0 more dollars than me. >> i wouldn't be as nervous in your chair as i am making a three-put putt. >> best of luck in the masters. great that you just popped in. >> thank you for having me. >> bubba watson, great to have him. that's all for us tonight. anderson cooper starts right now. good evening. get ready, breaking news tonight. millions of americans facing what could be the worst winter storm in a decade and a half. we'll show you who is in harm's way tonight. also, why did this man pump shot after shot into an suv full of teenagers? hear from the defendant himself in the loud music murder trial and decide whether to believe his story of self-defense. later, some kids covered their eyes because they could not bear to see a giraffe killed, cut up and fed to the lions? why did this zoo in denmark do this? we begin with breaking news. a winter storm that some fear will make atlanta's recent nightmare look like nothing. this is what two inches of snow and ice did to the city a couple weeks ago. the storm that's getting ready to pummel the southeast tonight could be the worst in 14 years. take a look at it from space, stretching from texas through virginia, and farther north along the eastern seaboard. it's in georgia, though, and the carolinas that will be the first to get the worst of it. not just out on the roads. even if you stay at home, you could end up in darkness for days when inches of ice meet miles of power lines. snow is falling north of atlanta. not wants to get caught off guard, the georgia governor declared a state of emergency, telling georgians, we are not kidding and we are not crying wolf. president obama has freed up federal resources in case things get bad. more than 2,000 flights have been canceled. delta employee also be sleeping in planes because there aren't enough hotel rooms. let's check in with chad myers. they're calling this storm potentially crippling. what should the southeast ex-snekt >> ice. and the ice is going to be rain on the way down and freeze when it gets down here. that's the issue. it's the ice that will collect on the trees and grow and grow and grow and then that tree will fall down. it has no choice because it's just simply too heavy. here is the storm right now. coming out of texas, into louisiana, but it's on its way to mississippi, alabama and georgia tonight. the issue is that aloft. anderson, i'm talking about 3,000 feet, up in the sky, it's going to be 36 degrees. that's because the warm air from the gulf of mexico is going to ride on top of the cold air. then that 36-degree rain is going to rain down into our atmosphere where it's going to be 29 and freeze. when it gets further to the north, lit be thick enough that it will be all snow in d.c., philadelphia, new york, probably 10 inches in new york city, 8 to 12 in washington, d.c. all the way up the east coast, boston, hartford, everywhere along i-95 gets the same storm. it's the ice storm down here that will bring down a million trees, a million power lines and leave some people without power for weeks. >> i was in texas this morning. i flew out of dallas. american airlines canceled flights, delta finally flew out this morning. but the storm is causing thousands of cancellations over the next couple of days at major airports. that's only going to get worse, right? >> here's what atlanta looks like. 36 degrees and nothing is going on. the problem is that there should be 100 or so planes in the sky to atlanta. there are 30. 30 planes in atl right now. all of the west coast planes have been canceled. all the planes that would be on the ground all night will not be on the ground all night. all those planes are leaving. they'll all get out of atlanta because they don't want to get buried in the ice except for the planes that the delta people will be sleeping in on the tarmac, because some of those seats do recline. it's going to be a rough night for all the people in the airports because this is going to be a devastating effect for wednesday, thursday, even into friday. >> i've not heard of crews sleeping on planes for a long time. by this time tomorrow morning, a florida jury could be deciding the kate on michael dunn, a man who opened fire on a car full of teaches. dunn took the stand, something that surprised a lot of people who followed the trial. dunn told jurors why he pumped shot after shot into the suv killing 17-year-old jordan davis. and then recounting what happened next. we have more from martin savidge. >> reporter: from the witness stand, 47-year-old michael dunn gave a simple reason for firing nine shots into an suv. >> i thought i was going to be killed>> reporter: he said he pulled into a gas station, parking next to a red dodge dur rango playing music so loud his vehicle was rattling. >> my eardrums were vibrating. >> reporter: while his fiance was in the store, he said he spoke to the teens. >> i said can you turn that down, please? they turned it off. >> at that point, what did you then say? >> i said thank you. >> reporter: moments later, he said the volume was back up and jordan davis in the back seat was using racially infused profanity that grew increasingly theory. >> i hear, i should kill that mother [ bleep ]. and i'm flabbergasted. i must not be hearing this right. >> reporter: dunn says he tried to deescalate the situation, asking are you talking to me? that's when he says davis reached for something. >> he reached forward and slammed it against the door. i saw sticking above like the window sil about four inches of a barrel. >> reporter: from then on he described an escalating series of threats and actions by the 17-year-old. >> now the door opens and this young man gets out and as his head clears the window frame, he says this [ bleep ] is going down now. this is the point where my death is imminent. >> reporter: dunn says he retrieved his gun from the glove box and fired nine shots into the suv, even stepping out of his own car to continue shooting as the suv drove off. >> i didn't aim, i pointed. >> reporter: he said he was afraid the suv would return. he then drove to the hotel never calling police. police say no one was found. on cross-examination, he never told his