public on play may 1. >> i'm looking forward to visiting that library. thank you very much for watching. i'm w blitzer in "the situation room." erin burnett's "outfront" starts right now. "outfront" next. i'm erin burnett live in times square where the mayor of new york said today the suspected marathon bombers were headed to stage yet another attack. plus, we have the latest on the investigation. friends of dzhokhar tsarnaev are now being held in federal custody tonight. and the mother of the two alleged bombers, she says the whole thing was staged, there was no attack. the bizarre conspiracy in her own words. let's go "outfront." ♪ >> "outfront" tonight. this was the next target on the boston bomber's hit list.

the surviving suspect has told investigators that he and his brother were headed right here to times square in new york city to detonate more explosives before they were stopped. i'll have a lot more on this story from right here in times square. and we have all the other angles of the investigation covered tonight. in boston, drew griffin, david mattingly and brian todd. in rhode island, erin pike. nick robertson with new in fact on the suspect's parents. here's what we know. obviously you get a sense of how loud and busy it is here in times square. sit an incredibly busy place. hundreds of thousands come here today. here's what we know about the alleged plot to bomb times square. the younger son, dzhokhar, told investigators he and his brother tamerlan were driving to new york the night they ended up in

a gun fight with police after they killed a police officer and carjacked an suv. at first, he told investigators this trip was just to celebrate. but in later interrogations, when he was more lucid, he said they made a quote unquote spontaneous decision that night to use the bombs they had right here in times square. but even if it was a last-minute decision, new york city mayor michael bloomberg and police commissioner ray kelly said the attack could have been horrific. >> the two brothers had at their disposal six improvised explosive devices. one was a pressure cooker bomb similar to the two that exploded at the marathon. the other two were pipe bombs. >> mary snow is here with me tonight. when you see all the people here, you realize this is the center of this city, if not beyond. what do you know about the details of the plan? >> there aren't many details,

and the way the police commissioner and mayor described this, they were briefed by the fbi wednesday night. they said this was talk of targetingimesre. and the police commissioner said that the way he described this plan was that it was spontaneous. but he was told that the brothers had talked about this after they had, you know, carjacked a car that mercedes suv, and that is when this discussion came up. let's take a listen to what he had to say. >> that plan, however, fell apart when they realized that the vehicle that they hijacked was low on gas and ordered the driver to stop at a nearby gas station. the driver used the opportunity to escape and call the police. that eventually led to the shootout in watertown, where the older brother was killed in an exchange of gunfire with the police.

>> and, you know, the police commissioner and mayor say there are no specific threats to the city and knew of no specific targets, only that it was times square. >> again, you see all these people here. did the police say there's a lot of police presence here and those cameras helped to get the details from someone who tried to bomb times square a few years ago. how safe is this place, really? >> you know, you look around and in the heart of times square where we are, it's estimated close to 400,000 people pass through here every day, and there is an increased police presence and after the boston bombings, new york city stepped up the police presence. if you have people acting on their own, how safe can you be? as you mentioned, in 2010, a person was caught in that thwarted attempt to bomb times square just a few blocks from

here and it was a street vendor that stopped police. >> all right. mary snow, thank you very much reporting from times square. i want to go to boston and drew griffin. drew, i know you learned today that two strenfriends of the yo brother, dzhokhar tsarnaev, have been detained. do you know why they're being held? >> reporter: we do now, erin. there's been a lot of speculation about these two russian speaking students from kazakhstan at the university of massachusetts at dartmouth. last friday whine dzhokhar tsarnaev was still on the loose, agents staged a raid near that college. they put two russian students in handcuffs. those two students are still being held. they believe at the time that dzhokhar tsarnaev may have been in that apartment. that is why this raid was so

quote unquote heavy handed. and we know why they thought he was there, because tsarnaev was sharing a cell phone with one of these two russian speaking students. the fbi able to trace the cell phone records and work with social media to find out the location apparently of that cell phone. and they thought they were about to capture him. those two students now are being held on immigration visa issues with immigration enforcement control. as far as we can tell, there is no evidence they have anything to do with this plot. but they are being held and continue to be held on those immigration violations in the abundance of caution. basically, they're asking them questions. they're tracing all their electronic trails to make sure they know everything that dzhokhar and his brother tamerlan were doing before and after that bombing at the boston marathon. erin? >> drew, thank you very much. an interesting part of this

investigation, as you heard drew, as of now they are not saying they were involved. but still in custody many days later. i want to go to the russian republic where the suspect's parents live. huge developments there today. nick robertson is there. i know today the suspect's mother said she called an ambulance and the father or husband needed to go to the hospital. what's going on? >> reporter: yeah, the husband has health issues. he was at the press conference today or yesterday, thursday as it was. and he said no, i'm going to go to the united states today. i talked to him as he left that press conference, he said he was going to go and try to talk to his son in the hospital. but later on in the evening, we found out from his wife he had become too ill to travel. there was a thought he might travel on friday. that now seems unlikely.

