now he says, that was wrong. >> every day we held on to the video, contributed to the public's distrust. and that needs to change. >> reporter: but the problems go deeper here, and emanuel touched on a root cause when he recalled being asked a question recently by a young black man. >> he said, "do you think the police would ever treat you the way they treat me?" and the answer is "no." and that is wrong. and that has to change in this city. that has to come to an end, and end now! >> reporter: now the mayor says he won't resign, and the protesters out on the street tonight say they won't quit until he does. scott, it's a test of wills with no middle ground. >> dean reynolds, thanks. a new study finds that america's middle class is not only struggling but it is

today, a new study grabbed our attention. the middle class is no longer the majority in america. in 1971, 61% were considered middle class. now that's down to 50%. anthony mason tells us why. >> reporter: meredith riley, a 37-year-old social worker in new jersey, used to think of herself as middle class. >> it was the good life. it really was. it was wonderful. and now if i don't go to work, i don't get paid. >> reporter: her county job, which paid about $50,000 a year, was eliminated in the recession. a single mother of two, riley now works three part-time jobs and makes less money. >> i think the toughest part is not preparing a future for my children that my parents prepared for me. >> reporter: barely half of adults are middle income earners, defined as a household making between $42,000 and $126,000 annually. the percentage has been falling steadily since 1971.

as the middle class has hollowed ut, the upper income bracket has grown from 14% to 21% of americans. that upper class takes home of nearly after of all annual income in the u.s., 49%, up from 29% in 1970. >> it's not that middle americans are worse off, it's they're falling behind relative to upper income adults. >> reporter: the lower-income tier has also grown from 16% to 20% since 1970. meredith reilly's been among them since she was laid off. she has a college degree and a master's, but little hope. >> i just don't feel like the jobs are out there, that are going to put me back to where i was. >> reporter: the pew study found the great recession hit the middle class especially hard, scott. their median wealth fell by 28% between 2001 and 2013.

this is the "cbs overnight news." >> welcome to the "overnight news." i'm don dahler. donald trump's proposal to ban all muslims from entering the united states has sparked outrage, both at home and abroad. but perhaps the hottest firestorm of controversy is raging in israel. the gop presidential front-runner plans to visit israel after christmas as a guest of prime minister benjamin netanyahu. many israeli politicians are up in arms, demanding trump be barred from the country, nearly a third signed a letter to netanyahu demanding that he refuse to visit with trump. netanyahu insists he doesn't agree with trump's proposal but

as an american presidential candidate, he's welcome in israel. major garrett has more. >> reporter: for once, the republican party thought its worst nightmare was a donald trump third party run, but after watching him ignore the constitution and draw withering criticism from the right, the left, and around the world for suggesting that america ban muslims, the gop is discovering having trump in the party can be a nightmare, too. donald trump defended what many in his party consider indensable. >> do you regret your ban on muslims, which some people think is un-american. >> not at all. we have to do the right thing. somebody has to say what's right. >> are you a bigot? >> not at all. >> reporter: the top republicans in congress who avoid commenting on the presidential campaign, came down hard on trump.

>> this is not conservatism. what was proposed yesterday is not what this party stands for and more importantly, it's not what this country stands for. >> this suggestion is completely and totally inconsistent with american values. >> reporter: ben carson and marco rubio joined the chorus. >> we do not discriminate on people based on religion. that's constitutional, that's in the first amendment. >> i would say that or a religious test would violate the constitution. >> reporter: ted cruz, who is now surging in iowa, refused to say if trump's plan violated the constitution. >> i disagree with that proposal. i like donald trump. a lot of our friends here have encouraged me to criticize and attack donald trump. i'm not interested in doing so. >> reporter: jeb bush was asked to promise not to back trump if he became the nominee. >> i can guaranty donald trump is not going to be the nominee.