fiance the teens had a gun. dunn maintains he did. >> you never told the love of your life that those boys had a gun. >> you weren't there. >> reporter: it was the start of a contentious back and forth. guy said the two weeks very parked so close it would have been impossible for a raging jordan to get out as dunn said he did. he then said self-defense was not the real motive. >> jordan davis was never a threat to you, was he, mr. zmun >> absolutely he was. >> reporter: he said the following day he did report the incident, but the prosecution recalled dunn's fiance who confirmed dunn made no call. then she damaged his testimony even more when asked if dunn ever told her the teens were armed, something dunn swore he did -- >> did the defendant ever tell you he saw a gun in that red suv? >> no. >> did the defendant ever tell you he saw a weapon of any kind in that suv? >> no. >> there was no mention of a shotgun? >> no. >> there was no mention of a barrel? >> no. >> there was no mention of a led pipe? >> no. >> reporter: martin savidge, cnn, jacksonville, florida. >> let's bring in our legal analyst, sunny hosten, who was inside the courtroom today and mark geragos. it's interesting, he seemed very confident on the stand, and it's not often you see a defendant like that take the stand and then his fiance basically undercut a lot of the stuff that he so confidently said he told her. you were there for the testimony. what was it like in the courtroom? you think it was a good day for the government? >> yeah, i do think it was a good day for the government. i will tell you, anderson, that the courtroom was absolutely packed. people were shoulder to shoulder, and the jury was riveted when michael dunn was on the witness stand. so he probably did okay. but on cross-examination, i think that john guy played it just right. it was very well played. it was effective. it wasn't over the top. many people are saying he didn't do enough. well, that is what makes a good prosecutor. you don't want to go too far. you're never going to get the moment that jack nicholson and tom cruise got in "a few good men," where jack nicholson said, you're damn right i ordered the code red. what happened this time is john guy makes sure all the inconsistencies that michael dunn had came out in the rebuttal case. i thought that was so very effective. >> mark, what did you make of dunn's time on the stand? >> look, dunn had to take the stand. anybody that knows anything about self-defense knows they did not have in this case any other way to get a self-defense instruction. the problem is, with a fiance like that, who needs a wife? because she basically cut his legs off. as good as i think he did, she was devastating to him. >> so whatever in roads he made on the stand in convincing people, you think she just completely undercut him? >> look, right, because his testimony just taking it in a vacuum sounds convincing until you ask why didn't you call anybody and he said i can understand if he's shell shocked or something and called somebody the next day. then his fiance gets up there and pretty much undercuts that, undercuts him on the idea that he saw a gun. and that's pretty devastating stuff. a jury is going to say, wait a second, if his fiance is not going to lie for them and she's telling the truth, why would we believe anything he said? remember, one of the reasons defendants rarely take the stand is you don't talk about -- jurors don't talk about the prosecution case anymore, they talk about what did the defendant say? at this point, what the defendant said is very tough for him. >> sunny, i want to play more of what she said. dunn said there were a lot of inconsistencies about what he said he told his fiance. she then said that he never said anything about a gun. here's what he said during cross-examination. let's listen. >> how would you describe the weapon, did you say it was a sword, a machete? >> gun. >> you used the word gun? >> yes. >> when? >> multiple times. >> so that's pretty crucial, sunny. he says multiple times he said gun to his fiance and she says he never said it. >> that's right. it goes to the heart of this case. for the jury to find that he acted in self-defense with this justifiable use of force, they have to believe that he saw a gun. now, if he really saw a gun and fired in self-defense, the minute he got into that car, wouldn't he have said to his fiance, someone just tried to kill me, they had the girl of a shotgun pointed at me. she said he never said it on the way to the hotel room or on the way back home. he just never said it. i have to agree with mark, which i never do. i really think that she was the pivotal witness, the star witness really for the prosecution in this case. >> if you're concerned -- >> go ahead, mark. >> what's so perplexing is they know, the defense knows what she's going to say. it's not like it's a surprise. all of this stuff is predigested. so if that's going to happen, why are you putting this guy on to set himself up to get his legs cut off? >> if you're a concerned citizen, you just shot into a vehicle and you claim that there's a bunch of teenagers riding around with a we pop in your car, you would think he would call the police and say, there's some teens with guns in their car. let us know what you think at home on twitter. coming up next, this is outrageous. they say they're sending out tens of millions worth of medical supplies to one of the neediest countries on earth. the question is, why can't anyone find a trace of all those things they're supposedly sending? drew griffin has been looking and we're keeping them honest. you're going to want to see what he found. also, the man that did so much to honor the greatest generation, fighting perhaps his biggest battle. tom brokaw revealing his battle with cancer. dr. sanjay gupta joins us tonight. around here you don't make excuses. you make commitments. and when you can't live up to them, you own up, and make it right. some people think the kind of accountability that thrives on so many streets in this country has gone missing in the places where it's needed most. but i know you'll still find it when you know where to look.