so it's all up in the air. but that's kind of the narrative we've had from these parents in the situation so far, erin. >> i know the suspect's father said he's going to cooperate with investigators, but at the least i think i'm underselling this. the parents seem to be shooting down negative comments about their sons, the mother saying their sons were framed. are other parents really cooperating? >> it's hard to tell. they wouldn't answer specific questions about that and certainly the mother was saying some of those images you've seen with the backpack, you know, one of the sons leaving the backpack, she said that could have been changed by computers. so in denial, in confusion about the situation. they can't accept it. but we've heard about this character that so influenced tamerlan. when she described meeting him,

she said, i was ashamed. he came in, washed his hands, he prayed twice. she said after he left, not only was tamerlan influenced, but the mother also. she said she, after that meeting, that first meeting, was so impressed by this man, that she began regular and routine prayers as she said as a devout muslim. >> all right. thank you very much. and nick referencing the mother. we have late breaking news on the fact that the russians may have thought she was also a problem. we have that, and her denial of what happened last week in boston in her own words. because nothing can really capture it. i want to play it for you. that's coming up. and the distrust between the u.s. and russians, did it prevent americans from following up on tips from russia? and the mosque where some say tamerlan tsarnaev prayed. they say they don't add him up.

and why his wife has gone silent. what's your preferred search engine? search engine, uhh, probably google. if we do a side by side blind test comparison, and you end up choosing google, you get an xbox. i'll bet you the xbox, you bet me your son. well let's look up what you need. okay, i would do the left. yeah? what?! i am a daddy! bing wins it! bing won. bing did win. people prefer bing over google for the web's top searches. don't believe it? go to bingiton.com and see what you're missing. i've always had to keep my eye on her... but, i didn't always watch out for myself. with so much noise about health care... i tuned it all out. with unitedhealthcare, i get information that matters... my individual health profile. not random statistics. they even reward me for addressing my health risks. so i'm doing fine... but she's still going to give me a heart attack. we're more than 78,000 people looking out for more than 70 million americans. that's health in numbers. unitedhealthcare.

we are live tonight in times square. this is where authorities say that the suspected boston marathon bombers wanted to attack next. a place where you can see those behind me, up to 400,000 people a day come through this square. tonight, the justice department is under fire for how it handled its interrogation of the younger brother, dzhokhar tsarnaev. this would be crucial. mike rogers told cnn that tsarnaev was read his miranda rights too soon. >> once they walked into the hospital room and offered if

lawyer and mirandized, the subject has not continued to cooperate with authorities. that's a huge problem. >> that's a huge problem. deb, i know there are so many questions about this. what do you know about the reading of dzhokhar tsarnaev's miranda rights? >> i think what we know is that it's required by law to tell a suspect what his rights are, and what the justice department and the u.s. attorney's office here in boston saying this is just exactly according to protocol. any suggestion that the judge stepped in and interrupted any questioning of the defendant, dzhokhar tsarnaev, that's simply incorrect. fbi and prosecutors both were told that there was going to be a hearing set once they filed

the criminal complaint, then there is a certain amount of time in which the person has to come before a judge for initial appearance. even though it is rare that a judge will come to a bedside, it's not uncommon. it does happen. so the judge scheduled a hearing and the people who were there, it included the prosecutors, the federal defenders, the court reporter, the u.s. marshal service, and people from the hospital. so this was done the way it was supposed to be done. the suspect is entitled to know that he can remain silent and that he's entitled to an attorney. and any good lawyer would argue if that wasn't done, the case should have been thrown out because he wasn't read his rights. so we're getting strong pushback from the justice department and the u.s. attorney saying there's a system. you may not agree with it, but it works. clearly there's an issue of public safety. that's why even though this man was under a doctor's care, they allowed investigators from the

