well, it looks a little like the arctic circle in the midwest, which is now blanketed in storm warnings. here's david begnaud. >> reporter: over the last 24 hours this has been the scene across much of kansas and parts of oklahoma. >> every time it crackles it means something else is coming down. >> oh, it's coming down. >> reporter: an inch of ice covered power lines that knocked out electricity to thousands of homes and businesses. oklahoma's governor declared a state of emergency in all 77 counties. >> you know, all night we could hear the limbs cracking and the ice falling and we just didn't know what to expect. >> reporter: at least four people died after major flooding in texas. authorities received nearly 37 calls for water rescues since thanksgiving. >> you are freaking lucky. >> i know. >> no way you should have survived that. >> reporter: in utah a

icy reservoir while trying to save her dog, who fell through the ice. mantua police officer brad nelson led the rescue. >> walking out onto the ice you could hear it cracking beneath my feet. there's not a whole lot she could have done to help herself at that point. >> reporter: here in minneapolis 8 to 12 inches of snow is expected over the next 12 to 24 hours. scott, across the midwest tonight some 8 million people are under a winter weather advisory. >> david begnaud reporting tonight. david, thank you. today the suspect in that shooting at a planned parenthood clinic in colorado springs made his first court appearance. he will face first-degree murder charges and perhaps the death penalty. three people were killed, including a police officer. nine were wounded. barry petersen is in colorado springs. >> the initial charge against you is murder in the first degree. >> reporter: robert lewis dear appeared by video link from the county jail, standing next to a public defender. he was asked if he had any

he answered in a monotone. >> no questions. >> reporter: sources say he went to the clinic on friday with a duffel bag full of weapons and brought propane tanks in his car he could shoot and cause an explosion. when he surrendered, he reportedly said, "no more baby parts." that may have been a reference to videos filmed and edited by anti-abortion activists where they say planned parenthood officials talked of selling body parts from aborted fetuses. an official from the group that includes the colorado springs clinic was among those in the videos. >> so anywhere from three up to seven. >> reporter: dear lived in hartsel, about 65 miles west of colorado springs in a mobile home. he was described as reclusive, a man who ever interacted with others and would rarely make eye contact. for the people of colorado springs this is a time of mourning for the dead. university of colorado police officer garrett swasey, mother

war veteran ke'arre stewart, who was there with his girlfriend. angelica llanca and her daughter alexis were in the clinic but separated when the shooting started. angelica hid in a bathroom. were you afraid you would be killed? >> i don't know. to tell you the truth, all i wanted was my daughter. >> reporter: alexis was among those evacuated hours into the siege. she is still traumatized. >> i can still hear the gunshots. >> now you can hear them in your mind? >> mm-hmm. >> reporter: it is likely that more charges will be filed in the next several weeks. as for the death penalty, scott, the local d.a. says that decision is several months away. >> barry, thank you. late today chicago police officer jason van dyke was released on $1.5 million bail. van dyke is charged with

mcdonald, who was armed with a small knife. the officer shooting mcdonald 16 times as mcdonald was walking away. a baltimore police officer went on trial today in the death of freddie gray, who suffered a spinal injury in april while william porter is charged with manslaughter. five other officers will be tried later. the city has been gearing up for this case, and here's jeff pegues. >> the city and the police department need to do better. >> reporter: kevin davis, baltimore's new police commissioner, says his department has been training for the trials and the unrest they could bring. >> we won't stop. >> reporter: are you ready for what may come during and after the trials? >> we are. >> reporter: davis acknowledges that wasn't the case in april. after freddie gray's death the city erupted. businesses were looted and torched. police officers were injured.

violent crime spiked and officers were accused of not being aggressive enough. there were concerns that they were pulling back. did that happen? >> i think a more thoughtful way to recognize what happened for a couple months here is this police department had ptsd. >> you said ptsd. is that a politically correct way of saying that they were taking a knee? >> i think it's a correct way of saying that cops had anxiety. >> reporter: davis's predecessor anthony batts was fired in july. but the killings continued. 311 homicides this year, a 59% increase over 2014. davis, who was deputy commissioner at the time of the rioting, says one reason the murder rate is up is this -- the looting of 30 pharmacies. suddenly 288,000 doses of prescription drugs were on the streets with gangs fighting for control. >> when they get their hands on their stashes, then there's a competition for the geography that they need to occupy to sell their drugs.