>> the question now is about the rest of the republican party. >> reporter: republicans in congress say they will vote for trump if he becomes the gop nominee. in an interview with bloomberg, joe biden called trump's ideas "a dangerous brew" and if he is the nominee, hillary clinton wins in a walk. investigators say the husband and wife killers quhinld the san bernardino massacre had been talking about staging an attack for two years. the pair war radicalized before they met and before the wife was allowed into the country. carter evans has the latest. >> reporter: authorities say both shooters pledged their allegiance to isis, and cbs news has learned that farook took out a large loan and that the couple may have planned to use that to support the daughter they would leave behind.

before killing 14 people at a holiday party last week, syed farook received a $28,500 loan, and investigators are trying to follow the money. they're also questioning enrique marquez, a long-time friend of farook who purchased the assault rifles used in the attack. his family had no comment tuesday. it's unclear if farook's mother knew about the pending attack. last week fbi agents seized several items after searching their black lexus, including targets from the gun range their son visiting. for the first time we're getting a look inside the room where the two shooters opened fire. this photo shows julie swan receiving an award just before the attack. she was shot twice in the pelvis, but survived. and now more than a dozen first responders are sharing their

stories. >> i don't feel like a hero whatsoever. >> reporter: detect jorge lozano was captured on video leading survivors to safety. >> there was a female with an 8-year-old boy that was terrified and i said what i said. >> i'll take the bullet before you, that's for damn sure. >> reporter: did you feel exposed? like when you opened that door the shooter would be on the other end? >> yes, sir. >> reporter: nicholas was shot in the thigh in the final confrontation with the killers. he left his vehicle to pull another officer to safety. >> when i was hit, the man was already down on the street. so i did not know who was in the back of that car shooting at us, but i could hear rifle fire coming out of that car. >> reporter: you know that was tashfeen firing at you? >> i do now. >> reporter: two of the buildings are going to remain closed at least through the end of the year. the build bring the attack took place is going to remain closed

indefinitely. another chipolte restaurant has been linked to an outbreak of food born illness. this one year boston college. >> reporter: we are roughly a mile from campus in a local shopping area, and this restaurant is very popular with students. but boston college officials say in recent days, some 80 students have come to the school's health services depth complaining of illness, and all said they ate here over the weekend. boston college says students showed up by the dozens at a campus health center this week to say they're sick, including several members of the men's basketball team who said they had eaten here. >> you never think about it. you just go and want to get food on the weekend. >> reporter: she ate there saturday and -- >> i've been having stomach problems.

it's not that bad. >> reporter: students suffered symptoms, including vomiting and diarrhea. the boston public health commission says lab results indicate norovirus. city inspectors closed the restaurant, temporarily, citing it for three violations. the news comes just six weeks after an e. coli outbreak. chipolte closed 43 runlts in the northwest. 52 cases of e ko. coli were reported in nine states. the company said there are no confirmed cases of e. coli connected to chipolte in massachusetts. they told us all employees

not everyone was shot when former singer scott weiland was found dead. he had a long history of drug abuse and his family does not want fans to glorify his passing. anthony mason reports. >> reporter: the medical examiner has yet to release a cause of death, but cocaine was found in the bedroom where his body was found. his addiction problems were well known, and now an essay written by his second wife, with help from their two children, reveals the devastating toll it took on his family. ♪

addiction and loss were common themes in scott weiland's music. the video for "fall to pieces" actually depicts him overdosing on heroin. drugs helped break up his turbulent 7-year marriage, with whom he had two children, noah 15, and lucy, 13. writing in rolling stone, weiland often forgot his own lyrics. >> she add, the truth is, like so many other kids, they lost their father years ago. ♪ he rose to fame as the lead singer for '90s grunge band

