies. Takeoff Technologies creates automated grocery fulfillment software for some of the biggest grocery chains in the country, including Albertsons, Safeway and Shoprite. The technology requires supermarkets to build a 10,000-square-foot warehouse directly behind their store. When a shopper places an online grocery order at one of these stores, the robots fulfill the order, automatically placing the items in bags, ready for the customer."What happens is those robots bring those individual items to a human being, but those items are coming to a person. They're suddenly making people 13 times more productive than if they have to roam a supermarket aisle to assemble that order," said Pedro.The company has already hit their five-year goal in just four months. "And it’s happened really fast and what’s also happening is we know that consumers are not going back to their previous behaviors. We forcefully trained many, many people to buy their supermarket carts online and they're sticking to it," said Pedro.Laurentia Romaniuk, an Instacart Trends Expert, agrees. "We've seen customers continue to use our site. It seems like online grocery is really here to stay. It's interesting because online grocery has existed in other countries for decades and people have built habits around it in other countries and I think, finally, now America is getting on board with the online grocery trend," said Romaniuk.Instacart, which offers grocery delivery service for a fee from a number of grocery stores across the country, says use of their site went up exponentially at the start of the pandemic. Now that we're in the fall, parents and children are still working and taking classes from home and the need to get groceries delivered or gathered for them, is still there. "Yes, customers are going online and shopping online and becoming more comfortable with that, but also hobbies and habits and eating patterns are changing," said Romaniuk.Pedro says pre-pandemic, only 10% of the market was buying online. It's now grown to 27%. "Remind you that four years ago, the U.S. market was half-a-percent online. Grocery is a really rough category to offer online and still maintain those low prices. Now, with these capabilities and that further need of getting the convenience factor, things have just taken off," said Pedro. Pedro suspects the entire retail industry will soon start reinventing itself, developing technology to offer more delivery and pick-up options to better serve customers who no longer want to go shopping in person. 3181

The latest sexual assault allegations against Harvey Weinstein could result in the first criminal charges against the movie mogul, an NYPD source familiar with the investigation told CNN."This is the strongest case we've had that fits within the statute of limitations," the source said, adding some detectives believe they have enough evidence to arrest Weinstein.At a press conference Friday, NYPD Chief of Detectives Bob Boyce described de la Huerta's case as credible because of her "ability to articulate each movement of the crime, where she was, where this happened." 582

The pizza chain Domino’s forked over ,000 to the city of Milwaukee to fill potholes. The move is part of an ad campaign the pizza maker is doing to help remove potholes that can ruin a pizza en route to your home. The Department of Public Works confirmed that they received the money from Domino’s to fill the potholes. 339

The National Rifle Association should move its annual convention from Dallas to somewhere else after last week's massacre at a Florida high school that left 17 students dead, a Dallas city official says.It's not appropriate for the group to meet in Dallas in May because there's so much gun violence in the United States, Dallas City Council Member Dwaine Caraway saidAssault rifles like the one used in the Florida school shooting should be outlawed, he said Monday at a news conference, and "the NRA needs to step up to the plate and they need to show leadership."CNN's calls to the NRA for comment were not immediately returned.Caraway, who is serving as mayor pro tem, meaning he fills in when the mayor is absent, said he's expressing a personal belief about the NRA and has not initiated any action in the city government to stop the convention.At a Monday news conference, Caraway said he had not spoken directly to any NRA officials."I am saying to the NRA, reconsider yourselves coming to Dallas," Caraway said. "There will be marches and demonstrations should they come to Dallas and we, Dallas, will be the ones that have to bear the cost and the responsibility and to protect the citizens."Caraway noted that gun violence has visited Dallas before, with the 1963 assassination of President John F. Kennedy and the 2016 slaying of five city police officers. Caraway said he owns five firearms himself but thinks assault rifles should only be available for the military and law enforcement."Who needs an AR-15 to go hunting?" he said. "Who needs an AR-15 to protect their house?"The NRA convention is scheduled to take place May 3-6 in the Kay Bailey Hutchison Convention Center in Dallas. This is the group's 147th annual meeting, according to the NRA website, which invites "over 80,000 patriots and 800+ exhibitors" to attend."Why the NRA now?" Caraway said. "Because it's their convention. It's because it's their responsibility. It's because they stand for the very things we are confronted with every day of our lives. Those kids in Florida, they will have to live with these nightmares the rest of their lives."In a Tuesday interview with CNN, Caraway said leaders should listen to those students."If those kids in Florida, for example, knew that something was being addressed then they wouldn't be staging protests," he said. "Those kids need to be at the table, and voicing their opinions. The NRA needs to open their ears and hear what is it we need to strengthen, what it is we need to limit, and then everyone comes out happier and safer."Dallas Mayor Mike Rawlings issued a statement saying he disagreed with the NRA's viewpoint and tactics, but "they have a legal contract that was signed in 2012 and I'm not advocating that we violate that agreement. Hopefully we will take the opportunity in Dallas to engage in meaningful dialogue about how we work together to end mass killings in America."President Trump spoke at the 2017 NRA convention, which was held in Atlanta. It's not known if he will attend the 2018 meeting.  3059