erupted. >> reporter: with the trials of those six police officers scheduled to extend straight into next year, davis says that he will treat a protest like a protest and a riot like a riot. scott, that is something he says the department did not do seven months ago. >> jeff pegues in baltimore. jeff, thanks. in the presidential campaign hillary clinton made news today when charlie rose asked her whether u.s. combat troops should join the fight against isis in syria and iraq. >> i agree with the president's point that we're not putting american combat troops back into syria or iraq. we are not going to do that. this fight -- >> under no circumstances would you not do that? >> well, at this point i cannot conceive of any circumstances

because i think the best way to defeat isis is, as i've said, from the air, which we lead, on the ground which we enable, empower, train, equip, and in cyber space where don't forget they are a formidable adversary online. so what i want to say is look, we don't know yet how many special forces might be needed, how many trainers and surveillance and enablers might be needed but in terms of thousands of combat troops like some on the republican side are recommending, i think that should be a non-starter. >> it was a wide-ranging discussion. don't miss it tomorrow on "cbs this morning." do more americans shop online or in stores? we were surprised. the "cbs overnight news" will be right back. i took mucinex dm for my phlegmy cough. yeah...but what about mike? he has that dry scratchy thing going on. guess what? it works on his cough too. cough! guess what? it works on his cough too. what? stop! don't pull me! spoiler alert! she doesn't make it!

with two medicines in one pill. start the relief. ditch the misery.

ever since darryl's wife started using gain flings, their laundry smells more amazing than ever. (sniff) honey, isn't that the dog's towel? (dog noise) hey, mi towel, su towel. more scent plus oxi boost and febreze. it's our best gain ever! jill and kate use the same dishwasher. same detergent. but only jill ends up with wet, spotty glasses. kate adds finish jet-dry with five power actions that dry dishes and prevent spots and film, so all that's left is the shine.

today, cyber monday, is expected to be the biggest online shopping day ever. more than 121 million americans plan to shop from home and work. our cbs news business analyst jill schlesinger is with us. jill, how big a day was it? >> it's going to be pretty big.

billion in sales, according to adobe digital. now, if we get there, it would be the largest online day of shopping ever. we have some early results from midnight to 10:00 a.m. 50 million visits to 4,500 websites in the u.s. those online shoppers spent that's up about 14% from a year ago in that same time horizon. these numbers are going to get bigger. >> are we getting to a point where more people are going to shop online than actually go into a store? >> i think eventually. but today absolutely not. if you look at the recent data from the commerce department, we know that online sales account 15%, 16% of total sales. maybe we'll drift up to closer to 20%. but you know, for now people still want to be in a physical location and spend their dollars there.

retailers couldn't handle the traffic today. >> yeah. this was pretty wild because over the last few days outages at very big retailers like nordstrom or victoria's secret, this morning a big outage at target. paypal down for a while. so technology not always perfect. with the advent of apps and information we're smarter, we're and the reality is we can now combat those algorithms that are targeting us so beautifully by being informed. >> business analyst jill schlesinger, thank you very much, jill. an olympic champion has

and we'll be right back. after cyber monday comes giving tuesday. michelle miller tells us that a lot of folks are getting into the spirit. >> that's the number of complete applications we have. >> reporter: at the giving tuesday command central in new york city volunteers are gearing up for tomorrow. so giving tuesday started right here at the 92nd street y? >> yeah, that's right. >> reporter: henry timms is the y's executive director. three years ago he came up with the campaign. >> we never needed more than six words. it was always black friday, cyber monday, giving tuesday, and people would really say yeah, i think that's a good idea. >> on giving tuesday everyone can be generous. >> reporter: his idea was simple. after several days of shopping he wanted people to refocus on giving. to any charity or purpose they

he asked others to help. >> they jumped right on the bandwagon. >> it was an amazing thing to see that actually all over the country people started to bring their own ideas to giving tuesday and started to grow it. >> reporter: the movement now has 40,000 partners worldwide and raised more than $86 million. >> you'll see these letters that the kids have written to their donor. >> reporter: charles best runs donorschoose.org, a charity which matches teachers' wish lists to donors. >> what's great about giving tuesday is people can be supportive, can be generous in any way they see fit. they can give of their time. they can give of their money. >> ready. >> reporter: genein letford teaches music in the los angeles area. she received dozens of instruments from the giving tuesday campaign. >> the cool thing is it's not just about bringing the materials into the classroom and making sure the kids have this opportunity, but it's connecting the community to our schools. >> at a time when we feel like the most public conversations are about things which threaten us or things that divide us, how valuable is it to have a conversation about something