fbi to go in and to question him and the state he was in, he was heavy sedated, his hands were restrained, and they were able to go in every couple of hours to ask him a question or two for public safety, to make sure there weren't any other bombs, that there wasn't anybody else who was involved in this. so the politicians are basically saying this was done too soon, but this wasn't done in a vacuum. there are lots of very seriously smart people making the call how this case is going to be handled. >> deb, thank you very much. with all the key issues there, some real criticism happening tonight. major questions also remain about what our intelligence and law enforcement agencies knew about the tsarnaev brothers before the bombings last week. i spoke to congressman today and

started asking him about the brothers plans in times square, new york of a the boston bombings. >> they made a comment that they were going to go to new york. one comment i heard in the beginning might have been they were going to celebrate. the next thing you heard, they might go to attack. i think the police commissioner in new york was right, they had the capacity to drive 3 1/2 hours to do some kind of attack. >> people have also asked about this is a family that had been granted citizenship to this country because they were fleeing persecution. then the mother and father went back. people have asked if you were fleeing persecution, why would you go back? russia had asked the united states to check up on tamerlan tsarnaev and also on his mother. this is a woman who told cnn last night, the blood was paint, that this entire thing was a hoax and her son was framed.

so very deranged things. >> when russia contacted the fbi we investigated them for four months. we didn't find any information or any type of evidence that would show he was radicalized. after four months, we stopped the investigation. there was no more evidence there. during that period of time, we asked russia three times to give us more information and they never got back. as far as the mother is concerned, she's relevant. again, what happened when she went -- when tamerlan went back to russia? things changed when he came back. it seemed he was different. his personality was different. he had became a lot more orthodox in his religion. so this is another avenue hopefully russia will work with us. >> you're talking about the fbi and the cia and the question whether the ball was dropped anywhere. we do know now for a fact that tsarnaev was on three counterterrorism databases. senator lindsey graham said it

was a failure. i want to play for you what the senator said. >> boston is becoming to me a case study in system failure. between benghazi and boston, our systems are failing and we're going backwards. >> it's amazing, he was on all these lists and yet the fbi and the cia didn't know he spent six months in russia. he was on all these lists and when they had video of him, they didn't seem to notice this matched the guy in boston that was on the list and they had to go to the public. something seems to not add up. >> as far as lists are concerned, once the fbi stopped their investigate shun, they got no more information in four months. he was put on a list. that worked. why it worked is when he bought a plane ticket to go to russia, that kicked out and right away kicked out to the fbi and the fbi gave it to border patrol. so we knew as soon as he --

because he was just investigated, that when he bought a plane ticket, his name came up. >> he was there for six months in an area known for radicalism. wouldn't they at least check in to what he did? >> you raise a good question. the fbi is trained to follow the law. the justice department works with the fbi. the fbi is part of the justice department. so we need to relook at our standards. but we also want to protect our constitutional rights for americans, too. >> "outfront" next, we're staying with this story and more details about this mysterious misha that we keep hearing about. what the man some say that converted tamerlan tsarnaev to a radical form of islam. but first, did syria cross president obama's red line and

is syria crossing president obama's red line? defense secretary chuck hagel says there is evidence they used chemical weapons. is the administration now backing off big-time? jim acosta is in washington with

the latest. >> reporter: setting the stage for what could be a military showdown, defense secretary chuck hagel said u.s. intelligence officialed decided in the last 24 hours to warn the world that they suspect syria may have used chemical weapons in that country's civil war. potentially crossing a red line set by the white house. >> the u.s. intelligence community assesses with some degree of varying confidence that is syrian regime has used chemical weapons on a small scale in syria. >> reporter: adding that the we pops very likely have originated with the regime of syria's leader assad. it's a message president obama delivered during his visit to israel just last month. >> once we establish the facts, i have made clear that the use

of chemical weapons is a game changer. >> reporter: earlier this week, israeli intelligence officials found evidence that sarin gas has been used in two attacks in aleppo and near damascus. >> victims suffered from foaming from the mouth and other symptoms which indicate the use of chemical weapons. >> reporter: an account backed by syria's rebel leader. >> it was very clear that the regime used the chemical weapons. >> reporter: still, the obama administration is called on the united nations to investigate, saying there's a need for clear and credible evidence. white house officials are warning what happened the last time the u.s. rushed to war over weapons of mass destruction. a note of caution on the same day president obama attended the opening of president george bush's presidential library. >> i think it's pretty obvious

