immediately switched to the second phone and third phone calls i had to make, to her father and her mother. and then trying to figure out how to tell the kids their mom wasn't coming home.

>> what do you want your kids to hold onto when they think about their mother? >> kind, loving, caring, sharing, 100%. and that's every decision we make, it's going to be based on that. when i have those four eyes looking at me seeing how we're going to get through, that's going to make me a better dad and better husband and a better person. >> do you see her as your guardian angel now? >> absolutely. she was before. we met when we were teenagers. i didn't know it, now i do. >> if you could talk to her today, what would you tell her? >> i love you. i have no idea how i can do this without her, but because of her i know i can. it's a love affair that will never end and it won't because no one can take her from my heart. no one can take her from our family. >> he says he knows there are going to be some dark days ahead for him and his two kids, 12-year-old avery and 10-year-old josh as they really start to grieve their loss. they are carrying around these coins guardian angel coins.

they handed them out to jennifer's memorial over the weekend. it's a reminder she is looking out for them. >> so difficult to hear all of that. in china jay walking could land you on a no-fly list. the country has begun taking extreme measures to purify its society by impose a scoring system for social behavior, keeping track of surveillance cameras. ben tracy reports up to 600 million are set to be installed within two years. >> reporter: in some of china's largest cities, a high-tech effort is underway to bust low-level offenders. jay walkers. cameras record them going through intersections, zero in on their face, and then publicly shame them on nearby video screens. it's all part of the chinese government's new social credit system where people's daily behavior is monitored and rated. i think it's a good thing,

this woman said. it makes people more honest. but the social credit rating goes far beyond a traditional credit score which is based on your finances. china's version factors in everything from jay walking to smoking on trains to buying too many video games. if your score gets too low, you can be banned from buying plane tickets, renting a house, or getting a loan. nearly 15 million people have already been prevented from traveling. journalist leo who is one of them. he recently tried to book a flight but was told he couldn't because he was on the list of untrustworthy people. i can't buy property. my child can't go to private school, he says. you feel like you're being controlled by the list all the time. >> if you can't recognize more than 4,000 vehicles. >> reporter: chinese technology firms such as sense time are helping the government effort by developing advanced cameras that use artificial intelligence to track just about everything.

this knows every person, every bike, every car, every bus that goes through the frame. >> you can tell whether it is an adult, a child, male or female. >> reporter: police in beijing have been wearing these glasses that can recognize faces linked to the government's national database to help boost arrests. the fear, of course, is that the government may use this social credit scoring system to punish people that it deems not sufficiently loyal to the communist party and trying to clear your name or fight your score is nearly impossible because there is no real due process. jeff? >> wow, ben tracy in beijing. ben, thanks. coming up next, magician david copper field takes the stand to defend one of his tricks.

well, here's to first dates! you look amazing. and you look amazingly comfortable. when your v-neck looks more like a u-neck...

that's when you know, it's half-washed. add downy to keep your collars from stretching. unlike detergent alone, downy conditions to smooth and strengthen fibers. so, next time don't half-wash it. downy and it's done. magician david copper field testified today in a las vegas courtroom. he is being sued by a british tourist who says he was seriously injured participating in one of copperfield's tricks, the secret of which has now been revealed.

here's jamie yukis. >> reporter: david copper field has wowed crowds at the mgm grand for more than 20 years. today he took center stage on the witness stand. >> i'm not in the business of hurting people. >> reporter: one of copper field's signature illusions in his show is called 13. where members of las vegas audience disappear. bennedi bennedict moelli claims he was severely injured in a trick in 2013. >> it's a accident waiting to happen. >> reporter: he revealed how the illusion works in court. once the curtain obscures the participants, stagehands swoop in and lead them by flashlight through a series of back stage passage ways, out of the building then back in where they reappear in the back of the room. >> is it important to you for them to do it as quickly as possible or not? >> no, safety would always come

first. >> reporter: but morelli says that's not true. his client slipped during the act suffering brain, spine and shoulder injuries. his medical bills now total $1.3 million. after hearing about the case, he says two new female participants now say they also were rushed through the passage way and also injured. >> can you tell me the injuries we're talking about here? >> i know that one of them had multiple surgeries to her arm. >> reporter: copper field no longer performs the trick, but the magician's lawyer claims 55,000 audience members have participated in it through the years, and no one has been hurt. insisting they were moved along in an orderly fashion. >> i check them with myself every show. >> reporter: the defense asked for a mistrial after the interview with cbs news. the judge denied that mistrial. by the way, the two women who were injured are expected to testify later this week, jeff. >> jaime yukis outside the mgm

grand where david copper field performs. when we come back, how truckers banded together to stop a man from committing suicide. i was wondering if an electric toothbrush really cleans better than a manual. and my hygienist says it does but they're not all the same. who knew? i had no idea. so she said, look for one that's shaped like a dental tool with a round brush head. go pro with oral-b. oral-b's rounded brush head surrounds each tooth to gently remove more plaque, and oral-b is the first electric toothbrush brand accepted by the american dental association for its effectiveness and safety. my mouth feels so clean. i'll only use an oral-b. oral-b. brush like a pro.