>> reporter: a day expected to bring many thanks after much giving. michelle miller, cbs news, new york. that's the overnight news for this tuesday. for some of you the news continues. for others check back with us a little bit later for the morning news and of course "cbs this morning."

york city, i'm scott pelley. >> announcer: this is the "cbs overnight news." welcome to the "overnight news." i'm jericka duncan. president obama and other world leaders at the international climate summit in paris got some words of warning from pope francis. on his way home from a week-long pilgrimage to africa pope francis warned that the world is in his words at the limit of suicide and that it is now or never to reach an agreement to limit global warming. president obama echoed those sentiments monday in paris. >> we're here because we recognize the urgency of climate change and we believe that there's something that we can all do about it. as long as we work together.

in paris will be forged by governments, the ambitious targets that we set for ourselves are going to be reached in large part by the efforts of our scientists, our businesses, our workers, our investors. >> margaret brennan is at the paris conference. >> reporter: the world's two biggest polluters, china and the u.s., kicked off the climate change summit. >> it's our responsibility to take action. >> reporter: a pledge made as smog climbed to dangerously high levels in china. the goal in paris is to limit global warming to 6.3 degrees fahrenheit from preindustrial levels. but the terror threat is diverting attention. the president's first stop on french soil was to pay his respects last night at the bataclan theater, site of the worst of the paris attacks. france remains on high alert. a 120,000-strong security force is stationed across the country. riot police have been deployed in unprecedented numbers. on sunday 174 protesters were arrested for defying the

demonstrations. former diplomatic security agent bruce tully has spent 40 years protecting dignitaries around the world. >> i think this is one of the highest-risk environments i've seen professionally in my career. there's so much threat analysis out there, not just from isis, copycats, but also because of the protesters for the conference itself. >> reporter: environmentalists silently protested the ban on their march, leaving their shoes in the square they had hoped to walk through. a cbs news/"new york times" poll shows that 53% of americans believe global warming is caused by human activity. 31% think natural weather patterns are the biggest factor. american experts are working in some of the world's most forbidding places to study the impact of global warming. mark phillips has the first installment of our series "the climate diaries." >> reporter: while world leaders

do about climate in paris, but some of the most important research on the subject is being done about as far away from civilization as you can get. this is svalbard, a collection of norwegian islands just 800 miles from the north pole. and it's where a young american climate scientist has come to try to unlock some of the secrets of climate change that have been frozen into this landscape for tens of thousands of years. sarah strand, a 22-year-old californian, won't see the sun again until mid february. the polar night has set in, and darkness isn't the only thing to worry about up here. >> so i will take the flare gun if you want to take the rifle. >> okay. >> reporter: this is polar bear country, where sarah and her german colleague norbert pirk are required by law to pack protection. the bears are more of a threat in summer when the meltback of their sea ice hunting ground has made them more desperate for

attacking a research boat. but there's still a threat in winter, and it's in winter that this research must be done. >> this is basically your baby up here, is that right? >> yeah. it definitely has to be running if we're going to get all the data. >> otherwise all this suffering is for nothing. >> reporter: every day sarah comes out here to check instruments that are measuring a worrying trend. the release of greenhouse gases, which scientists used to think were safely locked into the frozen ground. >> the main thing we're looking at is the gas exchange with the ground carbon dioxide and methane. but then we're comparing that to other parameters that we're measuring here. >> what, like temperature -- >> exactly. >> the weather basically. >> yeah. >> reporter: and the more those greenhouse gases are released, even from frozen places like this, the more warming there will be. >> there are concerns of that, yes. especially with the permafrost thawing that there is now old carbon that has become --

possibly be released into the atmosphere. we're trying to shine some light on this. >> in the dark. >> in the dark. >> reporter: sarah has been here a year and a half, working in these conditions because the arctic is, ironically and worryingly, where the earth appears to be warming most. they call it arctic amplification. it's hard to tell on a day like this, but the arctic is warming sooner, faster, and more than anywhere else. why that's happening and what it means for the rest of us is why this little speck in the arctic has become the major center of climate research. >> you can't just measure one thing and say oh, climate change, but it's more about having all these monitoring projects and understanding how the system is working. >> reporter: another american, hannah miller, a 21-year-old from vermont, is here too. she didn't come for the skiing. she came to study how glaciers