that red line has been crossed. >> reporter: john mccain saying it's time to consider military intervention. >> to provide a safe area for the opposition to operate. to establish a no-fly zone and provide weapons to the people in the resistance who we trust. >> reporter: white house officials aren't saying what evidence they're looking for. one thing that is clear here at the white house and on capitol hill, the calls are for an international effort to rid syria of chemical weapons. no one is saying the u.s. should go it alone. erin? >> thanks to you, jim. "outfront" next, brian todd has new details about the mystery man who may have convinced tamerlan tsarnaev to embrace a radical form of islam. plus, the mother of the two bombing suspects. she says the attacks were staged with red paint. this is too bizarre to be

i'm erin burnett live in times square tonight. we have new details about the mysterious man who may have convinced tamerlan tsarnaev who embrace a radical form of islam. his parents spoke to cnn openly about the man identified at this

point only as misha. and the influence that this man may have had on both their family and in particular, their oldest son. brian todd is "outfront" tonight in cambridge. >> reporter: the parents of bombing suspects tamerlan and dzhokhar tsarnaev give new details about a man named misha, who the mother says brought more religion into their home. >> when misha visited us, he just opened our eyes, you know, really wide about islam. he was really -- he is devoted and is very good, very nice man. >> reporter: but a man whose full name they say they don't know. the mother believes the first name might be mikhail. other relatives say they don't know the full name either. they describe misha as armenian, a convert to islam.

they say he has a brother who is a history professor and a father who is an athletic instructor. cnn cannot verify that information. there's no evidence that misha steered either of the brothers towards terrorism, but two other relatives say it was misha who made tamerlan tsarnaev turn toward a more radical form of islam. the mother describes the moment she and tamerlan became truly inspired by misha. >> i was ashamed when the one who converted was praying in our house, you know. we who the ones were born weren't praying. so after he left, we decided it was embarrassing for us to not be praying at least, you know?

so that's what happened. that's the moment. >> reporter: but there were reportedly other moments involving misha that created tension in the family. relatives say misha lived near the tsarnaev family apartment here in cambridge and came to visit at least twice. an uncle and former brother-in-law of the suspects have said that on one occasion, the father came home late at night and saw misha preaching to tamerlan tsarnaev. the father became angry and tried to get him to leave. that led to tension with the mother. one law enforcement official says he doesn't think misha has been located yet. >> a guy that's been identified by family members as the one who turned him radical would be a key figure, because how far did that radicalization go, and how much involved was this misha?

did he do more than just get tamerlan to change his philosophy about his religion? >> misha was crucial and when you hear about the family and the relationship, the family dynamic, who was more into islam with the parents and the son, who really called the shots here? >> reporter: erin, by every account that we're getting, including interviews that family members have done with cnn and other news organizations, every indication says that the mother, zubeidat, was the one more into islam and that the mother was the dominant figure in the family, that she called the shots, that people deferred to. also accounts that tamerlan carried a certain swagger in the family. but you're getting this picture that it was the mother and tamerlan who really were the ones that were bemt toward a

more pure and devout norm of islam than anybody else in the family. >> brian todd, thank you very much. the mother and tamerlan, we have breaking news right now. we are just learning that the russians also asked the united states to check up on the brother's mother. a crucial new development tonight. her name was actually added to a database called t.i.d.e., the terrorist identities data mart environment. her name was added at the same time her son tamerlan's name was also added to that database. obviously, this opens up the investigation even further. i want to go back to nick payson walsh is standing by. you had a chance to speak with the mother. any idea why she made authorities suspicious? >> reporter: there was, of course, the outstanding arrest

warms due to a shoplifting charge. that's obviously not it. if you listen to her describe how the whole family was converting towards a more devout form of islam, she makes out tamerlan was to inspire misha and asked her to cover up her hair and the son influenced even the mother. so you heard just a moment ago she talked about they had a sense of shame when they were confronted with how devout his faith was. so i'm sure if russian authorities were surveilling him, and she said -- the mother said he did attend the mosque here in his visit, they may have extended their investigation towards her. of course, we don't know precisely if the russians had any other information which may have caused these suspicions.