we just switched to geico and got more. more? they've been saving folks money for over 75 years. a company you can trust. geico even helped us with homeowners insurance. more sounds great. gotta love more... right, honey? yeah! geico. expect great savings and a whole lot more. a tennessee judge today revoked bond for travis reinking

accused of murdering four people at a waffle house in nashville on sunday. reinking is on suicide watch. the police have released 911 tapes from his arrest in woods less than a mile from the restaurant. >> it looks like this guy. he's got mud all over him. he's a white male. looks to be about maybe 5'10", 6 foot. wearing tan pants, dark shirt and back pack. get somebody over here. this is where he lives. if that's the suspect y'all are looking for. >> today four crosses were placed outside the waffle house, one for each victim. the call came into michigan state police early today. a man on a highway bridge threatening suicide so officers directed truckers to lineup side by side beneath the bridge to break his fall if he jumps. they stay there for four hours as police talked the man out of it so he could get medical help. up next here tonight, the first lady gets ready for her first state dinner.

ivanka trump and jared kushner, the vice-president and mrs. pence and house speaker paul ryan among the guests arriving at the white house for tonight's state dinner for the president of france. melania trump, who has kept a low profile as first lady, is stepping into the spotlight as planner in chief of this event. here's jan crawford. >> reporter: she's been a woman of few words, considered so mysterious, even her clothing choices are scrutinized for clues. tonight's state dinner is a milestone moment, only for international diplomacy, but for the first lady. the white house released this video of her overseeing every

detail while her husband likes things big, bold and name branded, their first state dinner will be smaller and with fewer celebrities than those in the past. it reflects a confident first lady who is increasingly more visible, attending the funeral of barbara bush. last week hosting the japanese prime minister and his wife at mar-a-lago. >> i want to help people everywhere to be their best. >> reporter: earlier she invited middle school students to the white house to talk about issues facing children. something this mother of a middle school son has at heart. the media hasn't exactly embrace the her. trump supporter james woods pointed out an apparent double standard on twitter. michelle obama graced more than 30 magazine covers when her husband was president. so far mrs. trump has been on exactly one and only one foreign magazine. nearly 20 years ago when she was dating mr. trump, "the new york

times" said she might be the perfect political spouse. she said then if she ever became first lady, she would be traditional like jackie owe nasa is. and since the inauguration, when she first drew comparisons to jackie o., she's weathered her husband's stance with dignity, much like her famous predecessor. >> melania is the center like jackie was the first lady. >> reporter: a long-time friend of both trumps. >> we have seen clearly the way that she is changing the white house, the way she is decorating the white house . she has her own taste, very elegant, very classy. >> reporter: and he says very ready for the growing spotlight on the world's greatest stage. jan crawford, cbs news, washington. >> that is at overnight news for this wednesday. for some of you the news continues. for others check back later for the morning tz and cbs morning. from the broadcast center in new york city, i'm jeff lore.

>> announcer: this is the cbs overnight news. >> hi, everyone and welcome to the overnight news. i'm de marco morgan. president trump hosted french president emmanuel macron and his wife at a lavish state dinner at the white house. it is the first dinner of the president. the two have struck a friendly relationship and that may help with thorny issues they face, including the iran nuclear deal. chip reid has this story. >> reporter: in the oval office today, president trump lashed out at iran. >> they're not going to be restarting anything. >> reporter: he was referring to a threat by iran's foreign minister on sunday on face the nation with margaret brennan. >> you're ready to restart your nuclear program if president trump puts sanctions back on iran, even if the rest of the

world says don't do this? >> the rest of the world cannot ask us to unilaterally and one sidedly implement a deal that has already been broke. >> if they restart it they're going to have big problems, bigger than they've ever had before. >> reporter: it's a tough issue for french president macron who is trying to persuade mr. trump to stay in the deal. arguing there is no plan b for stopping iran from getting nuclear weapons. after meeting with mr. macron, mr. trump seemed open to a possible compromise being worked out by european allies. >> but there is a chance, and nobody knows what i'm going to do. >> reporter: on the other hand, the president today had kind words for north korea's kim jong-un, who already has nuclear weapons. >> he really has been very open. and i think very honorable from everything we're seeing. >> reporter: that's a stark contrast from his previous comments. >> little rocketman, he is a