their melt water contributing to sea level rise. climate change decisions, she says, have to be based on science. >> the frustration comes in when climate change deniers use any of the uncertainties to say that your argument is false. because you can have uncertainties and still have solid argument. >> hannah and sarah have joined a small, dedicated and brave community in svalbard. it's cutting-edge science up there on the edge of the world. on the campaign trail republican presidential front-runner donald trump met with a large group of african-american religious leaders. but the planned news conference was canceled after some of the clergy were told it was a chance to endorse trump's presidential bid. a lot of them said they were there to listen, not to give trump their blessing. major garrett reports. >> reporter: baltimore pastor and activist jamal bryant

lending their reputation to a campaign promotional flyer. >> why did those who participate in black lives matter look at the black church as a joke? and maybe it's because of these 100 preachers who have in fact prostituted the authenticity of the prophetic mantle. >> reporter: at least three pastors listed on the flyer have backed out. others like mark burns, who supports trump's candidacy, admit many african-americans still have questions. >> this meeting is -- again, it's a 911 cry that he has to be able to address some of these issues and not just do it privately but he has to come out and address it publicly. >> reporter: numerous other pastors scheduled to be at the meeting have released statements making it clear their presence is not an endorsement. one pastor said trump must address issues of racism and criminal justice reform. black lives matter protesters have encountered hostility at some trump rallies, episodes trump said little about during or after. the cbs overnight news will be right back. i have asthma... ...one of many pieces in my life.

on my long-term control medicine, i talked to my doctor and found a missing piece in my asthma treatment. once-daily breo prevents asthma symptoms. breo is for adults with asthma not well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. breo won't replace a rescue inhaler for sudden breathing problems. breo opens up airways to help improve breathing for a full 24 hours. breo contains a type of medicine that increases the risk of death from asthma problems and may increase the risk of hospitalization in children and adolescents. breo is not for people whose asthma is well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. once your asthma is well controlled, your doctor will decide if you can stop breo and prescribe a different asthma control medicine, like an inhaled corticosteroid. do not take breo more than prescribed. see your doctor if your asthma does not improve or gets worse. ask your doctor if 24-hour breo could be a missing piece for you. see if you're eligible for

red 97! set! red 97! did you say 97? yes. you know, that reminds me of geico's 97% customer satisfaction rating. 97%? helped by geico's fast and friendly claims service. huh... oh yeah, baby. geico's as fast and friendly as it gets. woo!

a cbs news investigation on the peace corps shows nearly 20% of volunteers experienced some type of sexual assault. more than half of those say they suffered repeat attacks. what's more, many who came forward say they suffered retaliation from their bosses. kris van cleave reports. >> reporter: nearly 7,000 peace corps volunteers are currently serving in about 65 countries, and according to a recent anonymous peace corps safety questionnaire obtained by cbs news, roughly 1 in 5 volunteers reported being sexually assaulted during their service. the report also shows nearly half didn't report the assaults. one volunteer wrote, "in reporting an assault i made myself a target." >> my thought was they're going to rape me, these men are -- these men are going to try to rape me. >> reporter: 23-year-old peace

been in the remote dominican republic town of los mesquitos for eight months when in april two men with machetes forced her smith fought them off and peace corps. within a week the agency told her she was going home. >> and they also told me that my attack had occurred because i had been walking in my sight and as a volunteer it was my job to prevent it from happening. >> reporter: more than 500 volunteers have reported experiencing a sexual assault in a little over two years. we spoke with nearly a dozen who questioned how their recent cases were handled. they told us they felt criticized and were threatened they would be fired. five years ago the peace corps, a government agency, faced intense scrutiny over its response to sexual assaults. congress passed a law, and the agency's then director vowed

>> i hired a nationally recognized leader in victims' rights to be our first agency's victim's advocate. >> reporter: that leader was kelly green. >> i'm getting phone calls and i'm getting e fails from returned volunteers that are in tears because they can't get the help that they need. >> reporter: cbs news found some peace corps employees attempting to limit the number of in-country counseling sessions for sexual assault survivors to a maximum of 6. in this 2014 e-mail a peace corps clinical psychologist said of a volunteer, "the need for ongoing therapy is an indication the volunteer was not a good fit for peace corps service." after another volunteer asked for additional counseling a peace corps medical officer sent this e-mail saying, "i'm sure this will make no difference in her behavior." >> i pushed the agency to really do what they have the capability of doing, and that's what's so frustrating because they have the ability to do this and it is a choice not to.