>> reporter: a lot of the talk of the paris conference is of the need to develop new, clean energy technologies. wind and solar power we know about, but they're not enough. now there's a new kind of power about to come on stream and it may be part of the answer. the power of the oceans. until now, the pounding waves along this part of the north coast of scotland have been largely left to the local population of seals. but lately the seals have had company. engineers. the conditions are finally right to start tapping the immense energy potential of the oceans and the world's most ambitious tidal project is well under way here. already a network of cables have been laid on the sea floor. soon, the first underwater turbines will be lowered into position, where the massive tidal forces will turn their rotors and make electricity. david tap is the site project

manager. >> the atlantic is that way, and the tide runs back and forth here four times a day. twice in each direction. >> yes. >> reporter: the tidal currents on this bit of coast are ferocious. the atlantic tide rushes through the channel, as it forces its way to the north sea. and then when the tide turns, it rushes back again. the plan is for a full field of turbines to be installed on the seabed where they will produce as much power as a conventional shore side coal, gas, or nuclear fired plant. the tidal plant will not suffer from the pitfalls of other renewable sources. solar power only works when the sun shines. and wind farms only work when the wind blows, which it isn't here. >> tidal has one distinct benefit. it's virtually 100% predictable. >> reporter: and says tim cornelius, ceo of the company, there's another advantage,

unlike wind farms, which are criticized for spoiling the view on land or for being hazardous to shipping at sea, with tidal -- >> you don't see it or hear it. it's very environmentally benign. >> reporter: that there's been power in the oceans have always been known. the tidal currents move back and forth like clock work. the trick has been to develop technology as reliable as the tides. and that, the developers say, is where we are now. the technology, however, is expensive right now. about twice the cost of wind generating power. but cost, the backers say, will come down quickly because tidal is adapting technology already used in the wind and offshore oil industries. >> the best thoughts around the world are yet to be developed. >> reporter: among the north american sites being looked at, the bay of funde off nova scotia, where the world's strongest ties run.

and on the west coast, san francisco bay and the famous tidal race under the golden gate bridge. the paris conference is moving into the deal or no deal stage. with three days to go, it's still dealing with carbon emissions. on the menu this overnight, boiled peanuts. they apparently taste better than they sound. susan spencer found the key in a south carolina parking lot. ♪ we love the peanut dude, we think you're going to love him, too ♪ >> reporter: meet chris, aka the peanut dude. >> fruits, veggies, nuts. >> reporter: definitely a little nutty. >> we have traditional boiled peanuts. >> reporter: boil what? if you're asking why would anyone boil a peanut, you're probably not from the deep south. >> boiled peanuts take me back

proportion and greece and the refugee crisis, which was no surprise to anyone. and i was wanting to go there to see if i could do anything. i went to greece, because i needed to reconnect with reality. i needed to meet a family that was struggling in this real crisis. i wanted to hold a baby in my arms. so we went to lesbos. 500,000 people had come through there since the crisis began. the first two days i was there, there wasn't a single boat i arrived. the final day we were going to the airport and people said, the boats are coming. so we ran. we had four or five blocks to run down the beach, and we got there just as the boat was arriving. and it was packed with all these people and they rain right on the beach and the people started flying out of the boat. i get to the boat and i walk up and i held the boat and a father puts his child into my arm and she had a facemask on.

and i lowered the facemask and she wasn't moving, and her eyes were closed. and i thought, oh, my god, she's not alive. and my mouth said, she's sleeping, but i remember thinking she was not alive. and then the father started to lose it. he came back and choked back for a minute. i was trying to find a put, but i couldn't. then i put my baby finger in her hand, and i swear it moved. and i thought, oh, god, she's arrive. then he just took the family away with the crowd and they were gone. i got this information as i landed in athens, the protection team followed up with dad and daughter and they were taken by ambulance to the hospital. she was born with a breathing disorder and suffers from epilepsy. at the center, they gave her

medications and the teams helped coordinate an expedited registration. the family was reunited. i was relieved. where are you from? >> afghanistan. >> what's at risk if we don't help these people is a moral crisis. that's what is at risk. >> welcome to the rest of the world. >> fear is the poison of our lives. we're all afraid of so many things. anybody who doesn't understand that and have some empathy toward fear that people have all over the world isn't being kind. fear is very real. but there's nothing to be afraid of here. nothing at all. >> you're welcome. >> our humanity is at risk if we don't take care of these people.