sick puppy. >> reporter: the change is a reflection of just how badly mr. trump wants to meet with him, although he also tried to lower expectations for any possible meeting. >> maybe it will be wonderful, maybe it won't. >> reporter: the news on iran and north korea came on a day otherwise filled with pomp for the official arrival of macron who mr. trump calls a special friend. it included a double kiss, some personal grooming. >> in fact, i'll get that little piece of dandruff off. >> reporter: some hand holding and finally -- >> i like him a lot. >> reporter: president macron will speak before a joint meeting of congress where he is expected to argue once again that the united states should stay in the iran nuclear deal. but in the end it's not up to congress. it's up to macron's good friend president trump. president trump's nominee to head the veterans affairs department could soon bow out. senators have dug up disturbing accusations against dr. ronny jackson. president trump said it is up to

jackson to decide if he still wants the job. >> the fact is i wouldn't do it. i wouldn't do it. what does he need it for? to be abused by a bunch of politicians that aren't thinking nicely about our country? i really don't think personally he should do it, but it's totally his -- i would stand behind him, totally his decision. >> jeff gore discussed the nomination. >> reporter: the senate veterans affairs committee told npr this afternoon he heard from 20 active duty and ee tired personnel. they've come forward with concerns about the way he prescribes pills. for them to stay awake on long overseas trips. he was drunk on duty and a hostile work environment, he was abusive toward staff and had a, quote, very explosive personality. the navy did an quin iri in 2012 and found a negative command climate, but a follow-up in 2013 found that things had improved.

>> ed, so, we saw what the president said today. how is the white house responding to all of these allegations? >> the wlous is doubling down, jeff. the senior administration official a little while ago disputing that navy reports that it was a mere tiff between jackson and another colleague, a senior white house official said the other colleague was bitter and dr. jackson's record as a white house physician is impeccable and he's been given a clean vet from the fci. the doctor's nomination is on life support. >> the alleged driver in the toronto vana tack has been charged with ten counts of murder. the attack highlights the problem faced by cities around the world. how do you keep the streets safe? here is jeff. >> reporter: the goal is to prevent what happened in toronto and a repeat of what happened in new york last october when someone drove a truck down the length of a bike path in lower

manhattan, killing eight people. also in light of that attack, new york city officials, the mayor there called for spending $50 million to install 1500 additional barriers in las vegas city leaders have called for a hundred additional barriers along the sidewalk and along the strip. this has become standard operating procedure in major cities across the country. washington, for example, is instituted parking restrictions to limit the number of cars on the streets during some major events. but the reality is you cannot protect every block in every city and law enforcement officials will tell you it takes a mix of intelligence gathering and public awareness. >> until last week, no passenger had died in an accident aboard a southwest airlines jet in the company's 47 year history. a small consolation for the

family of jennifer reardon when it exploded. >> she called me that morning. called to check on the day, what we were going to do that night when she got home. we ended with, i love you, safe travels. >> how did you find out about what had happened? >> there was a chaplain from the hospital that called. he said i'm from philadelphia. i forget the name of the hospital. i said, well, my wife is flying to chicago today, so you must be looking for somebody else. and he said there's a plane that was diverted here. i'm going to have to have a doctor give you a call. the doctor called and said, i'm sorry, michael, but we've done everything we can and we couldn't save her. and i just dropped the phone and immediately switched to the second phone and third phone calls i had to make, to her father and her mother. and then trying to figure out how to tell the kids their mom wasn't coming home. >> what do you want your kids to hold onto when they think about their mother? >> kind, loving, caring, sharing

100%. and that's every decision we o that. when i have those four little eyes looking at me seeing how we're going to get through, that's going to make me a better dad and kind of better husband and better person. >> do you see her as your guardian angel now? >> absolutely. she was before. she's been that since the day we met when we were teenagers. i didn't know it then, now i do. >> if you could talk to her what would you tell her? >> i love you. just, um, i have no idea how i can do this without her, but because of her i know i can. it's a love affair that will never end and it won't because no one can take her from my heart. no one can take her from our family. >> reporter: reardon says he knows there are going to be some dark days ahead for him and his two kids, 12-year-old avery and 10-year-old josh as they really start to grieve their loss. they're carrying around these coins, guardian angel coins. they handed them out to some 2000 people who came to jennifer's memorial over the weekend. they say it is a reminder that jennifer is still with them and looking out for them.