without pay for allegedly creating a hostile work environment. but green says she was punished for standing up for the victims she was hired to protect. bonnie scott was a peace corps volunteer in albania. earlier this year she says she alerted the peace corps one of its american officials was allegedly sexually assaulting albanian women. >> he was given the option to resign rather than face misconduct charges, which meant that everything would be covered up. >> reporter: shortly after the official sent this e-mail saying he was resigning for personal reasons, the peace corps fired scott for improperly filling out paperwork. >> they basically kicked me out ten days after they let -- >> reporter: inspector general reports show multiple cases of peace corps personnel accused in sexual assaults resigning ahead of administrative action and then being allowed to reapply to the agency. a 2014 i.g. report warned the peace corps screening process for rehiring was not detecting past misconduct.

violating the agency's sexual assault policy was later hired to work at the agency's headquarters in washington, d.c. >> that person's no longer employed by peace corps but i will also say that we are putting in place systems, mechanisms, to make sure that doesn't happen again in the future. >> person after person paints this picture of at least some percentage of the time there is what appears to be blaming or retaliatory responses to people who've just suffered a trauma. >> this is unacceptable to us, and we are trying to change the culture. our best indicator of volunteer satisfaction with our services is our sexual assault response quality survey. and 96% have said that they're satisfied with their service. >> reporter: that anonymous survey was sent to 183 people. just 52 responded. >> we have made enormous progress but it is a huge task and every single day we're providing better care. >> reporter: but denay smith

>> i feel like peace corps failed me every step of the way. >> so far the peace corps says it has instituted more than 30 reforms regarding sexual assault and works to retrain employees who appear unsympathetic to survivors. kelly green, the peace corps victim advocate that's been suspended by the agency, is pursuing whistleblower protection but the peace corps disputes any claims it retaliated against her. the death toll continues to rise after holiday weekend storms socked the midwest and plain states. police in fort worth, texas recovered a car that had been swept away by flood waters. there was a body inside that hasn't been identified. rachel calderone in yukon, oklahoma where many residents are still without power. >> reporter: just as hundreds of linemen are out here still working to restore power to yukon, oklahoma and to move the trees and open up these roads, a 4.5 magnitude earthquake struck early this morning, obviously complicating matters for those

to some 60,000 people. massive sheets of falling ice created close calls across the south as a deadly winter storm froze over trees. cars. and knocked out power for thousands. >> you know, all night we could hear limbs cracking and the ice falling and we just didn't know what to expect. >> reporter: for three days the relentless ice storm dumped freezing rain on oklahoma, causing extensive damage. >> oh, it's coming down. >> reporter: more than 71,000 homes and businesses were without power. oklahoma's governor declared a state of emergency in all 77 counties. >> we've been hearing it for two days, every time it crackles it means something else is coming down. >> reporter: there were extreme conditions in hutchinson, kansas.

that state. the violent winter storm smashed out car windows, split trees in two, and knocked down power lines. the line of severe weather also caused flooding in texas, where more than 38 people were rescued since thanksgiving. in amarillo two people were injured after this semi truck slammed into a restaurant. weather has been blamed for another eight deaths in that state. the earliest estimate for power to be restored is on tuesday. and because of this dozens of schools are still closed at this time. the cbs overnight news will be right back.ere for ya? ugh. my sinuses are killing me. yeah...just wait 'til we hit ten thousand feet. i'm gonna take mucinex sinus-max. too late, we're about to take off. these dissolve fast. they're new liquid gels. and you're coming with me... wait, what?! you realize i have gold status? do i still get the miles? new mucinex sinus-max liquid gels. dissolves fast to unleash max strength medicine. start the relief. ditch the misery.

an international conference in washington today will focus on a revolutionary technology that can edit genetic mistakes. it's called crispr, and it could rid the world of cystic fibrosis, muscular dystrophy, and even hiv and cancer. norah o'donnell spoke with one of the pioneers. >> what is crispr? >> first of all, it's an acronym. it stands for clustered regularly interspaced short palindromic repeats, a huge mouthful. you can see why we use the acronym crispr. >> so i'm sorry. what's crispr again? >> reporter: geneticist jennifer doudna gets asked that question a lot. a researcher and professor at uc berkeley, doudna has become a spokesperson for a gene editing technology she's credited with developing.