erin? >> and nick, we've also heard the mother deny that her sons could have been part of this. i was speechless, saying it was paint, it was a hoax. is there any chance she knew it was going on? >> reporter: it's difficult to say really. i'm meeting a woman who doesn't believe what she's seeing and will go to almost any possible length in her mind to avoid facing up to what u.s. authorities say her sons did. she didn't even talk about the fact that the fbi came to talk to her directly about the radicalization. >> they said that they just think tamerlan is kind of -- a little in the radical side of islam, and that they just don't want like -- they are keeping

their eye on, you know, the boys, like tamerlan, in the bombing. on the streets, like on the streets. >> they said we're going to be watching you? >> they said that we watch boys like tamerlan. >> reporter: now, there you had a strange picture of the fbi marking her son, admitting he went to an islamist mosque here. and insisting absolutely nothing was wrong. erin? >> nick, thank you very much. just a truly bizarre and seemingly deranged thing to say as she denies what happened. the other woman close to tamerlan tsarnaev was his wife, and she could be investigator's best source for piecing together his activity in the months

leading up to the attack. even in the days after, because she was with him all of that time. catherine russell has been in seclusion since her husband was killed, but there was some activity today outside of her home. erin, what's going on there? rhode island? >> reporter: i can tell you that there is a stepped up security presence here today. there are about half a dozen security vehicles stationed outside the russell house hold and every time one of her family members were leaving, there was a vehicle trailing them. she hasn't left the household in at least three days, erin. >> wow. so i know the best you understand now is katie russ emhas only been communicated through her attorneys. we don't know if she's spoken to fbi officials.

have they been at any point speaking to her, do you know? >> reporter: we still don't know the answer to that. what i can tell you is that as questions have begun to mount about katie russell and what she might ha might have known about tamerlan's activities, she would not talk to us. she simply said she was busy and couldn't answer any questions and she's been a little more helpful and told us that she's at least uncooperative with the fbi up to this point. right now they're really not talking. erin? >> erin, thank you very much. obviously, a lot of answers they want from her as she was living in the very small apartment with tamerlan and his brother, dzhokhar, as they were building pipe bombs and other bombs in that apartment. if tamerlan tsarnaev was practicing a radical form of islam, the big question is, why didn't anyone recognize that he was going in the wrong direction

and planning deadly violence? his family says they began to notice a change in his behavior in 2009. but what about the people he prayed with? because he went regularly to mosque in cambridge, massachusetts. >> reporter: worshipping under the roof of this mosque, the tsarnaev brothers aroused no suspicions they were planning deadly violence. now the mosque leadership has to defend itself against claims it is a haven for radicals. >> a lot of the claims made are simply false. there have been people coming in and out from this place. we have a congregation of 1300 people. >> charles jacobs is a critic of the islamic society of boston. >> they're aiming to transform the youth, particularly the youth, into more and more radical islamist beliefs.

>> reporter: he claims the group has had numerous affiliations with extremists. >> there have been several instances of people connected with terror and hate speech at that mosque. >> reporter: one figure is abdul a ham al-amudy. once consultded by presidents clinton and george w. bush, he was sentenced in 2004 to 23 years in prison for terrorist fund-raising and conspiring to murder the saudi prince. the isb says during his time there, he followed all rules and regulations. a defense similar when it comes to the tsarnaev brothers. they never expressed any sentiments of violent behavior. >> if we could have done more, we would have. >> the people who knew the brothers were immediately instructed to call the fbi.

the younger brother rarely attended services here, and the older brother only occasionally. it was his own actions that seemed to dispute the idea of a radical mosque. three months ago, he shouted at a preacher. charles jacob stopped short of accusing the mosque of having a hand in radicalization. is there any evidence that any of these teachers were used in red callizing the bombers? >> we don't know that. >> i know that there are is many questions. what happens to the members of the mosque find they have a radical in their midst, what do

they do? >> reporter: the litmus test seems to be violence. when you have someone like tamerlan tsarnaev standing up in a sermon, interrupting the sermon and then getting mad and angry and calling the minister names because he objected to how he was portraying dr. mortartin luther king, that didn't raise enough red flags. he continued to come to the mosque to tray but didn't necessarily come back to listen. he wasn't seen very often after that at any other sermons. >> thank you very much, david, reporting for us from boston.

