Two people were killed and seven others were wounded in a shooting in North Carolina’s largest city, police said, while five others were hit by vehicles afterward.The shooting happened around midnight at an “impromptu block party” that was a continuation of Juneteenth celebrations, Charlotte-Mecklenburg Police Deputy Chief Johnny Jennings told reporters early Monday.Police responding to a call about a pedestrian hit found hundreds of people in the streets, Jennings said. As emergency services arrived, several shots were fired, scattering the crowd. Jennings said there was evidence of multiple shooters, but no one was in custody as of Monday morning.The five people were hit by vehicles while running away, Jennings said.The conditions of the 12 people hospitalized with injuries weren’t immediately clear.The shooting took place on Beatties Ford Road in northern Charlotte, police said.Further details weren’t immediately available. Calls, a direct message and an email from The Associated Press to Charlotte-Mecklenburg police weren’t immediately returned.Juneteenth, for which celebrations started Friday, commemorates when the last enslaved African Americans learned they were free 155 years ago. 1215

Twitter CEO Jack Dorsey says "we're ready to question everything" about the social networking site that has been overrun by spam, abuse and misinformation.Dorsey says he and his team are working extensively behind the scenes to stamp out some of the harassment and hate speech that has generated bad headlines lately.But it is a long-term effort, he says, and he is reluctant to commit to an exact timetable for certain changes to Twitter's foundation.In twelve years, "we've changed a lot. But we haven't changed the underlying fundamentals," Dorsey told CNN in an in-depth interview at the company's headquarters on Friday.The basic fundamentals are what he is examining now. For instance: What does Twitter incentivize its users to do?"Every product decision we make is 'telling' them to do something," Dorsey said.So he is thinking about how to help users follow topics and hashtags, not just people."We are aware of some of the silos and how we're isolating people by only giving them crude tools to follow accounts. We need to broaden our thinking and get more back to an interest-based network," he said.Related: Twitter's Jack Dorsey: 'We are not' discriminating against any political viewpointDorsey is also rethinking how follower counts and "likes" on posts are displayed, because the race to gain followers and likes may encourage outrageous behavior.His view is that Twitter needs to be much more "transparent" and open about its actions. But that transparency, some of which was on display during Dorsey's media tour this month, means asking questions without actually answering them.Among the questions Dorsey asked in the CNN interview: "How do we earn peoples' trust?" and "How do we guide people back to healthy conversation?"While he may get credit for asking big, philosophical questions about how his site operates, Dorsey remains vulnerable to criticism about Twitter's inaction.He responded to that by saying "we are taking a lot more action than we ever have in the past." But much of the action is invisible to users, he asserted.For example: The disabling of bot networks and other suspicious accounts. Dorsey said Twitter challenges "10 million accounts every single week to see if they're automations or humans," and takes action accordingly.But Twitter's stock plunged last month when its quarterly earnings report showed a decline in user growth, which the company attributed to its efforts to clean up the site, akin to gardeners removing weeds.Nonetheless, Dorsey is committed to what he calls "conversational health" -- the quality of an exchange on Twitter -- which he is trying to measure with the help of two research groups. He said investors should take a look at the long-term trends: "We see this as necessary and right and we believe in it and we have conviction around it, and we'll take the hit in the short term."Related: Twitter is purging suspicious accounts from your follower countHe also asserted that "over the short term, a lot of this work is invisible, and over the long term, it starts to add up."As for some of the specific changes, like a rethinking of the like button, Dorsey was reluctant to talk about a timeline."We're looking and thinking about all these things right now," he said. So: By the end of the year? "I worry about a time frame like that," he said, "because we also need to take into consideration -- we're a small company. I mean we, in comparison with our peers, we're a small company, but we have this outsized impact and I believe, importance."Later, he added, "We have to understand first the problem we're trying to solve, like what incentives we actually want to drive; not just what we want to remove, but what we want to drive." But he said he knows he wants incentives "that encourage people to talk and to have healthy conversation." 3824

Vermont Gov. Phil Scott on Wednesday signed sweeping gun control measures -- including limits on the size of magazines -- that the Legislature passed last month after contentious debate.The measures:-- Raise the minimum age for gun buyers to 21;-- Ban bump stocks, which allow semiautomatic weapons to fire more rapidly;-- Require all gun transactions to be facilitated by a licensed dealer who would perform background checks, except for law enforcement or military members acting within their duties, or for gun transfers between immediate family members;-- Limit rifle magazines to 10 rounds.State residents will be permitted to keep larger-capacity magazines they already own.As he signed the measures, Scott, a Republican, called himself a Second Amendment supporter who owns guns and has hunted his whole life. But he said continued mass shootings in the United States and a recently foiled school shooting plot at Fair Haven Union High School in Vermont "forced me to do some soul searching.""I want every student and every school, every mom and dad, every victim of violence in any form to know that today we stand together as we take steps towards making our community safer for all of us," Scott said.There were boos as well as cheers from people watching Scott as he made his remarks outside the Vermont Capitol.The Legislature's approval of the measures came as other states also consider gun safety restrictions since a mass shooting in February that left 17 people dead at Marjory Stoneman Douglas High School in Parkland, Florida.Scott had backed the new firearms safety legislation, which came after police foiled the plot at Fair Haven shortly after the Parkland shooting. 1717

United Airlines is sending layoff warnings to 36,000 employees, nearly half its U.S. staff. It's the clearest signal yet of how deeply the COVID-19 pandemic is hurting the airline industry. United officials said Wednesday that they still hope to limit the number of layoffs by offering early retirement, but they have to send notices this month to comply with a law requiring that workers get 60 days' notice ahead of mass job cuts. The furloughs would include 11,000 flight attendants, 11,000 customer service and gate agents, 5,500 maintenance workers and 2,250 pilots. United officials said the notices cover 45% of its U.S. employees.Air travel in the U.S. dropped about 95% by mid-April. It has recovered slowly but remains down about 75% from a year ago. 768