>> i've heard it compared to essentially like a film editor slicing a bit of film. >> i would say that's a great analogy, yeah. >> how does that work, then? >> you think about a film strip and you see a particular segment of the film that you want to replace and if you had a film splicer you'd go in and literally cut it out and piece it back together. maybe with a new clip. imagine being able to do that in the genetic code, the code of life. you could go in and snip out a piece and replace it with something that corrects a mutation that would cause disease. >> that's incredible. >> it's incredible. >> reporter: crispr hs generated immense excitement because it's fast, cheap, and can cut and paste genetic code with great precision. it used to take months or years to alter a single gene. now that can be done in a matter of days. >> could it end cancer? >> what i'm excited about there is the potential to use the

recognize tumor cells in a precise way. >> could it cure at some point virtually any disease? >> i don't know about any disease, but i think any disease that has a genetic basis is something that could be treated using the crispr technology. >> reporter: and imagine, doudna says we could expect to see clinical applications of crispr within the next few years. >> this is no longer science fiction. >> reporter: but alongside crispr's promise come some fears of its perils, like embryo editing that could lead to designer babies. >> what is the dark side of this technology? >> one of them is of course making changes to human embryos which become permanent. so we're talk about something that would affect human evolution. >> you could have an instance

human embryos just for the sake of experimenting on genome editing on them, right? >> if you're asking me could that be done technically the answer is it could. could it be done with current regulations in place? certainly not in the u.s. >> or europe. >> or europe, right. >> there's still a lot of other countries other than the u.s. -- >> well, science is global and there are different cultural viewpoints on that kind of application. >> reporter: in april chinese scientists reported using crispr to edit the disease genomes of human embryos for the first time pn't experiment was a failure but it sparked concerns worldwide. >> i and my colleagues have called for a global pause. >> reporter: doudna has long been vocal about the need to set ethical boundaries and is convening an international summit in washington, d.c. >> what do you hope comes out of that? >> i think it would be great if we can at least get on the table the key issues.

the parties at the table about how to proceed but i do think the first step is to have that conversation. >> emanuel charpontier and jennifer doudna. >> reporter: the high hopes and high stakes associated with crispr have catapulted doudna into a rare stratum of scientific celebrities. last year she and her research partner received the$3 million breakthrough prize in life sciences, which seems to be only the beginning. >> your name has been floated repeatedly for the winner of the nobel prize in science. >> i'm just incredibly honored and shocked to see that. i don't honestly think much about it. >> why you surprise when'd "time" named you one of the 100 most influential people? >> i was completely surprised. that came at me out of the blue. yeah. >> that's a pretty heady group. you're in with charlie rose and pope francis. >> yeah, i know. pretty interesting.

say it ain't so. basketball legend kobe bryant says he'll be hanging up his sneakers this season, retiring after 20 years on the hardwood. bryant has won five nba championships. he's been an all-star 17 times and is the third leading scorer in nba history. jeff glor has a look back at his brilliant career. >> reporter: bryant posted a 52-line farewell online sunday. maybe not a huge surprise. this is the end. but still a stunning career to see in full. >> kobe bryant. >> kobe. >> reporter: for the first time last night fans watched kobe bryant take the court knowing it would be his last season. >> a huge three. >> did you see that shot? >> i don't want to do this anymore. you know, and i'm okay with that. >> reporter: bryant posted a note online sunday called "dear basketball." in part saying "my heart can

my mind can handle the grind. but my body knows it's time to say good-bye." bryant's 37-year-old legs have betrayed him in recent seasons and he's missed major stretches. the generation behind him is half his age. >> mike, you've got to shoot it quick. >> i had you already. >> reporter: bryant himself had sprung from the era before that, when jordan dominated. both players stood out for their scarily intense desire to win. in 2001 bryant talked to charlie rose about his confidence on "60 minutes." >> i take you to this scene. 20 seconds left to go. you're down by one. you want the ball. you want to take the last shot. >> absolutely. i'm not afraid to fail, and i just love it. >> reporter: bryant's life and career were both thrown into question in 2003, when he was accused of rape. he was charged with sexual assault, but the case was dismissed and he settled a civil suit with the accuser.

>> come on. >> reporter: today he's about to end a 20-year nba career. he's not the same guy who once scored 81 points in a game. but he says he accepts that. >> it's the natural progression of growth and maturation. there's no sadness in that. i mean, i've had so many great times, right? i think i'm very appreciative of what i've had. >> bryant has struggled big-time this year, but the lakers are in rebuild mode. so his most important job may be that of mentor. at the end of his career making sure other players get the right start to theirs. that's the overnight news for this tuesday. for some of you the news continues. for others check back with us a little later for the morning news and "cbs this morning."
