From flooding to tornadoes, a deadly storm system blew through parts of the country over the weekend.At least eight people are dead, including three children, after severe weather slammed the south.Lily Pierce survived a tornado in Mississippi, after she took cover for three hours inside a storm shelter.“All the sudden, you’re crashing on the floor crying, praying it’s not you,” Pierce told TV station WBMA.At least 18 tornadoes hit four states. Two children died, when a tree fell on their car during a tornado outbreak in Texas.“You can't imagine that happening. I would never think of that, you know, a tree hitting a car while you're going down the road, so it was very upsetting,” said neighbor Joe Spangler.The children’s mother ran to Spangler’s house. begging for help.“She was like 'help me, help me,' so I pulled her in the house, and I saw down the road that her husband was down there, so I ran down there to see what was going on,” Spangler told TV stations KTRE. “When I got down there, I mean, I saw the size of the tree and how it was on the car. I knew it wasn't a good outcome.”More severe weather is expected this week and threatens some of the same areas hit over the weekend, as well as the East Coast. 1238

Hundreds of cities have put curfews in place because of the protests. That makes it so law enforcement can stop or arrest anyone on the street, but many protesters have ignored the restrictions. So, why do it? We spoke to an expert in policing who says it’s about separating those hiding in the crowd to incite violence and protecting demonstrators trying to have their voices heard.“It doesn't necessarily give power. It gives them the ability to contain better whatever it is that they need to contain,” said Dr. Maria Haberfeld, a professor of law, police science and criminal justice at John Jay College. “Whether it's rioting, whether it's looting, whether it's unlawful gathering of people.”Haberfeld says curfews have a history of controversy. They were used during the Jim Crow era against African Americans and against Japanese populations during World War II.Now, they're normally used for juveniles or during natural disasters like hurricanes. Haberfeld calls that the good use of curfews to protect the general population.Still, the ACLU has criticized curfews as unfair and unconstitutional, saying it gives police too much discretion over who to arrest. Haberfeld doesn't see it that way.“When a city's under siege, when a city's in danger of being burned and destroyed, that has nothing to do with unconstitutional,” said Haberfeld. “That has everything to do actually with serving and protecting people who live in the city.”Haberfeld says it's important to note that curfews are instituted by mayors or local governments, not by police chiefs or commissioners. She says police departments cannot and do not want to arrest everyone. 1660

General Motors’ self-driving car company will attempt to deliver on its long-running promise to provide a more environmentally friendly ride-hailing service in an unorthodox vehicle designed to eliminate the need for human operators to transport people around crowded cities.The service still being developed by GM’s Cruise subsidiary will rely on a boxy, electric-powered vehicle called “Origin” that was unveiled late Tuesday in San Francisco amid much fanfare. It looks like a cross between a mini-van and sports utility vehicle with one huge exception — it won’t have any steering wheel or brakes. The Origin will accommodate up to four passengers at a time, although a single customer will be able summon it for a ride just as people already can ask for a car with a human behind the wheel from Uber or Lyft.For all the hype surrounding the Origin’s unveiling, Cruise omitted some key details, including when its ride-hailing service will be available and how many of the vehicles will be in its fleet. The company indicated it will initially only be available in San Francisco, where Cruise has already been offering a ride-hailing service that’s only available to its roughly 1,000 employees.By eliminating the need for a human to drive, Cruise theoretically will be able to offer a less expensive way to get around — a goal already being pursued by self-driving car pioneer Waymo, a Google spinoff that has been testing robotaxis in the Phoenix area for nearly three years.Cruise had planned to have a robotaxi service consisting of Chevrolet Bolts working without human backup drivers by the end of 2019, but moved away from that last year after one of Uber’s autonomous test vehicles ran down and killed a pedestrian in the Phoenix suburb of Tempe, Arizona, during 2018.Still aware of the fallout from that deadly crash, Cruise is promising “superhuman performance” from the Cruise, which GM hopes to manufacture at half the price of comparable vehicles using fuel-combustion engines. GM also expects to announce where the Origin will be made within the next few weeks, Cruise CEO Dan Amman said.The Origin won’t be sold to consumers though. “It is not a product you can buy, but an experience you share,” Amman said.The Origin represents another significant step for Cruise, which had only 40 employees when GM bought it in 2016 as part of its effort to catch up in the race to build cars that can drive themselves. Since then, Cruise has attracted more than billion from investors, including .75 billion from Honda and .25 billion from Japanese tech investment firm SoftBank. Honda also helped develop the Origin. GM currently values Cruise at billion, fueling speculation that the subsidiary may eventually be spun off as a publicly traded company.Whenever Cruise’s ride-hailing service makes its debut, it will still be chasing Waymo, whose work on self-driving car technology began inside of Google more than a decade ago. Waymo’s Phoenix-area service already has given more than 100,000 rides, according to the company. It expanded beyond the test phase service 13 months ago with a ride-hailing app that now has about 1,500 active monthly riders, Waymo says.By comparison, ride-hailing leader Uber now boasts about 103 million active monthly users with a service that relies on human drivers — a dependence that is the main reason the company has been losing money throughout its history. Despite the fatal 2018 crash that stoked the public’s worst fears about self-driving cars, Uber is still trying to build a fleet of robotic taxis as part of its question to become profitable.Tesla CEO Elon Musk has also pledged that his company’s electric cars will be able to drive themselves without a human behind the wheel before the end of this year so they can moonlight as taxis when their owners don’t need the vehicles, but industry analysts doubt that promise will come to fruition. 3921

Facebook will unveil a new policy on Wednesday to restrict sales and limit content related to alcohol and tobacco products, including e-cigarettes, a company spokeswoman tells CNN.The new policy will prohibit all private sales, trades, transfers and gifting of alcohol and tobacco products on Facebook and Instagram, the spokeswoman said. Any brands that post content related to the sale or transfer of these products will have to restrict that content to adults 18 or older.The new policy will go into effect Wednesday and will also apply to any Facebook groups created to sell alcohol or tobacco products, the spokeswoman said. The social network is reaching out to group administrators to alert them of the changes.The company is enforcing the new rules, the spokeswoman said, and may remove any groups that do not make necessary changes. While the company's policies already prohibit the sale of tobacco and alcohol in Facebook Marketplace, the platform is extending its ban to "organic content" -- regular posts from private users.The company will "use a combination of technology, human review and reports from our community to find and remove any content that violates these policies," the spokeswoman said.Facebook and Instagram users, including those under 18, are still free to post other content related to tobacco and vape products.Under the new policy, so-called influencers who are paid to promote nicotine-containing products will also be allowed to post content related to tobacco and vape products. Those posts will not have to be age restricted, the spokeswoman said.She emphasized, however, that the company is considering possible changes to its influencer policy and is working with industry and regulatory bodies on potential revisions.Last year, a CNN investigation detailed how Juul, the largest vape manufacturer in the United States, paid popular Instagram users to promote its device. The company has come under fire in recent months for its alleged role in what experts call an "epidemic" of teen vaping. In 2018, the FDA announced that vaping increased nearly 80% among high schoolers from the previous year.Juul executives will testify this Thursday at a congressional 2211