>> announcer: this is the "cbs overnight." >> the communist rulers of china have been brought into a crash course to give all 1.4 billion chinese citizens a social credit score. it may sound funny, but it involves putting every person in the country under surveillance or as close as they can get to that. ben tracy tells us how it works. >> reporter: the government here says it is trying to purify society by rewarding those who are trustworthy and punishing those who are not. so, like the credit score that most americans get for how they handle their finances, chinese citizens are now getting social credit scores based on everything from whether they pay their taxes on time to how they cross the street. when leo hu recently tried to

book a flight, he was told he was banned from flying because he's on the list of untrustworthy people. leo was is journalist ordered by a court to apologize for a series of tweets he wrote and was then told his apology was insincere. i can't buy property. my child can't go to private school, he says. you feel you're being controlled by the list all the time. and the list is now getting longer, as every chinese citizen is being assigned a social credit score, a fluk waiting rating based on a range of behaviors. it is believed that community service and buying chinese-made products can raise your score. fraud, tax evasion and smoking in nonsmoking areas can drop it. if a score gets too low a person can be banned from buying train and plane tickets, real estate, cars, and even high speed internet. it's a good thing, this woman says. there should be punishment for people who can't behave.

china's growing network of surveillance cameras makes all of this possible. the country already has an estimated 176 million cameras and it plans to have more than 600 million installed by 2020. >> if you can recognize more than 4,000 vehicles. >> reporter: he is the ceo of sense time, one of the china's most success of the artificial intelligence companies. it has created smart cameras for the government that can catch criminals, but also track average citizens. this knows every person, every bike, every car, every bus. >> it can tell whether it is an adult, a child, male or female. >> reporter: in several big cities in china, including here in shanghai, the government is even tracking jay walkers. cameras record them going through intersections, zero in on their face, and then publicly shame them on nearby video screens. wen da was kin has studied china's economic and political

for decades. it is kept see krelt acret and easily abused by the government. how far mundane does this go? >> they'd like it to go as deeply as possible to learn how to give benefits and shape behavior. >> reporter: there is an up side the chinese government considers trustworthy. they can get better interest rates at banks, discounts on their energy bills, and china's largest online dating site reportedly even boost the profiles of people with high social credit scores. >> american farmers are finding it increasingly difficult to find laborers to work their fields and livestock. some farmers are turning to high-tech machines operating with artificial intelligence to fill the gap. dale barnett has the story. >> reporter: we know that farming is tough work. you've got to get up before dawn and to take care of cows like these, you have to bring them

through this milking machine twice a day. generally speaking this is not the type of work people want to do any more. it is becoming more difficult to find all sorts of agricultural labor. now, farmers i met with recently told me that the key to fix that is artificial intelligence. look at that bad boy. >> try it. should be sweet. >> reporter: for just about 1900 years -- wow -- his family has been running the wish farm business. >> if my grandfather was alive he'd be totally mesmerized by what the future has turned into. >> reporter: in order to keep his crop healthy, he needs 600 people to harvest 600 acres every two to three days. but finding that amount of labor is becoming unsustainable. >> we've seen a shrinking labor force and an aging labor force. we actually had fields we were abandoning early in the season, which is a really painful thing for a grower to do. >> reporter: in an effort to avoid losing $20,000 per acre on

abandoned fields, gary partnered with a teamful engineers who are working to fully automate the process. >> we've separated all the things a picker is doing and the various pieces of the robot. >> reporter: paul is the chief operating officer of the company behind it all. >> we're collecting 50 to 100 images fed into the a.i. system. this is a good berry, this is one we want to go after. >> reporter: so you're telling me in real time this machine is looking at the plant, thinking what to do next based on the imaging and then executing that action? >> exactly. >> reporter: is this as fast as a human now? >> this machine commercialized will replace the 30 people you saw in the field earlier today with gary. >> reporter: strawberry farmers are so excite ed about this harvest. two-thirds of the industry invested more than $5 million into its development. all in hopes to replace the cost of human labor. some would complain that machines and artificial

intelligence are actually displacing people who want to have these jobs. you're saying this actually fixes a problem you have. >> the work force is not here. we currently had to turn to guest worker visas to bring people in on a short term basis to get the crop harvested. this is a global problem. the lack of farm labor. >> john deer combine advisor. >> reporter: farmer main stay john deer has turned to autonomy and is expanding into silicon valley. it spent more than $300 million on a tech start-up using drone imaging to reduce use of pesticides. it helps me to check on my cows. >> one dutch company is using tensa flow, going's a.i. program. >> it can determine whether she's eating, drinking, whether she's lying down, standing up, walking. >> reporter: he hopes the app can give him a heads up if his

for food sustainability is how this new food tech will change things. >> it can't all be about profit. it has to be about the long-term viability of the food system and food security for everyone. >> reporter: back in florida where commercialization of these ai bots is years away, they say the consumer is the focus. how excited are you about what you're doing here? >> i'm really excited. someone recently asked me what i wanted my legacy to be. i think i saved the u.s. strawberry industry. >> reporter: you can expect to pay a lot for strawberries in the winter season. this new baby calf last night,