up in boston. hey, anderson. >> we have more late breaking details in the investigation of how and why those two brothers off those two bombs here in boston. tonight's big question, was new york actually next? new york officials said they believe it was. we'll find out the details on that. also tonight, i interview one of the heroes of the blast. remarkable guy, firefighter, matt patterson. he was off duty that day, having a drink with his girlfriend when the first blast went off. he did what a lot of first responders did who were on duty. he ran right toward the blast. i will talk with him about how he scooped up a little girl who lost her leg. the sister of martin richard, who lost his life, he helped save martin's sister's life by his quick thinking and his actions. we'll talk to him. really, the interview will inspire you. plus a new training technique that could potentially prevent other kind of bombings, another boston marathon bomb from happening. bomb-sniffing dogs that have the

ability to sniff bomb vapors from unbelievable distances. all that at the top of the hour, erin. >> amazing about those dogs. we'll look forward to seeing you in a few minutes. now, i want to go to tonight's outer circle briefly, where we reach out to our sources around the world. tonight, we go to bangladesh, where rescuers are searching for survivors of a building collapse. local reports say 254 people have died, others may be at risk. we have the latest on the investigation. >> bangladesh officials say the building which housed a mall, a bank and several factories was not in compliance with safety rules and regulations. the country's high court has ordered the building owners and the owners of the factories to appear in court. now, some of the workers who survived that building collapse tell cnn that they actually saw massive cracks on the seventh floor of the building on tuesday, and had expressed their concern, but the factory owners told them there was nothing to worry about, and ordered them to report to work. now more than 36 hours since

that building collapsed, scenes of complete desperation as rescue workers are still scrambling to pull out as many survivors as they can. eyewitnesss tell us they can still hear people yelling from underneath that rubble, asking, crying for help. so far, 2,000 people have been rescued, but many more are still trapped. erin? >> of course, people here in the u.s. need to pay close attention to that. that factory, people in there made a lot of clothes that we buy here in the united states. 14 boston bombing victims have had at least one limb amputated, completely and utterly changing their lives. that number may still rise. heather abbott was hit by the second blast, just outside the forum bar. incredibly quick and brave work by first responders and doctors initially saved her leg, but when surgeons went in for a follow-up look, they saw a lot of damage. they told her that amputation below the knee might be her best option.

today, heather talked about losing her lower leg. >> although it's something that certainly i wouldn't wish upon myself or anyone else, you know, it's really not as bad as i thought it could have been. i really think i'm going to be able to live my life in a normal way eventually when i get that permanent prosthesis. >> incredibly amazing thing to say. dr. sanjay gupta joins me now. sanjay, why did heather have to make this decision, and i know also that it was really her decision, right, not necessarily the doctor? >> that's right. typically, it is the patient's decision. i mean, look, there's going to be some situations where it's just a clear-cut decision, where it will be clear that the leg cannot be saved. on the other side of things, it's going to be very clear the operations are going to save the leg. what typically happens is you do all the things to restore the bone, stabilize the bone, repair the arteries and nerves, and then you sort of see how is the patient doing, and sometimes the leg just does not regain that

function. sometimes there's just -- it becomes such a source of pain that it sort of creates the decision again, but to your question, it is the patient's decision ultimately. erin, this is how her doctor put it. >> it's very, very rare that the doctor makes the decision. we do everything to let the patient come to their own decision on this, because values for every separate patient are different, and keeping a limb may be very important to one, while for someone else, i think like heather, function is paramount. >> it's a heartbreaking and tough decision, as you might imagine. but the patient usually makes that decision with a lot of guidance and input from the doctors, erin. >> sanjay, i know that heather was in the hospital for a week before she had to make this choice, this choice that would terrify anyone. are there other victims out there who thought they were all right, who think they will get through this, who may have to

make this decision down the line? >> that is quite possible. the scenario is typically this, that the leg was obviously badly injured, everything is being done in terms of preventing infections, stabilizing the bone, all of that again, and then it's a little bit of a wait and see, erin. there's no hard and fast rule in terms of how long you wait and see and as the doctor said, there are some patients who are going to just for all sorts of different reasons, are going to err much more on the side of trying to save the limb. but at some point, again, if the leg is just not regaining function, if it's just -- if it becomes such a source of pain that cannot be controlled, then at that point the patient may make a decision and that could be, you know, several days or weeks from now. >> all right, sanjay gupta, thank you very much. just incredible to watch heather abbott. inspiring. thank you. sweet caroline and an even sweeter gesture by the man who sings it is next. ♪
